Chapter 1. Introduction The IBM BladeCenter JS20 Type 8842, also known as the blade server, is based on the IBM Power Architecture™ technologies. The BladeCenter JS20 Type 8842 is compatible with IBM BladeCenter units. This high-performance blade server is well-suited for networking environments that require outstanding microprocessor performance, efficient memory management, flexibility, and reliable data storage. Notes: 1. In this document, the term BladeCenter unit refers to any IBM BladeCenter, BladeCenter T, or other BladeCenter-class chassis model, except where specifically indicated otherwise. 2. The number of blade servers your BladeCenter unit supports depends on the type of BladeCenter unit. For example, the IBM BladeCenter Type Eserver 8677 supports up to 14 hot-swap blade servers; the BladeCenter T Types 8720 and 8730 support up to 8 hot-swap blade servers. See the documentation that comes with the BladeCenter unit for more information.
