Uncompromising 2-socket blade server for business-

critical or telecommunications applications

[Suggested uses: Front-and mid-tier applications requiring high performance, enterprise-class

availability and extreme flexibility and power efficiency.]

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

complexity, space requirements, power consumption and heat output, while increasing flexibility,

utilization and manageability. Incorporating IBM X-Architecture

™

features, the IBM

BladeCenter

HS21 blade server, combined with the various BladeCenter chassis, can help

you accomplish all of these goals.

Reducing an entire server into as little as .5U of rack space does not mean trading away

features and capabilities for smaller size. Each HS21 blade server offers features comparable to

many 1U rack-optimized full-featured servers: The HS21 supports up to two of the latest full-

performance/low-power-draw quad- and dual-core Intel

Xeon

processors. The Xeon

processors are designed with 4MB (dual-core) or 8MB (quad-core) of L2 cache, a leading-edge

1066 or 1333MHz front-side bus (FSB), and 64-bit extensions (EM64T), to help provide the

computing power you require to match your business needs and growth

. The HS21 supports up

to 32GB of 667MHz PC2-5300 Fully Buffered ECC (Error Checking and Correcting) double

data rate II (DDR2) memory in 8 DIMM slots, using the Memory and I/O Expansion Unit, with

optional Chipkill

™

protection, for high performance and reliability. The base HS21 is packaged

into a single 30mm form factor and supports up to 16GB of memory in 4 DIMM slots.

Integrated dual Gigabit Ethernet

controllers are standard, providing high-speed data transfers

and offering TOE (TCP Offload Engine) support, load-balancing and failover capabilities. The

Memory and I/O Expansion Unit provides two additional Gigabit Ethernet controllers (without

TOE support). Via optional expansion cards, each blade can also 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 HS21

server as needed. This blade is designed with power management capability to provide the

maximum uptime possible for your systems. In extended thermal conditions or power

brownouts, rather than shut down completely, or fail, the HS21 automatically reduces the

processor frequency to maintain acceptable thermal and power levels.

All HS21 models offer impressive features at an equally impressive price, including up to two

SAS hard disk drives, with RAID-0 data striping or RAID-1 disk mirroring support. An optional

30mm Storage and I/O Expansion Unit connects to a blade (model-dependent) to provide an

additional three 2.5” SAS HDDs with hot-swap support, optional RAID-5 with battery-backed

cache, and four additional communication ports. Moreover, the HS21 is optimized for

diskless operation, offering each blade server access to essentially unlimited storage capacity

via Fibre Channel or iSCSI.

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

HS21 blades in only 7U (BladeCenter) or 9U (BladeCenter H) of rack space or up to 8 hot-

swappable blades in the rugged 8U BladeCenter T chassis. Plans call for supporting up to 8

HS21 NEBS-3/ETSI-compliant blades in a telecommunications 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 (BladeCenter H) internally. Not only can this save

significant data center space (and therefore 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 to manage everything in the solution as

one. Using a BladeCenter chassis, up to 84 HS21 servers (168 processors) can be installed in

one industry-standard 42U rack but the value of BladeCenter extends far beyond high density

data center environments.

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.
