Virtual Tape Storage
1
Virtual tape storage allows the storage space on these hard drives to
appear to the backup application as tape cartridges (DLT or LTO). Data is
stored on the hard drives through an interface that appears as a DX3000
or DX5000 system. This allows backup applications to recognize and
integrate a DX3000/DX5000 system into a data center environment just
like a typical tape library.
The area dedicated to virtual tape storage is set during the initial
configuration of the system and cannot be changed without losing
existing data on the virtual tape cartridges.
Virtual Disk Storage
1
Virtual disk storage allows you to dedicate a certain amount of hard drive
capacity for disk storage. Once the virtual disks are configured and
mapped to either a iSCSI or Fibre Channel port, the virtual disks appear
to the host as a SCSI disk device. This disk device is assigned a drive letter
(example C:) and must be formatted like a standard hard drive. Data can
then be stored and read.
The area dedicated to virtual disk storage is set during the initial
configuration of the system and cannot be changed without losing
existing data on the virtual disk drives.
