Host-based Volume Shadowing (HBVS) is Disk Mirroring is RAID Level 1. HBVS is capable of shadowing devices of different geometries, of different block counts (with dissimilar device shadowing; allowing for mixtures of hardware) and—with dynamic volume expansion—of growing volumes on the fly, and HBVS is capable of shadowing/mirroring/raid-1 operations across cluster configurations up to the full span—please see the Cluster SPD for the current supported span; the supported span limit is currently multiple hundreds of kilometers—of a cluster. HBVS can be layered onto controller (hardware) RAID, as well. For information on host-based striping, please see the StorageWorks RAID product.
