ServeRAID M5110 SAS/SATA Controller Array
Limitations
Specification
Maximum hot spares per controller
Maximum spans per virtual disk
Maximum ports
Note:
The maximum number of hot spares per array is equal to
the maximum number of physical 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 the actual RAID volume capacity.
The maximum numbers in
devices you have connected to the controller. For example, the maximum
number of arrays per controller is equal to the number of physical disks
supported by the controller up to the limit of 128 arrays per controller. In
addition, though you can have up to 16 virtual disks per array, and up to
128 arrays per controller, there is a limit of 64 virtual disks per controller.
