JBOD (Linear)
—JBOD lets you combine multiple disks of
mixed capacities into a single logical storage device. The
capacity of the JBOD array is the sum of the total capacities
of the individual component disks (that is, it does not have
the limitation of RAID 1 where you lose some capacity
when using mixed sized disks). JBOD offers no
performance increase compared to the component disks. It
has lower reliability than the component disks, as the failure
of a single disk results, in general, in the failure of the whole
array.
-
RAID 0
—Distributes data across several disks which gives
improved speed and full capacity. All data on all disks will
be lost if any one disk fails.
-
RAID 1
—Uses two disks (mirrored disks) which each store
the same data, so that data is not lost if one disk fails. Total
capacity of the array equals the capacity of a single disk.
-
RAID 5
—Combines three or more disks in a way that
protects data against loss of any one disk.
-
RAID 6
—Combines four or more disks in a way that
protects data against loss of any two disks.

File system:
-
EXT4
—EXT4 is the successor to EXT3 and provides better
performance because the EXT4 file system can support
very large volumes (default).
-
EXT3
—EXT3 is commonly used in the Linux environment.
EXT3 provides reliability file systems with a maximum
capacity support up to 16 terabytes (TB).
•
Encrypt disk volume:
-
No
—Do not encrypt the disk volume (default).
-
Yes
—Encrypt the disk volume using a password.
If you choose yes, the disk volume is encrypted with a password
and provides an extra layer of security against the theft of data in
the event that disks are stolen. File transfer performance to
encrypted volumes is generally lower than non-encrypted
volumes.The default encryption password is the password of the
administrator account.
