EBS RAID configurations

• With Amazon EBS, you can use any of the standard RAID configurations that you can use with a traditional bare metal server, as long as that particular RAID configuration is supported by the operating system for your instance.

  • This is because all RAID is accomplished at the software level.

• For greater I/O performance than you can achieve with a single volume, RAID 0 can stripe multiple volumes together.

• For on-instance redundancy, RAID 1 can mirror two volumes together.
