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.
