IBM System x3850 M2 / x3950 M2

Outstanding performance, superior mainframe-like reliability, and fault-tolerant memory characteristics

IBM® has been designing and implementing chipsets under the X-ArchitectureTM name since 2001. eX4 technology represents the fourth generation of products based on the same design principle IBM began with in 1997: to offer systems that are expandable, offer “big iron” reliability, availability, and serviceability (RAS) features, with extremely competitive price/performance on an Intel® Xeon® MP processor-based system.

The eX4 technology is primarily designed around three major workloads. These workloads are database servers, server consolidation using virtualization services, and Enterprise Resource Planning (application and database) servers.

If you are adopting industry-standard Xeon EM64T servers for running business critical applications, the systems that run these applications need the type of technology designed into IBM’s eX4 technology systems. The eX4 chipset represents a $100M+ investment in designing a flagship offering that can harness the power of 4-socket-and-up 64-bit x86 (x64) Xeon MP processors. The eX4 design includes two 4U 4-socket rack-optimized chassis (x3850 M2 and x3950 M2) with the ability to scale up to 16 sockets and up to 64 cores. In fact, you can start with a single-node x3850 M2 chassis, and by adding a ScaleXpander Option Kit, you can turn it into an x3950 M2, ready to expand into a multi-node configuration providing more flexibility in deploying your scalable solution than ever before.

17 The x3850 M2 now offers selected models integrated with VMware ESXi 3.5 preloaded on an IBM 4GB USB 2.0 Flash Key. It operates in a diskless configuration, offers a smaller memory footprint, extremely high performance, and stronger security, making getting a system up and running in a virtualized environment faster and easier than ever before.

IBM X-Architecture pioneered XpandOnDemandTM (“pay as you grow”) scalability, which allows chassis to be simply cabled together to form larger scale-up systems. This unique capability allows IBM to sell a large SMP (symmetric multiprocessing) system at entry price points. Other Intel OEMs can’t match this capability. If they offer a 16-socket product at all, they require you to start out with a 16-socket chassis, whether you’ll ever grow into it or not. With XpandOnDemand, you can start small, with a 4- or 8-socket configuration, and later expand as your needs change, without requiring you to buy more than you need up-front or throw away parts later as you expand.

IBM’s eX4 technology-based systems are the ideal solution for scale-up database-serving applications on Microsoft® Windows® with Microsoft SQL Server® or IBM DB2®, as well as Linux® with Oracle 9i RAC and 10g, or IBM DB2. Database hosting demands ultimate server reliability features, and once installed, they grow and grow. The eX4 design offers two strong selling arguments against the competition: lower initial purchase price, and potentially much lower long- term TCO.

Another strong application area for the eX4-based systems is enterprise server consolidation activities. Larger servers have more processor, memory and I/O resources, which make maximum use of any applicable virtual machine software licensing fees and deliver superior system utilization levels. The name of the game in consolidation activities is to deploy the fewest new servers possible and help IT staff manage more images with the same or fewer overall people.

One of the fastest growing application areas for eX4-based systems is ERP workloads, including SAP and Oracle. eX4-based systems can offer considerable savings over UNIX deployments, using our certified solution stacks on either Windows or Linux.

The 4-socket eX4 servers are designed to protect your data with high performance, high reliability, and high availability. They support the latest quad- and dual-core Intel® XeonTM MP processors, designed with high-performance quad 1066MHz front-side buses (FSB), 64-bit extensions (EM64T), and either 8MB (dual-core) or 4MB, 6MB, or 8MB (quad-core) of L2 cache, to help provide you with the computing power you need to match your business needs and growth. In addition, the x3850 M2 and x3950 M2 use industry-standard DDR II memory

with ChipkillTM ECC (Error Checking and Correcting) protection—for high performance and reliability and lower energy consumption than fully buffered memory. For even higher levels of availability, the eX4 servers also offer Memory ProteXionTM, memory scrubbing, and optional memory mirroring. A dual-port integrated high-speed Gigabit Ethernet controller with TOE (TCP Offload Engine) is standard (support available in 1Q08), as are seven high-performance PCI-E x8 adapter slots.

The x3850 M2 and x3950 M2 offer industry-leading scalability, including quad-processor support (upgradeable to 16 processors/64 cores), up to 256GB of memory (upgradeable to 1TB) and high-performance up to four 2.5-inch internal Serial-Attach SCSI (SAS) hot-swap hard disk drives with an internal storage capacity of 587.2GB. Hardware-based RAID-0/1 support is standard. An optional IBM ServeRAID-MR10k SAS RAID controller adds 256MB of battery-backed cache to the onboard controller to provide five additional RAID levels, including RAID-10/5/50/6/60. The 4U size of the chassis helps you maximize your rack investments. Up to 10 of these servers can be installed in a single 42U rack, for a total of up to 40 processors, 70 PCI-E slots, and 40 HDDs, offering an ideal balance of performance, storage and I/O slots per rack. Optional Advanced Connectivity Technology (ACT) interconnect cabling helps reduce cable clutter and cost and minimizes installation time when interconnecting many rack-mounted servers.

Standard in both the x3850 M2 and the x3950 M2 is the Remote Supervisor Adapter II that communicates with the Baseboard Management Controller (BMC) to enable the user to manage and control the server easily—both locally and remotely. This high level of manageability is designed to help keep management costs down and the system up. The drop- down light path diagnostics panel enables quick servicing of the system if a problem develops. These advanced features help maximize network availability by increasing uptime, as do hot- swap/redundant HDDs, power and fans; Active MemoryTM; temperature-controlled fans with Calibrated Vectored CoolingTM; IPMI 2.0 support, including highly secure remote power control and Serial over LAN; as well as text- and graphics-console redirect over LAN.

With the inclusion of unique IBM service and support features such as IBM Director, IBM Systems Director Active Energy Manager for x86 (formerly known as PowerExecutive), and IBM ServerGuideTM, the x3650 is designed for maximum uptime.

If you need a balance of high-performance four-socket processing, scalability beyond eight sockets, and large I/O capacity in a rack-dense environment, these are the ideal systems.

Combining high-performance architecture with high-performance Xeon MP processors

Key Features

IBM System x3950 M2-specific

  • ScaleXpander Kit standard
  • Offers physical partitioning at a four-socket granularity allowing you to run multiple operating systems on the same integrated hardware
  • Support for up to two ServeRAID-MR10k options if multi-node High-Performance Xeon MP ProcessorsThe x3850 M2 and x3950 M2 ship with two high-performance Intel Xeon MP processors, and support up to four, allowing you to upgrade as business needs require. The eX4 servers also go a step further by allowing you to add additional nodes (chassis) to increase the number of sockets from 4 to as many as 16 (using four total chassis). With multiple chassis, you can use physical partitioning to segment the one physical server into multiple logical servers for virtualization.Processors can be added or replaced through the top cover of the system. The system offers a choice of processor clock rates, FSB speeds and power draw:
  • 130W quad-core Xeon processor model X7350 at 2.93GHz, with 64-bit extensions, 32.5W per core of power draw, a 1066MHz FSB, and 8MB of L2 processor cache (2 x 4MB)
  • 80W quad-core Xeon processor model or E7330 at 2.4GHz, with 64-bit extensions, low power draw (20W per core), a 1066MHz FSB, and 6MB of L2 processor cache (2 x 3MB)
  • 80W quad-core Xeon processor models E7320 at 2.13GHz, with 64-bit extensions, low power draw (20W per core), a 1066MHz FSB, and 4MB of L2 processor cache (2 x 2MB)
  • 80W dual-core Xeon processor model E7210 at 2.4GHz, with 64-bit extensions, 40W per core of power draw, a 1066MHz FSB, and 8MB of L2 processor cache (2 x 4MB)The dual-core Xeon MP processors contain two complete processor cores. Each processor contains two 4MB L2 caches, one per core (8MB total per processor). The two cores appear to software as separate physical processors. The dual-core processors can offer considerably higher performance than a same-speed single core Xeon processor (depending on workload). Similarly, quad-core Xeon MP processors contain four processor cores. The cores share dual 2MB, 3MB, or 4MB L2 caches (4MB-to-8MB total per processor). That is, two cores per L2 cache. They can offer much greater total performance than dual-core Xeon MP processors (again, depending on workload).The eX4 servers also include an industry-exclusive L4 cache called XceL4v Dynamic Server Cache.The servers provide four separate 1066MHz FSBs (front-side buses), one per processor. Each of the four FSBs (which connect memory to the processor) boasts a peak rate of 8.53GBps (34.1GBps aggregate).This contrasts to the two 667MHz FSBs (with two processors per FSB) provided in the original x3850 models. In other words, you now have twice as many FSBs as before and each is 60% faster than before.

    Intel Extended Memory 64 Technology (EM64T) 64-bit extensions allow the Xeon processor to use large memory addressing when running with a 64-bit operating system. This in turn lets individual software processes directly access more than 4GB of RAM, which was the limit of 32- bit addressing. This can result in much higher performance for certain kinds of programs, such as database management and CAD. Additional registers and instructions (SSE3) can further boost performance for applications written to use them. Customers should contact their software provider to determine their software support for EM64T.

    Intel’s Virtualization Technology (VT) integrates hardware-level virtualization hooks that allow operating system vendors to better utilize the hardware for virtualization workloads, a key workload for the eX4 platform.

    eX4 Chipset ‘Snoop’ Filtering

    One of the core features of the eX4 chipset that gives the platform its performance advantage is the ‘snoop’ filter. The Xeon Coherency Protocol or ‘snoop’ is an operation that happens every time a processor in an SMP system needs to update a memory address during normal operation. The ‘snoop’ is when the processor getting ready to operate on a piece of data asks the remaining processors in the SMP complex to verify they have not modified the same piece of data without writing back from their cache. This operation increases traffic on the front side bus.

    The eX4 chipset contains 324MB of EDRAM within the Northbridge chip. This copies all data as it is written to the processor cache, allowing the chipset to respond directly to the processor snoop requests. This reduces the overall traffic across the FSB and helps to improve system

performance over other architectures.
(Intel now offers a first-generation snoop filter in their 7300 chipset; however it contains only

64MB of RAM which is 80% smaller than the eX4 fourth-generation solution.) XceL4v Dynamic Server Cache

Another performance feature of the eX4 chipset is the XceL4v L4 cache. When using a single node (chassis), the cache works with the snoop filter to help reduce FSB traffic. When more than one node is used, 256MB of virtual cache per node (taken from main memory) is used for interprocessor communications between chassis, to keep data in synch. This not only compensates for any performance hit that might otherwise result from sending data across the relatively great distances between processors in multiple chassis, it actually results in a performance improvement versus a single chassis.

This feature is a unique IBM enhancement, not offered by other x86 server architectures (using either Intel or AMD processors).

DDR II ECC Memory with Active Memory Protection

The eX4 servers support up to 256GB of memory per node (chassis) in 32 DIMM sockets (up to 1TB for a 4-node/16-processor configuration). It uses PC5300 double data rate II (DDR II) memory (operating at 533MHz) for faster access, and provides IBM Active MemoryTM features, including advanced IBM Chipkill memory protection, for up to 16X better error correction than standard ECC memory, IBM Memory ProteXion, hot-add/hot-swap memory support, and optional memory mirroring. (Notes: Hot-add capability requires operating system support. Hot- add memory and mirroring are mutually exclusive. Conversely, hot-swap requires mirroring.)

The standard configuration includes two memory cards, which support up to eight DIMMs apiece. The system is upgradeable to four memory cards with eight DIMMs each. With configurations of 8-to-16 DIMMs, using two memory cards saves cost, but using four cards increases performance. (With more than 16 DIMMs, four memory cards are required.)

The memory architecture of the eX4 chipset provides up to 60% more aggregate memory bandwidth (up to 34.1GBps when using four memory cards) for exceptional memory performance vs. a maximum of 21.3GBps bandwidth in the previous generation) and up to quadruple the system memory capacity of the predecessor x3850 server (64GB). By performing reads and writes simultaneously, it eliminates the previous memory read-to-write blocking latency. In addition, it also offers innovative data reliability and security features to help improve data integrity, including enhanced CRC protection, data retry on error detect and buffer registers for improved fault isolation. Even running at 533Mhz, with twice the number of channels and twice the DIMM capacity supported, the x3850 M2 and x3950 M2 deliver a memory subsystem with greater throughput than the competition.

Memory ProteXion technology (also called redundant bit steering) provides multichip error protection, and works in conjunction with Chipkill technology—which provides multibit protection per chip—and standard ECC protection, to provide three-level memory correction. For increased availability, the eX4 design offers an additional level of Active Memory protection: online memory mirroring.

Memory mirroring works much like disk mirroring. The total memory is divided into two channels. Data is written concurrently to both channels. If a DIMM fails in one of the DIMMs in the primary channel, it is instantly disabled and the mirrored (backup) memory in the other channel becomes active (primary) until the failing DIMM is replaced. Note: Mirroring requires DIMMs to be installed in multiples of four (one pair per memory channel).

A secondary benefit of memory mirroring is that the failed memory DIMM and its card can be hot-swapped out to replace the failed DIMM. This feature requires no device driver for the operating system.

DIMMs must be installed in matching pairs. Memory is available in kits consisting of two 1GB, 2GB, 4GB or 8GB DIMMs.

Flexible Internal Storage Capacity

The eX4 servers offer a choice of internal storage, supporting up to four (2.5-inch) hot-swap high-performance Serial-Attach SCSI (SAS) drives, as well as an integrated 4GB USB 2.0 Flash Key with VMware ESXi preloaded (selected models) for the embedded virtualization hypervisor.

2.5-inch SAS
• 10,000 RPMs — 73.4 or 146.8GB (587.2GB maximum)

Please see the Legal Information section for important notices and information.

Combining high-performance architecture with high-performance Xeon MP processors

• 15,000 RPMs — 73.4GB (293.6GB)
2-5-inch drives not only require less space than 3.5-inch drives, they weigh less, consume half

the power, produce less noise, seek faster, and offer increased reliability.

The hot-swap SAS drives use the Converged Tray for interchangeability with other IBM System xTM systems. If you need more storage space, terabyte capacities are possible with external direct-attach NAS and SAN solutions.

Integrated Virtualization

Selected models of the x3850 M2 ship with an IBM 4GB USB 2.0 Flash Key installed preloaded with VMware ESXi 3.5. This is an embedded version of VMware ESX 3.5. It is fully contained on the flash drive, without requiring any disk space. Rather than management through a Service Console based on a Linux operating system, ESXi 3.5 relies on aggregate management tools, including VirtualCenter, the Remote Command Line interface and the introduction of CIM for standards-based and agentless hardware monitoring.

VMware ESXi 3.5 includes all the performance, scalability and compatibility features of ESX 3.5, including full VMFS support across FC SAN, iSCSI SAN, and NAS, and 4-way VSMP. Because it runs from flash memory, it’s extremely fast and ideal for diskless configurations. It also offers enhanced security, because it runs without an operating system-based console and is updated/patched mush like firmware. Licensing works the same as for “standard” ESX 3.5.

Disk/Tape Controllers
All models include an integrated eight-port LSI 1078 Serial-Attach SCSI (SAS) controller. This

controller supports up to four internal SAS LVD (low-voltage differential) drives.

The integrated SAS controller offers hardware RAID-0/1 support for those SAS drives. The ServeRAID-MR10k option adds additional RAID levels, including RAID-10, 5, 50, 6 and 60, along with 256MB of battery-backed cache memory for higher performance and data integrity, without consuming a valuable PCI-E adapter slot.

The SAS controller provides data transfer speeds of up to 300MB per second1 in each direction (full-duplex) across the SAS bus, for an aggregate speed of 600MBps, nearly double that of Ultra320 SCSI’s 320MBps (half-duplex) bandwidth. The serial design of the SAS bus allows maximum performance to be maintained as additional drives are added.

Additional external SAS/SATA disk storage, as well as tape backup, is available using the external SAS port on the system unit, or via one of several supported iSCSI or FC SAN controllers.

Drive Bays
The eX4 servers contain five drive bays (per chassis) in all—including four 2.5-inch HDD bays

that support hot-swap SAS drives totaling up to 587.6GB.

A 24X/10X/24X/8X2 speed (ultraslim, 0.5”) CD-RW/DVD-ROM combo drive with an IDE interface ships standard in all x3850 M2 and x3950 M2 servers. No floppy drive is supplied with any model; an external USB floppy drive may be used, if needed.

For still more storage, a direct-attach, iSCSI, or FC SAN external expansion option can be added, using an optional controller.

High-Performance Adapter Slots

There are seven physical x8 (“by 8”) PCI-E (PCI Express) adapter slots standard (per chassis). Each is capable of supporting x4 or x8 adapters. All slots are half-length/full-height. Electrically they are x8 slots as well (meaning that they operate at full x8 4GBps speeds). Slots 6 and 7 are ActiveTM PCI-E hot-add/hot-swap slots, offering the capability to add or replace adapters without having to shut down the system.

PCI-Express is a high-performance, low-latency, next-generation serial I/O bus that is rapidly replacing the older parallel PCI and PCI-X buses. A x8 PCI-E adapter offers approximately four times the maximum throughput of a 133MHz PCI-X adapter3. (A x1 adapter offers throughput similar to a 66MHz PCI-X slot.)

Because the SAS, ServeRAID-MR10k, dual Gigabit Ethernet, and systems management controllers are integrated onto the system board, the seven adapter slots are all available, which offers you a wide degree of latitude in expansion options.

(Even though the HP DL580G5 has eleven total slots, they offer lower throughput, providing no

more aggregate bandwidth than the seven slots of the eX4 servers.)

Dual Gigabit Ethernet Controller

The eX4 systems include one integrated dual-port Broadcom 5709C Gigabit Ethernet controller, with TOE (TCP Offload Engine) acceleration support (available 1Q/08), as well as load-balancing and failover capabilities between the two ports.

TOE support helps improve overall system performance by offloading TCP/IP protocol processing from the system microprocessor to the onboard Ethernet TOE processor. iSCSI support works similarly for iSCSI workloads.

The controller also supports highly secure remote power management using IPMI 2.0, plus Wake on LAN® and PXE (Preboot Execution Environment) flash interface. Optional PCI adapters offering failover and load balancing between adapters are available for added throughput and increased system availability.

Ultra-Efficient Cooling

Six strategically located hot-swap/redundant fans, combined with efficient airflow paths, provide highly effective system cooling for the eX4 systems, known as Calibrated Vectored Cooling. The fans are arranged to cool three separate zones, left, center, and right, with one pair of redundant fans per zone.

The fans automatically adjust speeds in response to changing thermal requirements, depending on the zone, redundancy, and internal temperatures. When the temperature inside the server increases, the fans speed up to maintain the proper ambient temperature. When the temperature returns to a normal operating level, the fans return to their default speed. Why not simply run the fans at 100% capacity all the time? For several good reasons: to reduce the ambient noise, reduce the wear-and-tear on the fans and reduce the server power draw. The reduction in ambient noise and power draw may be relatively minor for a single server, but if you have a larger number of systems the aggregate savings in power and noise pressure can be significant.

In addition, the server uses hexagonal ventilation holes in the chassis. Hexagonal holes can be grouped more densely than round holes, providing greater airflow through the system cover.

This cooling scheme is important because newer, more powerful processors generate a significant amount of heat, and heat must be controlled for the system to function properly.

Hot-Swap/Redundant Components

System availability is maximized through the extensive use of hot-swap and redundant components, including:

  • Hot-add/hot-swap redundant memory protection (with Chipkill, Memory ProteXion, and optional memory mirroring capabilities)
  • Hot-swap redundant hard disk drives (with standard LSI 1078 controller and optional ServeRAID-MR10k providing multiple levels of RAID)
  • Hot-swap redundant cooling fans (three redundant pairs)
  • Hot-swap redundant power supplies (at 220V both power supplies are redundant; at110V only the first power supply is redundant)Light Path DiagnosticsLight path diagnostics enables a technician to quickly identify and locate a failed or failing system component, such as a specific memory DIMM. (Monitored components include processors, memory, power supplies, fans, HDDs, adapters, and voltage regulator modules (VRMs), plus system temperature.) This enables quick replacement of the component, which helps increase server uptime and lower operating costs.

    The front of the server has an LED indicator light to show possible component failures. If the front LED indicates an error condition, by pressing a button on the front of the server an LED panel will pop out and drop down for easy viewing without the need to open the server cover or remove the server from the rack. The light path diagnostics panel tells the servicer which component requires attention. In addition, many components have their own identifying LEDs. For example, each of the memory modules has an LED next to the socket, as do all processors, all adapter slots, all fans, all power supplies, all voltage regulator modules and the service processor, allowing the servicer to easily identify exactly which component needs servicing. By following the “light path,” the component can be replaced quickly, and without guesswork. (Note:

    2 Variable read rate. Actual playback speed varies and is often less than the maximum possible. 3 Actual throughput will depend on the adapter vendor’s implementation.

Please see the Legal Information section for important notices and information.

Combining high-performance architecture with high-performance Xeon MP processors

In the event of a failed DIMM, the system will restart and mark the DIMM as bad while offline, thus allowing the system to continue running, with reduced memory capacity, until serviced.)

In addition to the outstanding diagnostic detection, there is a new feature with a digital readout that indicates at what stage of the boot process your system may have experienced trouble. This can reduce the troubleshooting time and help get your system up and running quickly and efficiently.

Other Features

  • Trusted Platform Module standard — This module provides a highly secure start-up process from power-on through hand-off to the operating system boot loader. ACPI support is provided to allow ACPI-enabled operating systems to access the security features of this module. (TCG V1.2-compliant.)
  • Six USB 2.0 ports — Provides flexibility to add high-speed external devices. The USB 2.0 specification supports up to 480Mbps transfer rates. (Note: Not all USB 2.0 devices are capable of achieving this rate.) Two ports are provided on the front of the server, three are on the back, and one is internal to support the embedded 4GB USB 2.0 Flash Memory Key in selected models.
  • Remote Supervisor Adapter II standard — This full-function systems management adapter provides local and remote management functions in a dedicated PCI-X slot, without consuming one of the seven PCI-E adapter slots.
  • Video — An ATI Radeon ES1000 SVGA video controller on the Remote Supervisor Adapter II provides up to 1024×768 resolution, with a color depth of 32 bits at 85Hz refresh rate, with 16MB of video memory.
  • Toolless slides — Allows quick rack installation and quicker upgrade and servicing of the server.
  • Toolless chassis — The cover can be opened without tools, and many components can be removed and replaced without tools, including the CD-RW/DVD combo drive, hot-add/hot- swap memory, hot-swap HDDs, adapters, and the integrated optional ServeRAID-MR10k and Remote Supervisor Adapter II. This can save a servicer significant time.Rack Cable Management and KVM Console SwitchingIBM Advanced Cabling Technology (ACT) is an optional feature that offers many advantages over standard KVM cabling across the entire System x and xSeries product line. So now you can interconnect all of your servers with one smart cabling architecture. ACT cabling eliminates the need for one-to-one direct connections between each server and a KVM switch by using a daisy-chain approach.The snarl of cabling behind most racks is at best inconvenient to work around and at worst an expensive logistical nightmare, requiring the rewiring of servers, PDUs, KVM switches, and other equipment whenever a rack server is added or removed. Even worse, the veil of cables blocks rack airflow and can actually contribute to equipment failure due to overheating. ACT cabling is the solution for reducing behind-the-rack cabling by as much as 87%.

The illustration below shows a sample ACT configuration:

Via Secondary Switch

Combining high-performance architecture with high-performance Xeon MP processors

Conventional cabling has bulky KVM cables exiting each server, which then connect to a KVM switch. The cables exiting a series of KVM switches must then be aggregated via additional KVM switches and PDUs, which only increases the number—and cost—of cables, KVM switches and PDUs. Instead, the daisy-chain approach of ACT cabling uses readily available, inexpensive CAT5 and 6 cabling to considerably reduce the number of cables, KVM switches, and PDUs needed, rather than increasing them. If a server is removed or added, no complicated rewiring is needed. One cable connects the first server in the rack to the next, and so on. Up to 16 servers form a chain; up to 8 chains can connect to one Local Console Manager (LCM); 16 LCMs can connect to one Global Console Manager (GCM). In this manner, up to 2,048 servers can be centrally managed. Equally importantly, with ACT—unlike some other offerings— everything is done externally via cabling; no special adapters are required.

Extensive System Support Features

The IBM services and technical support portfolio provides world-class, consistent, high-quality service and support. The eX4 servers offers a number of tools and services designed to make ownership a positive experience. From the start, IBM programs make it easier for you to plan for, configure and purchase System x or xSeries servers, get them running and keep them running long-term. These features include IBM Express Portfolio, IBM ServerProven®, the IBM Standalone Solutions Configuration Tool, IBM System x and BladeCenter Power Configurator, IBM ServerGuide, IBM Electronic Service AgentTM, Product Customization Services and extensive technical support offerings.

The IBM ServerProven program provides the confidence that specific options and operating systems have been tested on the server and are officially supported to work together. It is updated frequently to ensure that the latest compatibility information is always at your fingertips.

The IBM Standalone Solutions Configuration Tool (SSCT) is a downloadable tool that simplifies the often complex chore of configuring a full rack of servers (including blade servers) and confirming that you have all the cables, power distribution units, KVM (keyboard, video and mouse) switch boxes and other components you need, as well as the proper airflow clearances, electrical circuits and other environmental conditions.

IBM System x and BladeCenter Power Configurator helps IT managers plan for data center power needs, by providing the following information for specific configurations of System x and BladeCenter systems: power input (watts), PDU sizing (amps), heat output (BTUs), airflow requirements through chassis (CFM), VA rating, leakage current (mA), and peak inrush current (amps).

IBM ServerGuide (installed from CD) simplifies the process of installing and configuring System x and xSeries servers. ServerGuide goes beyond mere hardware configuration by assisting with the automated installation of the Microsoft® Windows® Server 2000 and 2003 operating systems, device drivers and other system components, with minimal user intervention. (Drivers are also included for support of Novell NetWare, Red Hat Linux and SUSE LINUX.) This focus on deployment helps you reduce both your total cost of ownership and the complexity that administrators and technical personnel face.

IBM Electronic Service AgentTM is an innovative “call home” feature that allows System x and BladeCenter servers to automatically report hardware problems to IBM support, which can even dispatch onsite service4 if necessary to those customers entitled to onsite support under the terms of their warranty or an IBM Maintenance Agreement. Electronic Service Agent resides on a server and provides electronic support and problem management capabilities through a highly secure electronic dialogue between your systems and IBM. It monitors networked servers for hardware errors and it can perform hardware and software inventories and report inventory changes to IBM. All information sent to IBM is stored in a highly secure database and used for improved problem determination.

Additional services include hardware warranty upgrades and factory-installed Product Customization Services (PCS), such as asset tagging, hardware integration, software imaging and operating systems personalization.

IBM offers extensive technical support by phone and via the Web. Support options include links to forums/newsgroups, problem submission, online shopping support, service offerings, device drivers for all IBM product lines, software downloads and even upcoming technical seminar worldwide schedules and registration. Also available are remote installation, configuration and usage support for System x and xSeries hardware and software, as well as onsite custom services to provide the level of expertise you require.

4 For onsite labor, IBM will attempt to diagnose and resolve the problem remotely before sending a technician.

Combining high-performance architecture with high-performance Xeon MP processors

Advanced Systems Management Capabilities

The x3850 M2 and x3950 M2 have a high level of systems management capabilities that are well-suited to remote locations as well as to stand-alone environments. Features include the Baseboard Management Controller (BMC), IBM Systems Director Active Energy Manager for x86 (formerly known as PowerExecutive), Automatic Server Restart, Wake on LAN® support, PXE support, text console redirect, Predictive Failure Analysis, IBM Director, IBM Systems Director Active Energy Manager for x86, and the Remote Supervisor Adapter II.

The BMC provides industry-standard Intelligent Platform Management Interface (IPMI) 2.0- compliant systems management. It provides a number of important system functions, including:

  • Monitoring of system and battery voltage, system temperature, fans, power supplies, processor and DIMM status
  • Fan speed control
  • Product ID and Family ID detection
  • Highly secure remote power on/off
  • System reset control
  • NMI/SMI detection and generation
  • System diagnostic LED control (power, HDD, activity, alerts, heartbeat)
  • IPMI over LAN
  • Serial Over LAN
  • Proxy server support
  • LAN messaging and alerting
  • Text console redirection over LAN
  • VLAN support
  • Enhanced authentication and encryption algorithms (RMCP+, SHA-1, AES)
  • Local update of BMC firmware
  • Firmware firewall
  • Support for IPMI v2.0 compliant management software (e.g., xCAT)
  • Other mandatory and optional IPMI BMC functionsThe BMC alerts IBM Director to anomalous environmental factors, such as voltage and thermal conditions—even if the server has failed.The IBM Remote Supervisor Adapter II provides additional systems management capabilities, including:
    • Graphical console redirection over LAN
    • Web-based out-of-band control
    • Windows “blue screen” capture
    • Remote virtual floppy and CD-ROM
    • High-speed remote redirection of PCI video, keyboard and mouse
    • SSL (Secure Socket Layer) and LDAP (Lightweight Directory Access Protocol) supportAutomatic Server Restart (ASR) helps reduce downtime by restarting the server automatically in the event of a system lockup. ASR technology is a combination of hardware circuitry tied into the server’s system reset function and a device driver. As long as the server continues running, the ASR watchdog timer will keep being reset, but if the operating system crashes or the hardware freezes somehow the ASR software will be unable to reset the hardware timer. If the timer is not reset within five minutes, it automatically triggers the ASR hardware, which immediately restarts the server (and logs an ASR event with IBM Director). These features are designed so that no more than five minutes can pass before the server is restarted.Wake on LAN permits the server to be remotely powered on if it has been shut off. Once powered up, the server can be controlled across the network, using the Preboot Execution Environment (PXE).Like Wake on LAN, PXE is system firmware. It enables software such as the optional IBM Remote Deployment Manager to take control of a system before the BIOS, operating system or applications are loaded (using Wake on LAN/PXE) and lets an administrator perform many low-level tasks remotely that would otherwise require a visit to each system. These tasks may include such things as formatting a hard disk drive, updating system firmware, or deploying a Windows or Linux operating system.

Please see the Legal Information section for important notices and information.

Key Options

Text and Graphical Console Redirection support allows the administrator to remotely view system text messages and graphics over serial or LAN.

Predictive Failure Analysis (PFA) is designed to allow the x3850 M2/x3950 M2 to detect impending failure of supported components (processors, memory, PCI-E slots, VRMs, power supplies, fans, and hard disk drives) before actual failure, and alert the administrator through IBM Director. This gives you the ability to replace the failing component before it fails, resulting in increased uptime.

IBM Director software for advanced workgroup management is included with the eX4 servers. IBM Director comes with a portfolio of tools, including Management Processor Assistant, Rack Manager, RAID Manager, Update Assistant and Software Distribution. IBM Systems Director Active Energy Manager for x86, System Availability (a no-charge download) and Capacity Manager (sold separately) are available as add-ons for additional server management and increased availability. IBM Director provides a single uniform graphical interface for all of these systems management functions.

IBM Director enables you to customize thresholds and monitor system components (for things like temperature, voltage regulation, etc.) to help maximize uptime.

IBM developed IBM Systems Director Active Energy Manager for x86 to put control of system power-saving features at the fingertips of administrators. Active Energy Manager is a combination of hardware and software designed to take advantage of new features, such as monitoring power usage and balancing the performance of the system according to available power input. It provides the ability to plan and predict power consumption based on your hardware configuration. It also helps enable you to reduce the infrastructure required for redundancy, by using fewer servers on smaller power feeds and potentially lowering your overall data center support costs. It does this by inventorying all components, then adding up the total power draw and tracking the usage.

IBM options for System x servers help you take your servers to a

higher level

You can rely on System x options to supply a complete solution for your business needs. Options help you create an optimized server system to meet your data protection, storage and availability needs. Every IBM option is designed and tested for peak performance and flexibility, helping to maximize your return on investment. The combination of System x servers and options lets you keep your fingers on the pulse of your e-business.

Processors — The Intel Xeon MP processor provides high clock rates, dual- or quad-cores, 64- bit extensions, a large cache and advanced features for availability and manageability. Large cache size, combined with a fast 1066MHz front-side bus, reduces memory latency and facilitates the movement of data through the processor and I/O devices. (Note: System performance depends not only on the number of processors in the server but also on the power and functionality of each processor.) Adding a second, third, or fourth processor may be a cost- effective way to achieve significant performance improvements.

Memory — Memory is a significant factor in systems application performance. Adding more memory to a System x server is one of the most effective ways to increase application performance. For best performance in a server with dual-core processors, there should be twice as much memory available as for a server using single-core processors. A server with quad- core processors should have twice as much memory as a server using dual-core processors. The eX4 servers take memory upgrades in pairs and provide two-way interleaving.

Hard Disk Drives — IBM hard disk drives help you improve the transaction and cost performance of your System x servers. The choice of hard disk drives can be a critical aspect of maximizing the I/O throughput of the system. 2.5-inch SAS hard disk drives are available for the eX4 servers with capacities up to 146.8GB apiece at 10,000 RPMs, or up to 73.4GB apiece at 15,000 RPM.

Remote Supervisor Adapter II — The x3850 M2 and x3950 M2 include a plethora of systems management features built-in. The Remote Supervisor Adapter II not only offers powerful new features, it does so without taking up a valuable PCI-E adapter slot, instead using a dedicated PCI-X slot on the motherboard.

ServeRAID Controllers — System x servers using ServeRAID technology allow companies to build a reliable foundation for business-critical computing. IBM ServeRAID technology allows an array consisting of multiple physical hard disk drives to be treated as one logical drive. ServeRAID technology also allows data to be stored redundantly, across multiple hard disk drives— enhancing both the integrity and the availability of the data. SAS and SATA ServeRAID controllers offer enhanced performance due to onboard processors and cache. Because IBM ServeRAID controllers can help significantly improve data transfer rates, this technology is extremely effective when implementing demanding, transaction-oriented applications. By employing the advanced fault tolerance of IBM ServeRAID technology, companies can

effectively implement networked business systems that require large amounts of storage space for data and applications that must be available for their businesses to continue operating.

The optional integrated ServeRAID-MR10k SAS/SATA controller offers enhanced performance over the integrated LSI 1078 SAS controller, 256MB of battery-backed cache memory, and supports seven RAID levels: 0 (striping), 1 (mirroring), 10 (mirroring and striping), 5 (striping with parity), and 6 (striping with double parity), 50 (striping with parity across multiple arrays) and 60 (striping with double parity across multiple arrays). Note: RAID-50 and -60 require external storage, due to the minimum requirement of six or eight drives, respectively.

External SAN, NAS and direct-attach storage is available using one of several IBM System StorageTM and TotalStorageTM host bus adapters.

The IBM TotalStorage DS4000, DS6000, and DS8000 series, as well as the System Storage DS4000, N3000, N5000, and N7000 series, comprise a powerful and broad shared storage family with integrated management software designed to meet midrange and enterprise needs.
