Support For Advanced Format 4K Sector Hard-Disk Drives

From the introduction of PERC 9 hardware controller support in Storage Management, users using legacy 512B sector hard-disk drives can now transition to Advanced Format 4K sector hard-disk drives. 4K 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 4K sector hard-disk drives results in improved data efficiency and error correction capabilities.

Storage Management supports virtual disk creation on 4K sector hard-disk drives connected to PERC 9 controllers.

  • 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 4K 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.
