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 must be capable of supporting two internal, 4-lane
SAS/SATA signal connectors. The following illustrations show the supported
SAS/SATA drive backplane configurations:
Note:
1. When upgrading drive backplane configurations, all 1.8-inch SSD drive
backplanes must be installed to the right of all 2.5-inch drive backplanes. All
2.5-inch backplanes installs to the left of all 1.8-inch backplanes.
2. The drive bay IDs can vary, depending on the combination of the SAS/SATA
drive backplanes installed in the server (see “IDs for hot-swap drives” on page
61 for more information).
The following illustration shows the supported backplane configuration that you
can use to support four drives:
This configuration consists of one 4x2.5-inch drive backplane and requires one
SAS signal cable.
The following illustrations show the supported combination of drive backplane
configurations that you can use to support eight drives:
This configuration consists of two 4x2.5-inch drive backplanes and requires two
SAS signal cables.
