E About RAID A RAID (Redundant Array of Independent Disks) provides better performance and reliability from combinations of drives than is possible with the same total storage space without RAID. This Appendix describes the various RAID levels supported by Adaptec RAID controllers. The table below shows the number of drives needed and supported for your controller according to RAID level. Array Type RAID 0 RAID 1 RAID 5 RAID 10 RAID 50 Maximum Drives Supported / Minimum Drives Required for Adaptec Controller Models 2410SA 2810SA 2120S/ 2130SLP 21610SA 2020SA/ 2025SA 21610SA 2020ZCR/ 2025ZCR 2200S/ 2230SLP 4 / 2 8 / 2 15 / 2 16 / 2 16 / 2 30 / 2 2 / 2 2/2 2/2 2 / 2 2 / 2 2 / 2 4 / 3 8 / 3 15 / 3 16 / 3 16 / 3 16 / 3 4 / 4 8 / 4 14 / 4 16 / 4 16 / 4 30 / 4 N/A 8 / 6 15 / 6 16 / 6 16 / 6 30 / 6 Note: Select RAID drives of equal capacity and performance.

About RAID
A RAID (Redundant Array of Independent Disks) provides better
performance and reliability from combinations of drives than is
possible with the same total storage space without RAID.
This
Appendix
describes the various RAID levels supported by
Adaptec RAID controllers.
The table below shows the number of drives needed and
supported for your controller according to RAID level.
Note:
Select RAID drives of equal capacity and performance.
Otherwise, the RAID tends to be limited in capacity and
performance to that of the smallest and slowest drive.
Simple Volume
A simple volume consists of a single drive.
