Preface

The x3950 M2 server and x3850 M2 are the System x™ flagship servers and
implement the fourth generation of the IBM® X-Architecture®. They delivers
innovation with enhanced reliability and availability features to enable optimal
performance for databases, enterprise applications, and virtualized
environments.

The x3950 M2 four-socket system is designed for extremely complex,
compute-intensive applications that require four sockets, plus processing power
and large memory support.

The x3950 M2 and x3850 M2 features make the servers ideal for handling
complex, business-critical On Demand Business applications such as database
serving, business intelligence, transaction processing, enterprise resource
planning, collaboration applications, and server consolidation.

Up to four x3950 M2 servers can be connected to form a single-system image
comprising of up to 16 six-core processors, up to 1 TB of high speed memory,
and support for up to 28 PCI Express adapters. The capacity gives you the
ultimate in processing power, ideally suited for very large relational databases.
The x3850 M2 is the equivalent of the x3950 M2 however it can only be used as
a single four-processor node

This IBM Redbooks® publication describes the technical details of the x3950 M2
scalable server and the x3850 M2 server. We explain what the configuration
options are, how 2-node, 3-node, and 4-node complexes are cabled and
implemented, how to install key server operating systems, and what
management tools are available to systems administrators.

Chapter 1. Technical overview

The IBM System x3950 M2 and IBM System x3850 M2 are the IBM System x
flagship systems. They are based on eX4 technology, which is the fourth
generation of IBM X-Architecture. This technology leverages the extensive
research and development by IBM in XA-64e chipset based on the scalable
Intel® Xeon MP system.

2 Planning, Installing, and Managing the IBM System x3950 M2

1.1 IBM eX4-based servers

IBM eX4 technology offers a balanced system design with unique scalability,
reliability, availability, and performance capabilities to take full advantage of Intel’s
latest multi-core processors. By connecting four servers together, the
single-system image can have up to 16 processor sockets (96 cores), up to 128
DIMM sockets and 1 TB of RAM, 28 PCI Express slots, and 34.1 GBps of
memory bandwidth for each 256 GB RAM server. This results in a high-capacity
system with significant processing and I/O performance, and greater power
efficiency.

The two servers based on IBM eX4 technology are:

򐂰 IBM System x3850 M2
򐂰 IBM System x3950 M2

Although they have the same technical specifications and features, the x3850 M2
cannot be used to form a multinode unless you upgrade it to an IBM System
x3950 M2 by adding the ScaleXpander Option Kit, as described in section 1.2,
“Model numbers and scalable upgrade options” on page 9.

1.1.1 Features of the x3950 M2 and x3850 M2 servers

The x3950 M2 and x3850 M2 look very similar, as shown in Figure 1-1.

Front and rear panels

The components and connectors on the front and rear of the system are shown
in Figure 1-2 on page 3 and Figure 1-3 on page 4.

Figure 1-2 Front panel of x3850 M2 and x3950 M2

The front panel of the x3850 M2 and the x3950 M2, as shown in Figure 1-2,
provides easy access to a maximum of four hot-swap 2.5-inch SAS drives,
DVD-ROM, two USB 2.0 ports, an operator information panel with power on/off
button, and LEDs indicating information such as scalability, network activity, and
system errors and warnings.

The scalability LED on an x3950 M2 indicates whether the node (building block in
a scalable system) is participating in a multinode x3950 M2 complex. After each
node has successfully merged with the primary node in a partition, the scalability
LED is lit on all nodes in a partition of a multinode complex.

1.2.4 Scalable upgrade option for x3850 M2

Unlike the x3850 server (based on X3 technology), the x3850 M2 can be
converted to an x3950 M2 through the use of the IBM ScaleXpander Option Kit,
part number 44E4249. After this kit is installed, the x3850 M2 functionally
becomes an x3950 M2, and is therefore able to form part of a multinode complex
comprising of up to four x3950 M2s.

The IBM ScaleXpander Option Kit contains the following items:

򐂰 Scalability cable 3.08m (See Figure 1-6 on page 9.)

򐂰 Larger cable management arm, which replaces the existing arm to allow the

easy installation of the scalability cables. See Figure 1-7 on page 12 and
Figure 1-8 on page 13.
