Supported RAID configurations
All workstation platforms have Intel controllers. Three LSI controllers are supported on some platforms:
●LSI 2308 — HP Z820 Workstations
●LSI
●LSI
Table B-2 RAID configuration details
Configuration |
| Description |
| Controllers |
|
|
|
|
|
RAID 0 | ● | Two drive minimum. | ● | Intel with RSTe or RST |
Integrated striped disk | ● | Improved I/O performance. | ● | LSI 2308 |
array | ● | No fault tolerance. | ● | LSI |
| ||||
| ● | Failure of any disk in the array results in | ● | LSI |
|
| complete data loss. |
|
|
| ● Used to increase disk performance. |
|
| |
|
|
|
|
|
RAID 1 | ● | Two drive maximum. | ● | Intel with RSTe or RST |
Mirrored disk array | ● | 100% redundancy: all data from one drive is | ● | LSI 2308 |
|
| duplicated on a second drive. | ● | LSI |
|
|
| ||
| ● | Can recover from single drive failure. | ● | LSI |
|
|
| ||
| ● Good |
|
| |
|
|
|
|
|
RAID 5 | ● | Three or more drives (for workstations that | ● | Intel with RSTe or RST |
Striped disk array with |
| support three or more hard drives). | ● | LSI |
|
| |||
distributed parity | ● | Fault tolerant and provides I/O performance |
|
|
|
| improvement, especially for |
|
|
|
| applications. |
|
|
| ● Single drive failure does not cause data loss |
|
| |
|
| (performance is compromised until the failed |
|
|
|
| drive is replaced and the array rebuilt). |
|
|
|
|
|
|
|
RAID 10 | ● | Four or more disks (for workstations that support | ● | Intel with RSTe or RST |
Striped and mirrored |
| four or more hard drives). | ● | LSI 2308 |
|
| |||
disk array | ● | Excellent performance. | ● | LSI |
|
|
| ||
| ● | Uses several drives to stripe data, then copies the | ● | LSI |
|
| striped drives to provide redundancy. |
|
|
| ● Offers high data transfer of striped arrays and |
|
| |
|
| increased data accessibility (reads). |
|
|
|
|
|
|
|
RAID 1E | ● | Similar to RAID 10. | ● | LSI 2308 |
● | Must have an odd number of disks. | ● | LSI | |
| ● | Improved read performance. |
