No-compromise, truly balanced, 2-socket blade server for

infrastructure, virtualization and enterprise business applications

Suggested uses: Front-end 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’re looking to reduce IT cost,

complexity, space requirements, energy consumption and heat output, while increasing

flexibility, utilization and manageability. Incorporating IBM X-Architecture

™

features, the IBM

BladeCenter

HS22 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 (i.e., up to 14 servers in 7U) does

not mean trading away features and capabilities for smaller size. Each HS22 blade server offers

features comparable to many 1U rack-optimized full-featured servers: The HS22 supports up to

two of the latest high-performance or low-voltage 6-core, 4-core, and 2-core Intel

Xeon

5500

series and 5600 series processors.. The Xeon processors are designed with up to 12MB of

shared cache and leading-edge memory performance (up to 1333MHz, depending on

processor model) to help provide the computing power you require to match your business

needs and growth. The HS22 supports up to 192GB of registered double data rate III (DDR3)

ECC (Error Checking and Correcting) memory in 12 DIMM slots, with optional Chipkill

™

protection

, for high performance and reliability. Selected models are planned for NEBS-3/ETSI-

compliance.

The HS22 offers an option for VMware vSphere Hypervisor (formerly ESXi) preloaded on a

standard USB flash drive. 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.

An integrated dual-port Gigabit Ethernet

controller is standard, providing high-speed data

transfers and offering TOE (TCP Offload Engine) support, load-balancing and failover

capabilities. Via optional expansion cards, each blade can also connect to additional Ethernet,

SAS, Fibre Channel, iSCSI, InfiniBand

™,

and other high-speed communication switches

housed in the chassis. Optional 2-port and 4-port Expansion Cards add additional fabrics to

the HS22 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 HS22 automatically reduces the

processor frequency to maintain acceptable thermal and power levels.

All HS22 models offer impressive features at an equally impressive price, including up to two

hot-swap SAS or SATA hard disk drives or two hot-swap solid-state drives with RAID-

0/1/1E support, and one USB-based internal flash drive (for embedded hypervisor]. Additional

storage is available via the BladeCenter S chassis. Moreover, the HS22 is optimized for

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

capacity via Fibre Channel, SAS, or iSCSI.

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

wide HS22 blades in only 7U (BladeCenter E) or 9U (BladeCenter H) of rack space or up to 12

in the 12U BladeCenter HT high-speed telecommunications chassis. In addition to the blade

servers, these chassis also hold up to 4 switches (BladeCenter E) or up to 10 (BladeCenter H)

or 8 switches/bridges (BladeCenter HT) internally. The BladeCenter S, designed for SMB and

mid-market customers, takes integration and affordability to a new level, combining up to 12

hot-swap SAS/SATA HDDs (with optional SAS card) and up to 6 blade servers and 4

switches. 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 it allows clients to manage

Chipkill protection on the HS22 requires x4 DIMMs; Chipkill protection is not available with x8 DIMMs.

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.
