6.6.1 Create Disk Volume
FNS-7000B can accommodate four disks at maximum. You can set the disk volume
to the following configurations by clicking on the icons on Create Disk Volume page:
ٛ
a. Single Disk Volume You can create an individual disk volume. In case of
disk crash, all data will be lost.
ٛ
b. RAID 5 Disk Volume Three or more hard disks can be integrated to form
RAID 5 disk volume. Data will be distributed and stored among the disks. If a disk fails,
you can replace a new disk with the damaged one, and the system will restore the data
to the new disk. You can also use three disks for RAID 5 and a fourth disk as a backup
disk. If a disk of RAID 5 volume is damaged, the spare disk can replace that damaged
disk, which enhances server stability and efficiency.
Note: When configuring RAID 5 disk volume, at least 3 disks are required.
ٛ
c. RAID 1 Mirroring Disk Volume Mirroring Disk protects your data by
automatically backing up the contents of one disk onto the second disk of a mirrored pair.
This protects your data if one of the disks fails. However, the storing capacity is equal to
a single disk, as the second disk is used to automatically back up the first one.
ٛ
d. RAID 0 Striping Disk Volume Striping disk combines two or more disks into
one larger disk. It offers the fastest disk access but does not have any protection of your
data if the striped array fails. The disk capacity equals the number of disks in the array
times the size of the smallest disk.
ٛ
e. Linear Disk Volume You can combine two or more disks into one larger
disk. Files will be saved on physical disks sequentially but does not have a disk failure
