Supported drive backplane configurations
This information describes the supported drive backplane configurations for the server.
Notes:
1. When mixing drive backplane configurations, you must install all 1.8-inch SSD drive backplanes above
all 2.5-inch drive backplanes.
2. When you mix drive backplane configurations, IMM renumbers the drive bay IDs automatically.
3. For more information about installing drives, see “Installing drives” on page 66.
The following illustrations show the hot-swap drive backplanes that the server supports.
