Groundbreaking 32/64-bit performance in a 1U server

[Target Customers: Businesses requiring a High-Performance Computing server with 32-bit (and, optionally, 64-bit) capabilities in a space-constrained data center, or Scientific/Technical computing clusters.]

In today’s world, replacing hardware is expensive. The challenge for your customers is to stretch their IT dollars as far as possible. The 2-way IBM ^ 325 lets them do exactly that by offering affordable 32-bit computing today with growth to 64-bit computing when needed. It supports the latest AMD Opteron processors with HyperTransport technology. HyperTransport technology is a high-speed, point-to-point link between the processor and the memory, graphics and I/O controllers that provides outstanding performance by bypassing many key bottlenecks that afflict other processor architectures. Opteron is capable of running both 32-bit and 64-bit software with blazing performance. This provides customers with the flexibility to start with 32-bit applications and grow to 64-bit software over time, without having to replace their servers to do

Standard in the e325 is an integrated systems management controller, optimized for HPC cluster manageability, that enables the user to manage and control the server easily—both locally and remotely. These advanced features help maximize application availability by increasing server uptime, as do hot-swap redundant HDDs and variable speed fans.

With the inclusion of unique manageability features, such as IBM Director and support for the optional IBM Remote Supervisor Adapter II (both planned for Q4/03) the e325 is designed for superior uptime. In addition, IBM Cluster Systems Management can help to reduce the total cost of ownership for cluster environments by streamlining and simplifying the management of large numbers of servers from a single point of control.

If your customer needs leading-edge 32-bit performance in a 1U rack-optimized package, with the added power of 64-bit computing, at a much lower cost than Itanium 2 servers currently offer—and without replacing hardware, the e325 is the ideal system. To illustrate, in the SPECfp_rate2000 benchmark

Actual data transfer speed will vary and is often less than the maximum possible. Gigabit Ethernet transfer speed requires support on both system and server, and appropriate network infrastructure.

GB equals 1,000,000,000 bytes when referring to hard disk drive capacity. Accessible capacity may be less.

posted a floating-point score that was 41% better than that of the Xeon-based HP DL360 G3 server, and at a slightly lower cost. The same e325 score was 63% of that posted by the Itanium 2-based HP rx2600 server, but at one-seventh the cost!

In short: Compared to the x335, the e325 is faster (faster processor for integer operations, faster DDR memory), has greater memory capacity, and it offers the ability to run both 32-bit and 64-bit applications concurrently. When running a 64-bit operating system, the e325 breaks through the “4GB barrier” for memory addressing imposed by 32-bit processors.

Key Features

What’s New? (Compared to the x335)

y AMD Opteron processors with HyperTransport technology, integrated memory controller and

1MB of L2 processor cache

y PC2700 333MHz DDR Chipkill ECC memory (vs. PC2100 266MHz DDR Chipkill ECC

memory for the x335)

y 12GB memory capacity (vs. 8MB for the x335)

y Four USB 1.1 ports (2 front, 2 rear)

y Optional USB floppy drive

High-Performance Opteron Processors

The e325 offers a choice of processors:

y AMD Opteron 240, 242 and 246

The integrated memory controller and 1MB of L2 cache run at the full processor clock rate, not the stepped down rate of the front-side bus (FSB) used in Intel processors. Because of this, the

Opteron 246’s Hyper Transport Tunnel offers peak throughput of 16.0GB per second vs. only

6.4GBps for the (1.5GHz) Itanium’s front-side bus (FSB) — up to 250% faster than Itanium 2, and

a maximum of 4.26GBps for the (3.06GHz) Xeon’s FSB (up to 375% faster than Xeon). Similarly, the maximum aggregate peak memory throughput of the Opteron in a 2-way configuration is

10.6GBps, or up to 250% higher throughput than the peak rate of 4.26GBps provided by the 533MHz FSB of the Intel Xeon processor used in the x335, and up to 24% more than the 8.5GBps of the Itanium 2. I/O performance is equally strong, with the Opteron supporting a peak I/O bandwidth of 12.8GBps, or up to 50% more than the Itanium’s 6.4GBps maximum, and up to 400% of the 3.2GBps of the Xeon.

The e325 ships with one processor, upgradable to two.

DDR Chipkill ECC Memory

The e325 supports up to 12GB4 of memory in six DIMM sockets. It uses registered PC2700 double data rate (DDR) two-way interleaved memory (operating at 333MHz) for faster access, and incorporates the same renowned IBM Chipkill ECC technology used in more expensive IBM servers, for up to 16X better error correction than standard ECC memory.

Memory must be installed in pairs. It is available in 512MB and 1GB (2GB DIMMs are planned).

Large Disk Storage Capacity

The e325 offers a choice of disk storage, supporting up to two internal HDDs:

Hot-swap SCSI

y Ultra320, 10,000 RPMs — 36.4, 73.4 or 146.8GB (293.6GB maximum)

y Ultra320, 15,000 RPMs — 36.4 or 73.4GB (146.8GB)

Fixed IDE

y 7,200 RPM — 40, 60, 80 or 120GB (240GB)

The SCSI drives are hot-swappable, while the IDE drives are not. If the customer needs more storage space, terabyte capacities are possible with external IBM ServeRAID SCSI or IBM FAStT Fibre Channel storage solutions. The Ultra320 SCSI hot-swap drives use the Converged Tray for interchangeability with xSeries systems and FAStT expansion units.

Ultra320 SCSI Controller

The integrated single-channel Ultra320 SCSI controller (LSI 53C1020) allows speeds of up to 320MB per second LVD (low-voltage differential) drives with selectable RAID-1 disk mirroring.

Optional IBM ServeRAID controllers increase the RAID support to nine different levels. For low-cost RAID support of internal IDE drives, use the ATA-133 RAID Controller. Supported RAID controllers include:

y ServeRAID-6M — Ultra320, 2-channel, 256MB battery-backed cache, 133MHz PCI-X

y ServeRAID-6M — Ultra320, 2-channel, 128MB battery-backed cache, 133MHz PCI-X

y ServeRAID-4Lx — Ultra160, 1-channel, 32MB cache, 66MHz PCI

y ATA-133 RAID Controller (IDE) — ATA-133, ATA-100, ATA-66, 2-channel, half-length

The ServeRAID-4 and ServeRAID-6M controllers support external SCSI expansion via the IBM EXP300 Storage Expansion Unit. Each EXP300 adds up to 2.055TB of external Ultra160 SCSI

storage capacity.

The RAID subsystem is closely linked with IBM Director to allow proactive monitoring of the disk subsystem. This feature is used to generate alerts in the event of an impending disk failure or an actual disk failure via Predictive Failure Analysis

across the SCSI bus and supports two internal Ultra320 or Ultra160 SCSI

(PFA).

Dual-Channel Gigabit Ethernet Controller

The e325 includes a two-channel integrated Broadcom BCM5704 Gigabit Ethernet controller for up to 10X higher maximum throughput than the dual 10/100 Ethernet controllers used in some systems. Having integrated controllers saves PCI slots. Optional PCI adapters offering failover and load balancing between them are available for better throughput and system availability.

What’s Hot?

64-bit High-Speed PCI-X Adapter Slots

The e325 has one full-length and one half-length adapter slot, capable of supporting 100MHz 64-bit and 32-bit PCI-X adapters and/or older 64-bit and 32-bit 66MHz and 33MHz PCI adapters. Because the Ultra320 SCSI, dual Gigabit Ethernet and systems management controllers are integrated onto the system board, the two available high-speed adapter slots offer customers a wide degree of latitude in expansion options.

Other New Features

y Four USB 1.1 ports — The flexibility to add more external devices, with two ports in the front

and two in the rear.

y High-resolution video — Up to 1600x1200 resolution, with a color depth of 24 bits at 85Hz

refresh rate, using the ATI Rage XL SVGA video controller.

y USB-attached floppy drive support — Optional drive can be relocated to share among

multiple systems.

y Toolless features — No tools are required for rack installation, cover removal, adapter

retention, power supply replacement or HDD installation/removal.

y Dual processor capability providing symmetrical multiprocessing (SMP) with HyperTransport

technology and integrated memory controller

y Systems management capabilities appropriate for the HPC environment

y Extensive systems management and support features

Dual SMP Processors with HyperTransport Technology

The e325 supports up to two high-performance AMD Opteron processors, allowing customers to upgrade to a second processor as business needs require.

HyperTransport technology is a high-speed, low-latency, point-to-point link, designed to increase the communication speed between circuits. It eliminates a key bottleneck currently caused by the

Data transfer rates depend on many factors and are often less than the maximum possible.

stepped-down front side bus (FSB) used in other system architectures, by accessing memory at the same speed as the processor. This permits the fastest possible access to CPU and memory.

Opteron offers outstanding 32-bit performance using today’s operating systems, and an upgrade path to low-cost 64-bit computing with tomorrow’s 64-bit OSes. With a 64-bit OS, Opteron is even capable of running both 64-bit and 32-bit applications concurrently.

Rack Cable Management and KVM Console Switching

IBM Advanced Connectivity Technology (ACT) is an optional feature that offers many of the same advantages as IBM C2T™ Interconnect cabling (used with x330/x335 servers), plus a few others, across the entire xSeries product line. So now customers can interconnect all of their xSeries and Netfinity servers with one smart cabling architecture. Like C2T Interconnect technology, ACT cabling eliminates the need for one-to-one direct connections between each server and a KVM switch.

Here’s how it works: A USB Conversion Option (UCO) plugs into a USB port of an e325 server and converts the KVM signal to standard CAT5 network cabling signals. An inexpensive CAT5 cable (with RJ-45 connectors on each end) then connects the first server to a UCO or a KCO (KVM Conversion Option, used by xSeries servers) in the next server in the rack. This allows

Short KCO

customers to daisy-chain servers much like the C2T Interconnect feature. Because CAT5 cabling is industry-standard, customers can assemble cables to fit 16 servers to be chained together for common management. If customers have x330/x335 servers in the rack, there is a special 110mm (4”) C2T Conversion Option (CCO) that takes the C2T output and converts it to CAT5 signals for input to one of the CAT5-based switches.

There are two CAT5-based console switches available to manage the servers via the UCO, KCO and CCO kits: Local Console Manager (LCM), a 4-port CAT5 console switch and Remote Console Manager (RCM), a 16-port switch. Each converts the CAT5 signals back to KVM signals for input to a management station.

Using the LCM, up to 16 servers can easily be daisy-chained together (using 16 KCOs) to each o its four CAT5 inputs, enabling the management of up to 64 servers. It provides a single user with local access over all connected systems. The RCM can handle up to 256 servers using any combination of UCO, KCO and CCO kits, and supports a single local user and up to two remote users simultaneously.

Both the LCM and the RCM can accept legacy KVM switch feeds by equipping the switch with one of the KCO options. This makes it easy to incorporate ACT into a traditional KVM environment. The illustration below shows a sample ACT configuration:

on-site. The UCO/KCO allows up to

Remote Console Manager

Legacy NetBAY KVM switch

Up to 42 chained x330/x335 servers per port via CCO

Note: ARI (Analog Rack Interface) = CAT5 port

To achieve the highest video quality (1600x1280 resolution) for local management, the distance from the LCM or RCM to the farthest server on a chain should not exceed 15m (50 ft). For remote access at 1280x1024 resolution, total CAT5 cabling in any chain should be limited to about 10m (32 ft). Longer cables can be used, however video degradation is possible beyond these lengths. For more on ACT cabling, see the ACT Decision Makers’ Guide at

ibm.com/support/docview.wss?uid=psg1MIGR-46120.

Like C2T Interconnect cabling, ACT reduces clutter, simplifies cable management, and reduces cabling costs. Also, having fewer cables improves rack airflow and reduces heat buildup. Plus, while typical KVM cabling limits the management to perhaps 16 servers per switch, ACT can support up to 256 servers using only one RCM. The reduced switch count means that more space is freed up in the side-pocket space of customers’ racks; switch and PDU costs should be greatly reduced; server administration is simplified and there are fewer points of potential failure.

Variable Speed Fans

Eight strategically located fans provide effective system cooling for the e325, from front to back,

throughout the system. This cooling scheme is important because newer, more powerful processors generate a significant amount of heat, and heat needs to be controlled for the system to function properly. The e325 has four system fans, one I/O fan and three fans integrated into the power supply.

The fans automatically adjust speeds in response to changing thermal requirements. 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 put dozens or hundreds in a data center and it makes a big difference!

Drive Bays

The e325 contains three bays. Two bays are hot-swap-capable (when used with SCSI hard disk drives). This enables up to two slim-line (1") 3.5” drives to be installed for a total hot-swap Ultra320 SCSI disk capacity of 293.6GB. (Two fixed IDE drives can be used instead, totaling up to 240GB.) The bays accept drives that use the Converged Tray, for compatibility with other xSeries servers. A 24X bay. (DVD, CD-RW and DVD/CD-RW combo drives are available as options to replace the CD-ROM drive.) If a 1.44MB diskette drive is required, one is available as an option to attach externally to a USB port.

If the customer requires more than two 3.5" HDDs, an optional ServeRAID SCSI controller, or an IBM FAStT Fibre Channel adapter can be installed, along with external storage units.

speed IDE CD-ROM drive is standard in the other (ultraslim half-inch)

Extensive Systems Management Capabilities

The e325 has a high level of systems management capability, including an integrated systems management controller, Alert Standard Format, Automatic Server Restart, Wake-on-LAN support, PXE support, Predictive Failure Analysis, IBM Director and planned support for the optional Remote Supervisor Adapter II. This allows high levels of manageability for customers, without their having to purchase additional adapters or options.

The integrated systems management controller provides local and remote monitoring of the server, including the monitoring of system voltages, temperatures, fans, etc. It also controls the fan speed and the diagnostic LEDs. It features text console redirection over shared NIC or serial port, out-of-band LAN-based management, remote out-of-band alerts, support for command-line interface over shared NIC or serial port, remote access security, out-of-band environmental monitoring and alerting, secure remote power control and system reset over shared NIC or serial port, and others.

Alert Standard Format (ASF) firmware alerts IBM Director to anomalous environmental factors, such as voltage and thermal conditions—even if the server has failed.

Automatic 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). more than five minutes passing before the server is restarted.

Wake on LAN permits the e325 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 2.0).

Variable read rate. Actual playback speed varies and is often less than the maximum possible.

These features are designed to prevent

Like Wake on LAN, PXE is system firmware. It allows systems management software 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 (BIOS or ISMP, for example), or deploying a Windows or Linux operating system.

Predictive Failure Analysis (PFA)

hard disk drives as much as 48 hours before actual failure, and alert the administrator through

IBM Director. This helps give customers the ability to replace the failing component before it fails, resulting in increased uptime.

IBM Director 4.1x (planned for Q4/03), software for advanced workgroup management, is offered at no additional cost for the e325. IBM Director comes with a portfolio of tools for server management and increased availability. IBM Director provides a single uniform graphical interface for all systems management functions.

The combination of IBM Director and the integrated systems management controller enables the customer to customize thresholds and monitor system components (for things like temperature, voltage regulation, etc.) to help maximize uptime.

Plans call for the e325 to also support (effective Q4/03) an optional Remote Supervisor Adapter II for additional systems management capabilities, including:

y Web-based out-of-band control

y Windows “blue screen” capture

y Remote redirection of graphics, keyboard and mouse

y The ability to manage a rack of up to 24 servers from a single Ethernet or serial connection

using one Remote Supervisor Adapter.

Extensive System Support Features

The IBM services and technical support portfolio provides world-class, consistent, high-quality service and support. The e325 server offers a number of tools and services designed to make ownership a positive experience. From the start, IBM programs make it easier for customers to plan for, configure and purchase IBM ^ systems, get them running and keep them running long-term. These programs and features include IBM ServerProven Systems Management, the IBM ^ xSeries and Netfinity Rack Configuration Tool, IBM ServerGuide™, 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 e325 and are officially supported to work together. It is updated frequently with that the latest compatibility information.

IBM Cluster Systems Management (CSM) can help to reduce the total cost of ownership for cluster environments by streamlining and simplifying the management of large numbers of servers from a single point of control. This is of particular value in large data centers or for customers who are running complex high-performance workloads, where managers are constantly challenged to meet ever-changing business demands and improve service levels at the same time that IT budgets are shrinking. As customers evolve from using clusters for single-purpose workloads to employing cluster technology in grids or utility models, CSM can provide a path for growth and enhanced value.

Customers who have existing AIX-based cluster systems can leverage those skills to manage their Linux clusters. System administrators can automate problem determination and recovery, automate repetitive installation and configuration tasks, and monitor and report health information and resource utilization.

CSM is intended primarily for managing clusters of Linux-based xSeries servers or AIX-based

™

pSeries with nonclustered Linux servers. Typically, customers would use IBM Director to manage all-Windows or a mix of Windows and Linux-based xSeries systems in a nonclustered environment. CSM would be the preferred choice for Linux-only nonclustered xSeries servers or clustered Linux/AIX systems (both xSeries and pSeries)—especially in a high-performance computing (HPC) environment.

IBM ^ xSeries and Netfinity Rack Configurator is a downloadable tool that simplifies the often complex chore of configuring a full rack of e325, BladeCenter and xSeries servers and

ensuring that customers have all the cables, power distribution units, KVM (keyboard, video and mouse) switch boxes and other components they need, as well as the proper airflow clearances, electrical circuits and other environmental conditions.

IBM ServerGuide (installed from CD) simplifies the process of installing and configuring e325 servers. ServerGuide goes beyond mere hardware configuration by assisting with the automated installation of the Windows 2000 and 32-bit Windows Server 2003 operating systems, device drivers and other system components, with minimal user intervention. (Selected drivers are also included for support of Novell NetWare, Red Hat Linux and SuSE Linux.) This focus on deployment helps customers reduce both their total cost of ownership and the complexity that administrators and technical personnel face.

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 both xSeries hardware and software, as well as onsite custom services to give customers the level of expertise they require.

Key Options

IBM options for ^ systems let customers take their servers to a higher level

Make sure that customers know they can rely on ^ options to supply a comprehensive solution for their business needs. Options help them create an optimized server system to meet their data protection, storage and availability needs. Every IBM option is designed and tested for peak performance and flexibility, helping to maximize the customer’s return on investment. The combination of ^ systems and options lets customers keep their fingers on the pulse of their e-business.

Processors — The AMD Opteron processor provides power, speed, a large cache, integrated memory controller and HyperTransport Technology. A 1MB L2 cache running at the full processor clock rate combined with an integrated memory controller results in reduced memory latency and speeds 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.) Let customers know that adding a second processor may be a cost-effective way to achieve significant performance improvements. Unlike most processors, adding additional Opteron processors actually increases processor-to-memory bandwidth.

Memory — Memory is a significant factor in application performance. Adding more memory to a server is one of the most effective ways to increase application performance.

Hard Disk Drives — IBM hard disk drives help customers improve the transaction and cost performance of their servers. The choice of drives can be a critical aspect of maximizing the I/O throughput of the system. IBM Ultra320 SCSI hard disk drives are available for the e325 with capacities up to 73.4GB at 15,000 RPMs and up to 146.8GB at 10,000 RPMs. IDE (ATA-100) hard disk drives are available with capacities up to 120GB at 7,200 RPMs.

ServeRAID Controllers — Servers using RAID 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. Optional ServeRAID controllers support nine RAID levels: 0 (striping), 00 (spans multiple arrays), 1 (mirroring), 10 (mirroring and striping), 1E (enhanced mirroring, supporting odd numbers of drives), 1E0 (enhanced mirroring with striping), 5 (striping with parity), 50 (striping across multiple RAID 5 arrays) and 5EE (enhanced RAID 5 with hot-spare drive). (Note: RAID 5EE is an improved version of RAID 5E, with up to 500-700% faster array rebuild times.)

And 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 family of ServeRAID-4 (Ultra160) and ServeRAID-6 (Ultra320) SCSI controllers offers enhanced performance and the ability to add external storage capacity up to 4.1TB (28 x

IBM Confidential 7.

146.8GB) using a ServeRAID-6M and two IBM EXP300 Storage Expansion Units, with industry-leading ServeRAID Manager (RAID management) software.

ATA-133 (IDE) RAID Controller — This two-channel, half-length PCI bus mastering controller supports ATA/133, ATA/100 and ATA/66 HDDs to create an economical, internal storage subsystem using popular RAID levels such as RAID-0, RAID-1, and RAID-10.

Fibre Array Storage Technology (FAStT) — IBM FAStT products are designed to support the large and growing data-storage requirements of business-critical applications. FAStT solutions for the e325 include the FAStT200, FAStT200 HA, FAStT600, FAStT700 and FAStT900 Storage Servers. Because IBM FAStT Fibre Channel solutions can support connectivity distances of up to 10km (6.2 miles) at Fibre Channel rates of up to 2Gbps, companies can more easily configure offsite servers and storage systems to keep critical data available around the clock—even in the event of a catastrophe.

These storage servers are designed to provide highly-available Fibre Channel RAID protected storage that provide the foundation for Storage Area Networks (SANs). FAStT900 storage servers deliver scalability up to 32.8TB. They provide end-to-end Fibre Channel solutions with high-availability fault-tolerant components.

Selling Features

Power and Scalability

As your customer’s business changes and grows, the e325 has the ability to grow with the customer’s requirements, thanks to:

y Up to two Opteron 246 processors with two-way SMP capability, HyperTransport technology

and 1MB of integrated Level 2 cache per processor, to offer outstanding performance capable of tackling the toughest jobs.

y Up to 12GB of high-speed dual data rate (DDR) Chipkill error checking and correcting (ECC)

system memory, if the customer needs to add more users or another application.

y Two available 64-bit 100MHz PCI-X slots help to provide protection from technological

obsolescence, by supporting future high-speed PCI-X adapters (such as 10Gb Ethernet and 10X InfiniBand) that won’t run in older 33MHz and 66MHz PCI slots.

y A high degree of integration that saves valuable adapter slots — Dual Gigabit Ethernet

controllers provide high-speed network communications; an Ultra320 SCSI controller offers RAID-1 mirroring standard; the integrated systems management controller performs sophisticated systems management; and an ATI Rage XL video chip provides high-performance graphics.

y Up to two hard disk drives, which provide either: up to 293.6GB of internal Ultra320 SCSI

hot-swap storage for the operating system and applications, and allow for a RAID-1 mirrored array; or up to 240GB of fixed IDE/ATA-100 storage.

y Up to terabytes of external storage, via optional ServeRAID or FAStT controllers.

Outstanding 32/64-bit price/performance in a rack-dense 1U, 2-way server for HPC applications

y Optional ACT interconnect cabling technology can eliminate hundreds of connectors and

hundreds of feet of KVM cables per rack, while helping to increase reliability and reduce setup time. This saves customers money in terms of KVM cabling, PDUs and KVM switches, as well as

the time necessary to manage all those cables switches. The 1U form factor allows the customer to pack a lot of power in a small data center, while minimizing the floor space cost for all those servers.

y The integrated systems management controller sends hardware alerts to IBM Director,

which in turn notifies the administrator of potential issues.

y Integrated systems management controllers can be linked among systems for multiserver

control, using an optional Remote Supervisor Adapter II. These adapters allow 24 servers to be controlled remotely from one console.

Service

y Chipkill memory is up to 16X12 better than standard ECC memory at correcting memory

errors, which should reduce the downtime due to memory failures.

y The one-year (parts and labor) limited onsite warranty13 (upgradable to three years) gives

your customers peace of mind and greater investment protection.

y Toolless, cover removal provides easy access to upgrades and serviceable parts. This means

less time (and therefore less money) spent servicing the e325. Toolless rails allow e325 servers to be installed more quickly and easily. Similarly, hot-swap, redundant HDDs mean greater system uptime while these components are being serviced.

y The integrated systems management controller provides local systems management, as

well as remote support via a Remote Supervisor Adapter. The integrated systems management controller, which works with IBM Director to help increase system availability for users, enables IBM service personnel to use sophisticated diagnostic tools to resolve problems quickly.

Outstanding 32/64-bit price/performance in a rack-dense 1U, 2-way server for HPC applications

Integrity rx2600: Itanium 2 accesses memory at the FSB speed (400MHz, currently).

e325: Supports 333MHz PC2700 DDR ECC memory with higher performance than PC2100

memory.

Integrity rx2600: Supports only 266MHz PC2100 DDR ECC memory.

e325: The e325 with the Opteron processor can support a peak aggregate memory bandwidth of

10.6GB per second in a 2-way configuration, up to 25% better than that of the Itanium 2.

Integrity rx2600: The peak aggregate memory bandwidth of the Itanium 2 is 8.53GB per second in a system with a 400MHz FSB.

e325: The e325, with the 64-bit Opteron processor, is capable of running either 32-bit or 64-bit software natively, or both at once, at high performance.

Integrity rx2600: Using the 64-bit Xeon processor, the rx2600 is limited to only 64-bit software at high-speed. 32-bit software runs in emulation mode and therefore much slower than the clock rate would indicate.

e325: The Opteron processor can support a peak aggregate I/O bandwidth of 12.8GB per second in a 2-way 2.0GHz configuration, 100% better than that of the Itanium 2.

Integrity rx2600: The peak aggregate I/O bandwidth of the Itanium 2 is 6.4GB per second in a system with a 400MHz FSB.

e325: Models available with either low-cost IDE/ATA or high-performance Ultra320 SCSI drives.

Integrity rx2600: Offers only SCSI models.

e325: The 1U form factor means twice as many servers per rack as the rx2600, and lower data

center floor-space costs in large numbers.

Integrity rx2600: The 2U form factor requires more racks in large quantities.

e325: Includes dual integrated Gigabit Ethernet controllers for high performance without using

any adapter slots.

Integrity rx2600: Includes only one Gb Ethernet controller and one 10/100Mbps controller. Dual Gb requires an extra-cost option and consumes one of the adapter slots.

e325: The shallower depth of the e325 (66cm/26”) simplifies rack cable management and serviceability.

Integrity rx2600: The rx2600 at 68.6cm/26.5” is nearly an inch deeper than the e325.

e325: The e325 offers optional ACT cabling technology. This dramatically simplifies the cabling of

rack-mounted servers and eliminates the need for potentially hundreds of KVM cables per rack of 1U servers and associated PDUs and KVM switches. This can save the customer as much as thousands of dollars per rack over standard KVM cabling, as well as significant administration time. Also, the interconnection can be done without opening the chassis, and a server can be taken offline without changing the wiring.

Integrity rx2600: HP offers a solution that requires an adapter in every rx2600, at a higher cost than the IBM ACT solution. It also requires opening every server to install the adapter, and rewiring the cabling whenever a server is taken offline—which can be a much more time-consuming process.

e325: Offers superior integer performance and most of the floating point performance

of the

rx2600 at a fraction of the price. Price/performance is tremendously better.

Integrity rx2600: The price is several times higher than for the e325 for similarly configured systems.

The Bottom Line

1. Sell speed: Faster memory and front-side bus helps your customers power through the toughest jobs. Integer performance is better than that of the rx2600. FP performance is about 20% lower, but at a much, much lower price.

2. Sell ACT cabling technology: It dramatically simplifies rack KVM cabling and reduces connectors, thereby helping to increase manageability and serviceability and reducing cabling cost and administration time.

Outstanding 32/64-bit price/performance in a rack-dense 1U, 2-way server for HPC applications

3. Sell cost: Dramatically lower system price, plus the option of IDE or SCSI drives make the e325 a tremendous price/performer vs. the rx2600. Half the rack space required means fewer racks are required when large numbers of servers are involved, and less data center floor space.

of memory, 50% more than the Dell.

e325: The e325, with the 64-bit Opteron processor, is capable of running either 32-bit or 64-bit software, or both at once.

PowerEdge 1750: Using the 32-bit Xeon processor, the PE 1750 is limited to only 32-bit software.

e325: Offers integrated RAID-1 mirroring, standard.

PowerEdge 1750: An extra-cost card is required for RAID-1 support.

e325: The Opteron processor can support a peak aggregate I/O bandwidth of 12.8GB per second

in a 2-way 2.0GHz configuration, 4 times that of Xeon.

PowerEdge 1750: The peak aggregate I/O bandwidth is 3.2GB per second.

monitoring.

PowerEdge 1750: Requires an extra-cost ERA/O card for equivalent systems management capabilities.

e325: Models available with either low-cost IDE/ATA or high-performance Ultra320 SCSI drives.

PowerEdge 1750: Offers only SCSI models.

e325: The shallower depth of the e325 (65cm/25.6”) simplifies rack cable management and

serviceability.

PowerEdge 1750: The PE 1750 at 68.6cm/27” is nearly 6% deeper than the e325.

e325: The e325 offers optional ACT cabling technology. This dramatically simplifies the cabling of

rack-mounted servers and eliminates the need for up to hundreds of KVM cables per rack of 1U servers and associated PDUs and KVM switches. This can save the customer as much as thousands of dollars per rack over standard KVM cabling, as well as significant administration time. Also, the interconnection can be done without opening the chassis, and a server can be taken offline without changing the wiring.

PowerEdge 1750: Dell offers nothing equivalent to ACT. The administrator must install many KVM cables, switches and PDUs for a rack full of PE 1750 servers. Whenever a server is taken offline the remaining servers must be rewired—a time-consuming process.

12GB capacity requires a 2-way system using 2GB DIMMs. A uniprocessor system is limited to 8GB of RAM.
