About Direct Attached Storage (DAS)

Direct Attached Storage (DAS), also called local storage, is the Gateway's core storage option.

All servers are provided with a single 9 GB boot volume. Users have the option of adding up to six additional direct attached volumes, sized from 9 to 900 GB.

Flexible Direct Attached Storage is presented to a server via SCSI attach, and made possible by the Grid Gateway's SCSI-to-Fibre Channel routing capability. To the server, each volume is indistinguishable from a local SCSI volume. Once configured and

deployed, the volume sizes remain fixed until removed, but you always have the option to add or delete volumes up to the seven-volume limit.

Each volume is both mirrored and backed by a Business Continuance Volume (BCV). The BCVs are local mirror images of active volumes that can be used to perform very fast, non-disruptive backups.
