SAS Array Limitations
This section describes the array limitations of the ServeRAID-MR10M
SAS/SATA Controller. These include limitations such as the number of
physical disks supported, the maximum number of disks per controller,
and the maximum number of virtual disks allowed per controller.
Table 1.2
lists the array limitations for the ServeRAID-MR10M controller.

Assumes one Storage Enclosure Processor (SEP) per enclo-
sure.
Note:
The maximum number of hot spares per array is equal to
the maximum number of drives per array.
The controller supports 64-bit logical block addressing (LBA), which
makes it possible to connect a large number of drives to the RAID
controller, directly and through expanders. However, the actual number
of drives that you can attach depends on the limits listed in
rather than by actual RAID volume capacity.
See
Table 1.1
for the minimum number of physical disks required and
the maximum number of physical disks allowed to configure one virtual
disk for each possible RAID level.
