2.7 Display RAID Set Information
Scroll to the Display RAID Set Information option and press
ENT
. Select the RAID set desired,
and the RAID set information will be displayed. Scroll through the available options to see
RAID Set Name, Total Capacity, Free Capacity, Number of Member Disks, Min. Member Disk
Capacity and RAIDSet State.
3. Volume Set Function (C)
A volume set is seen by the host system as a single logical device, and is organized in a RAID
level with one or more physical disks. RAID level refers to the level of data performance and
protection of a Volume Set. A Volume Set capacity can consume all or a portion of the disk
capacity available in a RAID Set, and multiple Volume Sets can exist on a group of disks in a
RAID Set. All Volume Sets created in a specified RAID Set will reside on all the physical disks in
the RAID Set, and the data spread evenly across all the disks in the RAID Set. To enter a Volume
Set Function, press
ENT
to enter the main menu. Scroll to select the Volume Set Functions
option and then press
ENT
to enter further submenus.
3.1 Create RAID Volume Set
The volume set attributes screen shows
the volume set default configuration value
that is currently being configured. These
attributes are:
Capacity
RAID Level
Stripe Size
Cache Mode
Volume Name (number)
Scroll to select attribute to modify and
Press
ENT
to select the desired attribute
value. The following subsections discuss
each attributes descriptions, and for step
by step instructions, please reference
chapter 4, section 7-
”Using RAID Set and
Volume Set Functions.”
3.1.1 Capacity
Enter the appropriate volume size to fit
your application. Each volume set has a
selected capacity which is less than or
equal to the total capacity of the RAID set
on which it resides.
TERABYTE AND LARGER VOLUMES
Standard SCSI allows for 1 byte Command Descriptor Blocks (CDB), limiting the maximum addressable
storage to TB per lun. If the total usable capacity of the RAIDset exceeds TB, an additional volume
must be defined. On host operating systems supporting extended (1 byte) CDB addressing, The
PlatinumRAID U0 can be set to 1 byte CDB operation to allow up to TB maximum addressable
capacity per LUN. Please see Section .1 of this chapter for more information
