Virtual Disk Considerations For PERC S100, S110, S130, And S300 Controllers
The following considerations apply when creating virtual disks:
- Space allocation — When you create a new virtual disk, the PERC S100, PERC S110, PERC S130, and PERC S300 controllers allocate the largest area of free space on the physical disks to the new virtual disk.
- Rebuilding data — If a failed physical disk is used by both redundant and non-redundant virtual disks, only the redundant virtual disks are rebuilt.
NOTE: For information
on controller limitations, see Number Of Physical
Disks Per Virtual Disk.
NOTE: When creating
virtual disks using software RAID controllers, the information related
to the physical disks linked to the virtual disk is enumerated or
displayed on Storage Management after a short delay. This delay in
displaying the information does not cause any functional limitation.
If you are creating partial virtual disks, it is recommended that
you provide Storage Management adequate time between each partial
virtual disk creation process.
NOTE: On software
RAID S110 and S130 controllers, if a physical disk (SATA SSD or HDD)
is removed from a virtual disk and the same physical disk is reinserted
(hot plug) into the virtual disk instantly, within a fraction of a
second, then the virtual disk state is displayed as Ready and the physical disk state is displayed as Online. However, if the same physical disk is reinserted after a short
delay, then the virtual disk state is displayed as Degraded and the physical disk state is displayed as Ready.
NOTE: On software
RAID controllers, virtual disks can be created only with SATA drives.
