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 sections list the supported
SAS/SATA drive backplane configurations, the number of drives that each configuration supports, and
information on connecting the SAS cables.
Notes:
• When you upgrade drive backplane configurations, you must install all 1.8-inch solid state drive
backplanes to the right of all 2.5-inch drive backplanes. All 2.5-inch backplanes must be installed to the
left of all 1.8-inch backplanes.
• The drive bay IDs can vary, depending on the combination of the SAS/SATA drive backplanes installed in
the server (see “Drive IDs” on page 56 for more information).
• The 8x2.5-inch hot-swap drive backplane with controller expander must always be installed in backplane
slots 3 and 4, see “Connecting the SAS cables” on page 64 for more information on cabling.
