Model Name shows the model or the manufacturer of the hard disk. Capacity shows the unformatted
capacity of the hard disk.
Status indicates the disk status or disk activity, being one of the following.
The hard disk is a member of a mounted volume which is ready
for data access.
The hard disk is not initialized yet. A no-init disk must be a free
disk, which can be used to create a volume or be assigned as a
hot-spare disk.
The hard disk contains bad sectors.
The hard disk is not mounted and not accessible.
Backup/Archiving Devices
These are either CD/DVD-ROM drives, CD/DVD writers or tape drives. Type indicates what kind of
device it is. Mode indicates the data transfer mode of the storage device interface. Device type could
be CD-ROM, CD-R, CD-RW, DVD-ROM, DVD+R, DVD+RW, DVD-ROM+CD-RW or Tape.
Data Transfer Modes
SATA 1 or SATA 2.
5.2 Creating a Volume
The first thing for the administrator to do with the storage is to create a volume on the hard disks.
Then he or she can share the storage for user access and set security control. To create a volume,
first go to the Volume→Create page. Specify the volume name in the Volume Name field and
choose the volume type (JBOD, RAID 0, RAID 1, RAID 5, RAID 6 or RAID 10). Then choose the hard
disks to be included in the volume. Last, click Apply to submit changes. The progress of volume
creation is shown on the Volume→Information page. Below are the volume types.
Just a Bunch Of Disks.
A JBOD-type volume contains only one hard disk as its member.
RAID level 0 is disk striping only, which distribute data evenly
over multiple disks for better performance. It does not provide
safeguards against failure. RAID level 0 uses two or more hard
disks.
RAID level 1 uses disk mirroring, which provides 100%
duplication of data. It offers high reliability, but doubles storage
cost. RAID level 1 uses two hard disks.
RAID level 5 distributes data and parity bits over multiple disks
