Support For
Advanced Format 4KB 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 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 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 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.
