Uncompromising 2-socket blade server for business-
critical or telecommunications applications

[

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,
complexity, space requirements, power consumption and heat output, while increasing flexibility,
utilization and manageability. The

IBM

®

BladeCenter

®

HS20 blade server

, combined with the

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

BladeCenter T

chassis supports up to

8

HS20 blades in a

NEBS-3/ETSI-compliant

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

HS20

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.
Reducing an entire server into as little as

.5U

of rack space does

not

mean trading features and

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-core

Intel

®

Xeon

®

processors, including full-performance/low-power models. The

single-core

Xeon processor is

designed with

1MB

or

2MB

(model-specific) of

L2

cache, a leading-edge

800MHz

front-side bus

(FSB),

64-bit extensions

(

EM64T

) and

Hyper-Threading Technology

, to help provide

customers with the computing power they require to match their business needs and growth

.

The

dual-core

Xeon processor provides two cores with matching

1MB

L2 caches, for increased

performance 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 Ethernet

1

controllers are standard,

providing high-speed data transfers and offering

load-balancing

and

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-1

disk mirroring support. An

optional 30mm

SCSI Expansion unit

connects to a blade (model-dependent) to provide an

additional two

SCSI HDDs, with

hot-swap

and enhanced

RAID-1E

support. 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

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.
