Understanding RAID volumes
Note: HostRAID controllers do not support RAID volumes.
For the ServeRAID-8i SAS controller and ServeRAID-7t SATA controller, the ServeRAID Manager supports the following RAID volume types:
- Simple Volume - a single disk drive or segment;
not redundant.
- Spanned Volume - two or more disk drives or segments
with the same or different capacity, connected end-to-end. A spanned volume
offers no redundancy or performance advantage over a single drive.
- RAID Volume - two or more logical drives with the same
RAID level, connected end-to-end. The logical drives may have the same or
different capacity and are not striped
together; they may be redundant, depending on the RAID level.
Notes:
-
You must create the individual logical drives before you create a RAID Volume. Use
the Configuration wizard to create the logical drives; then, run the Configuration
wizard again to create the RAID Volume.
- When you create a RAID Volume, the ServeRAID Manager replaces the individual logical drives with a single RAID Volume icon in
the Logical devices view; then, it reports the logical drives as deleted in the event viewer.
The event message is normal and does not indicate a loss of data.
