Support For Advanced Format 4KB Sector Hard-Disk Drives
From the introduction
of PERC 9 family of hardware controller support in Storage Management,
users using legacy 512B sector hard-disk drives can now transition
to Advanced Format 4KB sector hard-disk drives. 4KB sector hard-disk
drives utilize the storage-surface media more efficiently by combining
data that would have been stored in eight 512B sector hard-disk drives
into one sector of 4096B (4KB). This data-combining feature in 4KB
sector hard-disk drives results in improved data efficiency and error
correction capabilities.
Storage Management supports virtual disk creation on 4KB sector hard-disk drives connected to PERC 9 hardware controllers.
NOTE: 4KB sector hard-disk
drives are not supported on controllers prior to PERC 9 family of
hardware controllers. If the 4KB sector hard-disk drive is connected
to any hardware controller prior to PERC 9, the 4KB sector hard-disk
drive is displayed as Unsupported.
When you create a virtual disk using the Advanced Wizard, you can select the physical disk sector from the Sector Size drop-down list. The options available are:
512B
4KB
You cannot use both 4KB sector hard-disk drives and 512B sector hard-disk drives for a virtual disk creation as mixing of hard-disk drive sectors is not allowed in Storage Management.
NOTE: If the system contains any 512e sector hard-disk drives, the 512e sector hard-disk drives are identified/reported as 512B sector hard-disk drives and follows the behavior of the 512B sector hard-disk drives.
