1.6.2 SAS Array Limitations
This section describes the array limitations of the ServeRAID-MR10is
controller. These include limitations such as the number of physical
drives 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 controller.
* - Assumes one Storage Enclosure Processor (SEP) per enclosure.
Note: The maximum number of hot spares per array is equal to
the maximum number of drives per array.
The ServeRAID-MR10is controller supports 64-bit logical block
addressing (LBA), which makes it possible to connect a large number of
drives to the controller, directly and through expanders. However, the
actual number of drives that you can attach depends on the limits listed
in
Table 1.2 rather than by actual RAID volume capacity.
The maximum numbers in Table 1.2 depend on how many physical
devices you have connected to the controller. For example, the
maximum number of arrays per controller is equal to the number of
