The Scalable Partition web interface is an extension of the IMM web interface and
is used to create, delete, control, and view scalable partitions. The Scalable
Partition web interface firmware is in the IMM.
A multi-node configuration interconnects multiple servers or multiple partitions.
When two servers with memory expansion module configurations are connected
by EXA cables, each multi-node configuration can have one or more scalable
partitions. Each scalable partition supports an independent operating-system
installation.
The scalable partition uses a single, contiguous memory space and provides access
to all associated adapters and hard disk drives. PCI slot numbering starts with the
primary node and continues with the secondary nodes, in numeric order of the
logical node IDs.
Before you create scalable partitions, read the following information:
v Make sure that all the nodes in the multi-node configuration contain the
following software and hardware:
– The current level of UEFI firmware, SAS UEFI code, IMM firmware, and
FPGA firmware
Note: To check for the latest firmware levels and to download firmware
updates, go to http://www.ibm.com/supportportal/.
– Microprocessors that are the same cache size and type, and the same clock
speed
Note: The nodes can vary in the number of microprocessors and the amount of
memory each contains, above the minimum.
To create a scalable partition, complete the following steps:
1. Connect the EXA cables. See the documentation that comes with your cables for
instructions.
2. Connect all nodes to an ac power source and make sure that they are not
running an operating system.
Note: If the nodes are part of an existing partition, all nodes must be in
Standby mode, which means that the nodes are part of the partition but
