Server scalability
This topic provides information about scaling from a 4-socket to an 8-socket
configuration.
The IBM System x3850 X6 and x3950 X6 server uses a direct QPI connection
topology through the midplane to scale from a x3850 X6 (4-socket configuration) to
a x3950 X6 (8-socket configuration) server. The x3950 X6 is achieved by utilizing
the 8-socket chassis, the 8-socket midplane, and the 8-socket shuttle (which comes
in the IBM x3950 X6 4-socket to 8-socket Upgrade Kit), in addition to all of
components used for the x3850 X6. All components are interchangeable between
both the x3850 X6 and the x3950 X6 configurations, except the chassis, mid-planes,
shuttle, and the E7-8xxx v2 microprocessors.
Note: The upgrade of the server from a 4-socket to an 8-socket system must be
performed by a service technician.
The x3950 X6 has two nodes that have their own resources as independent servers.
The server power is distributed through the server midplane. In the x3950 X6
(8-socket) configuration, the power subsystem is divided into two separate nodes,
the top node and the bottom node.
Note:
Power is not shared between the top node and the bottom node of the x3950
X6 configuration. Each node must have its own set of power supplies.

system” on page 135.
FlexNode support
This topic provides information about using FlexNode support to reconfiguring a
multinode 8-socket configuration into two stand-alone 4-socket configurations.
The IBM System x3850 X6 and x3950 X6 server provides support for reconfiguring
a multinode server into two independent, stand-alone servers, known as FlexNode
support (also called Scalable Complex). When FlexNode support is enabled, each
scalable partition can support its own independent operating-system installation.
Each scalable partition has its own local resources as an independent server, and
cannot access the resources or boot the operating system of another stand-alone
server while FlexNode is enabled. The default setting for the x3950 X6 (8-socket)
system is one 8-socket partition. The FlexNode (Scalable Complex) is a feature of
the Integrated Management Module II (IMM2).
Note: The server must be powered off when you enable FlexNode support.
You can manage FlexNode support in two ways:
v Using the IMM2 web interface
v
Using the IMM2 telnet interface
For more information on using the IMM2 web interface and the IMM2 telnet
interface to manage nodes, see “Configuring a multinode system” on page 135.
