Volume Shadowing in OpenVMS is a form of host-based Raid level 1. Essentially two or more identical disk volumes are "mirrored" or "shadowed" resulting in a single "shadow set" volume. Any data written to one disk volume is also automatically written to the others. Shadowing within an OpenVMS Cluster is unique in that the various component volumes of the shadow set can be located on different OpenVMS hosts and even in separate geographical locations. The disk volumes which are members of the shadow set can be single direct-attached disks, RAID-0 stripesets on attached storage controllers or even virtual disk volumes on SAN storage arrays. Additionally, OpenVMS supports booting from shadowed system disks for even greater availability.
