BladeCenter servers
BladeCenter supports the
IBM ^® BladeCenter™ HS20,
a 2-way blade server with up to two
high-performance Intel® Xeon™
Processors; the IBM ^®
BladeCenter™ HS40, a 4-way
blade server with up to four high-
performance Intel Xeon Processors
MP; and the IBM ^®
BladeCenter™ JS20, a PowerPC 970
processor-based server.
The HS20 blade is ideal for applica-
tions such as collaboration, Citrix and
Linux clusters, while the HS40 blade
excels at commerce transactions,
databases and ERP/CRM applica-
tions. The HS20 and HS40 blades
deliver rack-dense solutions for cus-
tomers who demand high reliability
and availability, rapid scalability and
quick installation.
The JS20 (see at a glance chart page
8) delivers a new level of price/
performance for the POWER tech-
nology customer. This blade server
features a 64-bit PowerPC 970
processor, derived from POWER4™
technology. The processor is
enhanced with 162 Single
Instruction/Multiple Data (SIMD)
instructions. Applications in bioinfor-
matics, seismic processing, crash
analysis, digital signal processing
and financial services will often be
able to effectively use these instruc-
tions. They may achieve 20 to 40%
greater throughput because of
increased parallelism in execution.
Applications written for POWER4 and
PowerPC processor-based systems
using the SuSE Linux Enterprise
Server 8 (SLES 8) can be executed
without recompilation on same and
newer models of that processor
family with SLES 8. The exceptions
include, but may not be limited to,
applications compiled using POWER4
or PowerPC specific compiler options
but executed on models other than
POWER4 or PowerPC, respectively, or
applications using undocumented
SLES 8 internal features; or SIMD
instructions which are not available
on POWER4 systems.
The JS20 provides 64-bit Linux sup-
port. This can help customers with
data-intensive applications, enabling
them to simplify programming and
improve application performance.
