RAID levels that can use a hot-spare or standby hot-spare drive
Hot-spare and standby hot-spare drives supply additional protection to a RAID configuration. When you select the RAID level for your configuration, consider the following:
[@more@]| RAID level | Can use a hot spare? | Can use a standby hot spare? |
|---|---|---|
| 0 | No | No |
| 1 | Yes | Yes |
| 1E | Yes | Yes |
| 5 | Yes | Yes |
| 5E * | Yes | Yes |
| 5EE * | Yes | Yes |
| 6 | Yes | No |
| 00 | No | No |
| 10 | Yes | Yes |
| 1E0 | Yes | Yes |
| 50 | Yes | Yes |
| 60 | Yes | No |
* RAID level-5E and RAID level-5EE integrate a distributed hot-spare drive, but also can use traditional hot-spare and standby hot-spare drives. If a physical drive fails in a RAID level-5E or level-5EE logical drive and the configuration includes a hot-spare or standby hot-spare drive, the data is rebuilt on the hot-spare or standby hot-spare drive. A RAID level-5E compression or RAID level-5EE compaction does not occur. If a second physical drive fails in the RAID level-5E or level-5EE logical drive, a data compression or compaction will take place on the distributed hot-spare drive.
