Chapter 5 RAID Management
5.1 Quick Function
5.1.1 Quick Create
The number of physical drives in the Disk Array determines the RAID levels that
can be implemented with the Raid Set. This feature allows user to create a Raid
Set associated with exactly one Volume Set. User can change the Raid Level,
Capacity, Volume Initialization Mode and Stripe Size. A hot spare can also be
created depending upon the existing configuration.
If the Volume Set size is over 2TB, an option “Greater Two TB Volume Support” will
be automatically provided in the screen as shown in the example below. There are
three options to select: “No”, “64bit LBA”, and “4K Block”).
Greater Two TB Volume Support:
No : Volume Set capacity is set to maximum 2TB.
64bit LBA: This option use 16 bytes CDB instead of 10 bytes. The maximum volume
capacity up to 512TB. For any hard disk drives working in the 4K native mode in the
Raid set, the volume set directly sets and exposes 4KB sector size to the operating
system. This option works on different OS which supports 16 bytes CDB.
Such as: Windows 2003 with SP1 or later / Linux kernel 2.6.x or later
4K Block : Use this option for Windows OS such as Windows 2000, 2003, or XP.
The maximum Volume Set size is 16TB. Just use the Volume as “Basic Disk”. Volume
can’t be used as “Dynamic Disk”; also can’t be used in 512Bytes block service
program.
Tick on the
Confirm The Operation opti on and click on the Submit button in the
Quick Create screen. The Raid Set and Volume Set will start to initialize.
You can use RaidSet Hierarchy feature to view the Volume Set information (Refer to
Section 5.6.1).
