Drive configurations and numbering
The numbers of storage controllers in tables Table 11-6, Table 11-8, and Table 11-10 are applicable
to all storage controllers except for the RAID-LSI-9460-16i(4G). If you install the
RAID-LSI-9460-16i(4G), only one storage controller is required.
48SFF server
Table 11-6 presents the drive configurations available for the 48SFF server and their compatible
types of storage controllers and NVMe SSD expander modules. Table 11-7 sho
ws drive population
for the 48SFF server.
These drive configurations use the same drive numbering scheme, and drives with the same number
are distinguished by the compute module they reside in, as shown in Figure 11-3.

"N/A" indicates that the compute module is not required but a compute module blank must be
installed.
