everything in the solution as one. Using a BladeCenter E chassis, up to 84 HS22 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.
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 Active Memory
, Predictive Failure Analysis
, light path diagnostics, hot-swap
redundant hard disk drives, power supplies and blower modules with Calibrated Vectored
Cooling
; IPMI 2.0 support, including highly secure remote power control; text-console
redirect over LAN, next-generation BIOS (UEFI), an Advanced Management Module
(upgradeable with a redundant AMM), IBM Systems Director management software including
IBM Systems Director Active Energy Manager™ for x86. Remote Deployment Manager,
and IBM ServerGuide
help maintain system availability with increased uptime.
If you need highly manageable, high-performance computing power in a space- or power-
constrained environment, the HS22 is the ideal system.

Price/Performance
There is an HS22 model to fit all budgets. The HS22 offers a choice of high-performance 6-core/4-
core/2-core Xeon processors with integrated memory controllers, clock rates from 1.6GHz to
3.6GHz, and from 3MB to 12MB of shared cache (processor-specific) of integrated L3 cache. Xeon
5600 series processors offer up to 60% better performance

than the previous-generation 5500
series processors and up to 1500% better performance than the single-core processors of a few
years ago that you may still be using.
Low-voltage processors draw less energy and produce less waste heat than higher-voltage
processors, thus helping to reduce data center energy costs. On a per-core basis, the standard
80W processors are extremely economical, consuming as little as 13.33W per core. Some low-
voltage Xeon processors consume only 10W per core (4-core 40W or 6-core 60W).
Up to 192GB of registered DDR3 ECC memory operates at 800MHz to 1333MHz (depending on
the system configuration), for high performance and wide memory bandwidth.
Run two DIMMs per memory channel at 1333MHz in specific 5600 series processor
configurations
Embedded virtualization (optional on all models) offers extremely high performance, enhanced
security, and a zero-gigabyte HDD footprint. (In other words, no mechanical HDD to fail.)
Optional solid-state drives (SDDs) use only 2W of energy per drive, vs. 7-10W for 2.5-inch HDDs.
This is as much as 80% less energy than a HDD would use (with a corresponding reduction in heat
output).
Low -voltage 1.35V memory draws up to 19% less power than 1.5V DIMMs.
Selected HS22 blade servers are planned for NEBS3/ETSI-compliance and feature long-life
availability. These blades are ideal for telecom or Next Generation Network (NGN) applications
such as IPTV, IP Multimedia Subsystem (IMS) and security.
The extremely high degree of integration in the various BladeCenter chassis reduces the need
for server components, replacing numerous fans, KVM and Ethernet cables, power supplies,
external switches and other components with fewer shared hot-swap/redundant components in the
BladeCenter chassis itself. This integration also can greatly reduce the amount of power
consumed and heat produced, relative to an equivalent number of 1U servers. This can
significantly reduce a data center power bill. The reduced datacenter footprint can also save on
infrastructure cost.
The midplanes used in all chassis provide high-speed blade-to-blade, blade-to-switch-module
and module-to-module communications internally as well as externally. The midplanes used in
the BladeCenter H and BladeCenter HT chassis provide four 10Gb data channels to each blade,
and supports high-speed switch modules, including 4X InfiniBand and 10Gb Ethernet.
The various BladeCenter chassis use ultrahigh efficiency power supplies. Many industry-
standard servers use power supplies that are only 70-80% efficient at converting power from AC
wall current to the DC power used inside servers. BladeCenter power modules are up to 94%
efficient (and meet the 80 Plus
®
Platinum Standard). This helps save even more money, as more
of the power input you are paying for is used for processing, rather than released into the data
center as waste heat that requires even more energy to cool.
BladeCenter also reduces the number of parts required to run the system. Sharing fans,
systems management, floppy devices and media means fewer parts to buy and maintain, and
fewer items that can fail and bring the overall solution down.
