Service enabled devices
Service enabled devices are hard drives with existing data that can be accessed
by ASC to make use of all key ASC storage services (mirroring, snapshot, etc.),
without any migration/copying, without any modification of data, and with
minimal downtime. Service enabled devices are used to migrate existing drives
into the SAN.
Because service enabled devices are preserved intact, and existing data is not
moved, the devices are not virtualized and cannot be expanded. Service
enabled devices are all maintained in a one-to-one mapping relationship (one
physical disk equals one logical device). Unlike virtual devices, they cannot be
combined or split into multiple logical devices.
