4 IBM BladeCenter JS23 and JS43 Implementation Guide
1.1 Highlights of BladeCenter
Blade servers are thin servers that insert into a single rack-mounted chassis
which supplies shared power, cooling, and networking infrastructure. Each server
is an independent server with its own processors, memory, storage, network
controllers, operating system, and applications. Blade server design is optimized
to minimize physical space. Standard rack-mount servers require a number of
power cords and network cables, but in the case of blade servers, blade
enclosures provide these services such as power, cooling, networking for
multiple blade servers, thereby reducing the space and cable requirements. See
Figure 1-1 on page 4 for a computing environment with and without blade
servers.

Blade servers came to market around 2000, initially to meet clients’ needs for
greater ease of administration and increased server density in the data center
environment. When IBM released the IBM BladeCenter in November 2002, it
quickly changed the industry with its modular design. The IBM BladeCenter
provides complete redundancy in a chassis, enables network and storage
integration. IBM BladeCenter has the following strong is ideal for infrastructure
consolidation, virtualization, and demanding applications which require scalable
performance and high memory capacity. The IBM BladeCenter blade server
processors use POWER6 processor technology and has the ability to run AIX,
IBM System i™ , and Linux operating systems simultaneously. Overall IBM
BladeCenter provides a secure, resilient and dynamic infrastructure solution that
helps drive cost down, reduces risk, improves energy efficiency and enhances
flexibility.
Built on the promise of the IBM BladeCenter family of products-easy-to-use,
integrated platforms with a high degree of deployment flexibility, energy
efficiency, scalability and manageability-the BladeCenter JS23 and JS43
Express are the premier blades for 64-bit applications. They represent one of the
