Dell PowerEdge RAID Controller S140 User’s Guide
Fault tolerance
The following fault tolerance features are available with the PERC S140: If one side of a RAID 1 (mirror) fails, data can be rebuilt by using the physical disk on the other side of the mirror.
- Physical disk failure detection (automatic).
- Virtual disk rebuild using hot spares (automatic, if the hot spare is configured for this feature).
- Parity generation and checking (RAID 5 only).
- Hot-swap manual replacement of a physical disk without rebooting the system (only for systems with a backplane that allows hot-swapping).
If a physical disk in RAID 5 fails, parity data exists on the remaining physical disks, which can be used to restore the data to a new replacement physical disk configured as a hot spare.
If a physical disk fails in RAID 10, the virtual disk remains functional and data is read from the surviving mirrored physical disk(s). A single disk failure in each mirrored set can be sustained, depending on how the mirrored set fails.
