IBM System x3850 X6
IBM Redbooks Product Guide
The IBM® System x3850 X6 server is a four-socket 4U rack-mounted server that represents the sixth
generation of the IBM Enterprise X-Architecture®. It delivers fast application performance, is based on an
agile system design, and is a resilient platform that is needed for mission-critical databases, enterprise
applications, and virtualized environments.
The x3850 X6 packs numerous fault-tolerant and high-availability features into a high-density, 4U
rack-optimized lid-less package that helps reduce the space that is needed to support massive network
computing operations and simplify servicing. The x3850 X6 supports up to four Intel Xeon E7-4800/8800
v2 high-performance processors and up to 6 TB of memory.
Suggested use : mission-critical scalable databases, business analytics, virtualization, enterprise
applications, and cloud applications.
The following figure shows the IBM System x3850 X6.

Did you know?
The x3850 X6 server employs a lid-less design where all serviceable components are front- and
rear-accessible. In addition, each major subsystem is implemented as modular "book" design, such as the
Compute Books and I/O Books. This configuration means that components are easy to upgrade and
service, which translates to greater uptime of applications to your users. The x3850 X6 offers enterprise
scalability and advanced RAS features to support the most demanding mission-critical applications that
require 24x7 operations.
