viii BladeCenter T Type 8720 and 8730: Hardware Maintenance Manual and Troubleshooting Guide
Chapter 1. General information
®
The IBM
high-density, high-performance blade server systems developed for
telecommunications network applications and other applications requiring physical
robustness.
The BladeCenter T unit uses blade servers, switches, and other components that
are common to the IBM BladeCenter product line. This common component
strategy makes it ideal for applications in telecommunications networks that need
high levels of computing power and access to common off-the-shelf middleware
packages that are used in IT data centers. The BladeCenter T unit supports up to
eight blade servers and four I/O modules, making it ideally suited for networking
environments that require a large number of high-performance servers in a small
amount of space. The BladeCenter T unit provides common resources that are
shared by the blade servers, such as power, cooling, system management, network
connections, backplane, and I/O (CD-ROM drive and connectors for USB, network
interfaces, and – for blade servers that support the KVM function – keyboard, video,
and mouse).
Performance, ease of use, reliability (NEBS/ETSI compliance), and expansion
capabilities were key considerations during the design of the BladeCenter T system.
These design features make it possible for you to customize the system hardware
to meet your needs today, while providing flexible expansion capabilities for the
future.
