Chapter 1. The System x3950 and System x3950 E server
The IBM
®
System x3950 Type 8878 server is a 3-U
1
-high, high-performance server.
It is ideally suited for networking environments that require superior microprocessor
performance, efficient asset management, flexibility, and large amounts of reliable
data storage.
The System x3950 E server comes without a microprocessor or memory, but you
can install the components to make the System x3950 E server functionally
identical to the System x3950 server. You can interconnect System x3950 and
System x3950 E servers to create multi-node configurations using two, four, or eight
nodes, for up to 32-way operation. A System x3950 server must serve as the
primary node in the multi-node configuration.
Performance, ease of use, reliability, and expansion capabilities were key
considerations in the design of the server. These design features make it possible
for you to customize the system hardware to meet your needs today and provide
flexible expansion capabilities for the future.
The server comes with a limited warranty. For information about the terms of the
warranty and getting service and assistance, see the Warranty and Support
Information document.
The server contains IBM Enterprise X-Architecture
™
technologies, which help
increase performance and reliability. For more information, see “What your server
offers” on page 5 and “Reliability, availability, and serviceability” on page 7.
