Introduction

The Flex System Storage Expansion Node is a captive-mode storage enclosure that is dedicated to a single compute node in the Flex System Enterprise Chassis.

The storage expansion node is PCIe Generation 3 and SAS 2.1 compliant. It supports up to 12 SAS and SATA 2.5-inch hot-swap hard disk drives and solid-state drives, and it supports JBOD configurations and RAID 0, 1, 5, 6, 10, 50, and 60. Some RAID configurations require a Features on Demand key, an optional 512 MB or 1 GB flash/RAID adapter, or both.

The storage expansion node is supported in an Flex System Enterprise Chassis only, and it must be attached to a 1-bay X-Architecture compute node. For information about supported compute nodes and support requirements, see Supported compute nodes.

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.

The storage expansion node comes with a limited warranty. For information about the terms of the warranty, see the Warranty Information document for your storage expansion node. This document is available on the product Documentation CD.

You can obtain up-to-date information about the storage expansion node at the IBM Systems website.

The storage expansion node might have features that are not described in the documentation that comes with the product. The documentation might be updated occasionally to include information about those features. Technical updates might also be available to provide additional information that is not included in the storage expansion node documentation.
