Supported compute nodes

The storage expansion node must be attached to a 1-bay X-Architecture compute node.

Attention
Before you connect a compute node to the storage expansion node, you must make sure that the integrated management module II (IMM2) primary and backup firmware in the compute node is at level ibm_fw_imm2_1aoo34x-1.xx_anyos_noarch or later. If the IMM2 firmware in the compute node is at an earlier level when you connect the compute node to the storage expansion node, the firmware in the storage expansion node will become corrupted and unrecoverable, and you will have to replace the storage expansion node. For information about updating the firmware in the compute node, see the compute node Installation and Service Guide.

Some compute nodes require two installed microprocessors to support connection to the storage expansion node.

As of the date of this publication, the storage expansion node supports the following Flex System compute nodes:

  • x220 (requires two installed microprocessors)
  • x240 (requires two installed microprocessors)
