[Target Customers: Front-and mid-tier applications requiring high performance, enterprise- class availability and extreme flexibility.]

Today’s data center environment is tougher than ever. Customers are looking to reduce IT cost,

1complexity, space requirements, power consumption and heat output, while increasing flexibility, utilization and manageability. The IBM® BladeCenter® HS20 blade server, combined with the

2various BladeCenter chassis, can help them accomplish all of these goals.

4A single BladeCenter or BladeCenter H chassis supports up to 14 hot-swappable 30mm

HS20 blades in only 7U (BladeCenter) or 9U (BladeCenter H) of rack space. (A rugged 8U

12BladeCenter T chassis supports up to 8 HS20 blades in a NEBS-3/ETSI-compliant

13telecommunications environment.) In addition to the blade servers, these chassis also hold up to four (BladeCenter/BladeCenter T) communication switches, or up to ten switches/bridges

13	(BladeCenter H) internally. Not only can this save significant data center space (and therefore
15	the cost of floor space and rack hardware) compared to 1U servers, it also consolidates
	switches/bridges and cables for reduced complexity and lower cabling costs, and allows clients
16	to manage everything in the solution as one. Using a BladeCenter chassis, up to 84 HS20
	servers (168 processors) can be installed in one industry-standard 42U rack but the value of
17	BladeCenter extends far beyond high density data center environments.
18	Reducing an entire server into as little as .5U of rack space does not mean trading features and
19	capabilities for smaller size. Each HS20 blade server offers features comparable to many 1U
	rack-optimized full-featured servers: Up to two of the latest single- and dual-coreIntel® Xeon®
19	processors, including full-performance/low-power models. The single-coreXeon processor is
	designed with 1MB or 2MB (model-specific) of L2 cache, a leading-edge 800MHz front-side bus
20	(FSB), 64-bit extensions (EM64T) and Hyper-Threading Technology, to help provide
22	customers with the computing power they require to match their business needs and growth.
	The dual-coreXeon processor provides two cores with matching 1MB L2 caches, for increased

22performance at a lower power draw than the single-core version. Both versions of the HS20 support up to 16GB of 400MHz PC2-3200 ECC (Error Checking and Correcting) double data rate II (DDR2) memory (in 4 DIMM slots) with optional Chipkill™ protection, for high performance and reliability. Integrated dual Gigabit Ethernet1 controllers are standard, providing high-speed data transfers and offering load-balancingand failover capabilities. Via optional expansion cards, each blade can connect to additional Ethernet, Myrinet, Fibre Channel, iSCSI, InfiniBand™, and other high-speed communication switches housed in the chassis. Optional 2-port Expansion Cards add additional fabrics to the HS20 server as needed.

All models offer impressive features at an equally impressive price, including up to two Ultra320 SCSI or SAS hard disk drives (model dependent, with RAID-1disk mirroring support. An optional 30mm SCSI Expansion unit connects to a blade (model-dependent) to provide an additional two SCSI HDDs, with hot-swapand enhanced RAID-1Esupport. Moreover, the HS20 is optimized for diskless operation, offering each blade server access to essentially unlimited storage capacity via Fibre Channel or iSCSI.

The various BladeCenter chassis are designed to monitor environmental conditions in the chassis and each blade and send alerts to the administrator. Advanced standard features, such as Predictive Failure Analysis™, light path diagnostics, hot-swap redundant power supplies and blower modules with Calibrated Vectored Cooling™; IPMI 1.5 support, including highly secure remote power on/off; text-console redirect over LAN, a management module (upgradeable to hot-swap/redundant),IBM Director management software and IBM

1Actual 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.
