Thin mirroring and migration
Metro node supports the mirroring of thin volumes and the migration of the thin volumes to different arrays.
During the rebuild of a thin leg, metro node preserves the thin nature of the leg. To do this, metro node issues the SCSI UNMAP command to the arrays that support these commands and writes zeros to the blocks on the arrays that do not support the UNMAP feature. Rebuilds for thin provisioned storage provides you additional information on thin rebuilds.
