10 IBM BladeCenter JS23 and JS43 Implementation Guide
2.1 Overview of the JS23 and JS43 Express blade
servers
The newest release of the IBM BladeCenter POWER6 processor based blade
family consists of two new models: The JS23 and JS43 Express blade servers.
This new family allows processor scalability starting with a 2 processor (4-core
single wide) blade and adds the ability to upgrade to a 4 processor (8-core) blade
with the addition of a second blade making it a double wide package.
The new blades continue to support AIX, IBM i, and Linux operating systems.
Also supported are the IBM EnergyScale technologies, IBM PowerVM
Virtualization and AltiVec SIMD acceleration functionality.
The optional IBM Systems Director Active Energy Manager (AEM) for POWER
V5.1 and browser-based Integrated Virtualization Manager (IVM) software make
it easier than ever to achieve increased utilization and energy efficiency using the
PowerVM and EnergyScale capabilities of the system.
The IBM BladeCenter JS23/JS43 Express blade servers refresh every major
subsystem to the latest industry-standard functionality. With the energy-efficient
4.2 GHz high performance dual-core, 64-bit POWER6 processors along with the
improved reliability of a SAS disk drive bay supporting multiple disk sizes, the
JS23/JS43 combine leadership performance per watt and enterprise-class
reliability features. The BladeCenter JS23 Express supports up to 64 GB of
DDR2-based memory in eight DIMM slots. The BladeCenter JS43 Express
supports up to 128 GB of DDR2-based memory in sixteen DIMM slots. In
addition to standard support for ECC and IBM Chipkill™ technology designed for
improved memory fault protection, the BladeCenter JS23/JS43 Express also
offers memory running at up to 667 MHz for outstanding performance.
The BladeCenter JS23 Express (7778-23X), BladeCenter JS43 Express
(7778-23X + FC8446), BladeCenter S Chassis (7779-BCS), and BladeCenter H
Chassis (7989-BCH) are part of the Cluster 1350™ portfolio.
The JS23 and JS43 blades can be configured in the IBM eConfigurator similar to
other IBM System p servers.
