Supported drive backplane configurations
This information describes the supported drive backplane configurations for the server.
- When mixing drive backplane configurations, you must install all 1.8-inch SSD drive backplanes above all 2.5-inch drive backplanes.
- When you mix drive backplane configurations, IMM renumbers the drive bay IDs automatically.
- For more information about installing drives, see Installing drives.
The following illustrations show the hot-swap drive backplanes that the server supports.
4x2.5-inch NVMe PCIe Gen3 solid state drive backplane rear view: This drive backplane can support up to four 2.5-inch NVMe PCIe solid state drives. The backplane signal cable is attached to the NVMe PCIe Gen3 solid state drive extender adapter. Each NVMe PCIe Gen3 solid state drive extender adapter supports two NVMe PCIe solid state drives.
4x2.5-inch SAS Gen3 12 Gb drive backplane rear view: This drive backplane can support up to four 2.5-inch SAS hard disk drives or four 2.5-inch SATA solid state drives. The backplane power and configuration signals will be supplied from the standard I/O book using cables.
8x1.8-inch solid state 12 Gb drive backplane rear view: Any SAS adapter that you use with this backplane must be capable of driving two internal 4-lane SAS signal connectors. The backplane power and configuration signals will be supplied from the standard I/O book using cables.
You can install a combination of 2.5-inch and 1.8-inch SAS/SATA drive backplanes in the server for the maximum drive capacity. However, any SAS/SATA adapter that you install in the server to control the backplane must be capable of supporting two internal, 4-lane SAS/SATA signal connectors. Also, the server must have a minimum of two compute books with microprocessors and memory installed to support the controller, backplane, and drives.
