1U10 RBOD User’s Manual

The 1U10 RAID requires having a host listed on the system. The purpose is to allow a host to

access the RAID logical volume created. To add a host, go to “System” tab then choose “Host”

from the left hand column; then create a host name and specify its WWN.

4.1.2. RAID Addition

1U10 RBOD supports the following RAID level:

- RAID 0: Striped set without parity/Non-Redundant Array.

It provides improved performance and additional storage but no fault tolerance. It

requires a minimum of 2 disks. The capacity of RAID 0 will be roughly c

+ c

…etc, where c

is the size of each of the drives.

- RAID 1: 1U10 RBOD defines RAID1 as mirrored sets in a striped set. With or without

Spare drives. It provides fault tolerance and improved performance.

It works with either an odd or even number of disks, with a minimum of two disks.

The capacity of RAID 1 will be roughly (c x n)/2 where is the size of the smallest drive

and n is the number of disks.

- RAID 5: Striped set with distributed parity. With or without Spare drives.

Distributed parity requires all drives but one to be present to operate; drive failure

requires replacement, but the array is not destroyed by a single drive failure. It requires a

minimum of 3 disks. The capacity of RAID 5 will be roughly (n-1) x c.

- RAID 6: Striped set with dual distributed parity. With or without Spare drives.

Provides fault tolerance from two drive failures; array continues to operate with up to two

failed drives. It requires a minimum of 4 disks. The capacity of RAID 6 will be roughly

(n-2) x c.

Note: c is the size of the smallest drive and n is the number of disks.

To create a RAID volume, refer to the steps as follow:

1 2 ... 17 18 19 20 21 22 23 24 25 26 27 ... 71 72
