NFP Storage Manager 1.1 User’s Manual
76 Chapter 4. Using NFP Storage Manager 1.1
TIP
Size to use is measured in the unit of GB or gigabyte. The smallest
unit depends on the size of the hard disk. The current system will
divide the hard disk space by 20 and take the nearest whole number
as the smallest unit. For example, when the disk total volume is
less than 40 GB, the smallest unit is 1GB. Or when hard disk total
volume is greater than or equal to 40GB and less than 60GB, the
smallest unit will be 2 GB, etc.
Please Note:
While creating non-RAID 1 or non-RAID 5 volume, when system
returns to
Volume Setting page, you will see " Normal” in the State
column for the volume. But when creating RAID 1, RAID 5 or RAID 5
with hot spare volume, the
State column will display Built (Building
percentage: xx%) . This is because when creating RAID 1 or RAID 5
volume, though the volume is created and client is able to perform
save or retrieve function, since the system is still performing
necessary processes in the background (e.g. building RAID 1
consistency or RAID 5 parity) to ensure proper working of the system,
please make sure not to hot-swap the hard disk until the
State column
shows the message: Normal .
Simple
A simple volume must be created in contiguous space of the same
hard disk, and the selected space will be created as independent and
with non-RAID mechanism hard disk. In creating a simple volume,
you can select only one hard disk at a time.
Span
A span volume can be created by combing space from two or more
hard disks. The selected disks will be created as one large,
contiguous volume. The selected space in each hard disk does not
need to be equal in size.
RAID 0
RAID 0 will consider all the selected space as one large hard disk.
Since it will however perform parallel and multiple read/write, thus it
has better performance efficiency than
Simple or Span volume.
