Configuring RAID System Easily
The Universal RAID Utility supports the Easy Configuration function allowing configurations such as creating Logical
Drive and making a Hot Spare to be provided in the state where unused Physical Devices are connected to RAID
Controllers.
If you decide the number of Physical Devices used for data storage (or the number of Physical Devices configuring
Logical Drives) and the number of Physical Devices used as Hot Spares among unused Physical Devices connected to
RAID Controllers, the Universal RAID Utility automatically configure the RAID System.
The benefits of configuring a RAID System by using the Easy Configuration are as follows. The Universal RAID Utility
performs the jobs which must be examined and manipulated to configure a RAID System instead.
Allowing a RAID System to be configured only by specifying three items, or a RAID Controller, the number of
Physical Devices used for Logical Drives and the number of Logical Drives to be created.
Allowing the Universal RAID Utility to set all the items associated with Logical Drives (including RAID Level,
Capacity, and Stripe Size) automatically.
Allowing more than one Logical Drive to be created at a time.
Making Dedicated Hot Spares for Logical Drives automatically created by Universal RAID Utility if Physical Devices
are left for Hot Spares.
The maximum number of Hot Spares that can be created is 8 for N8103-109/128/134/135
RAID Controllers.
Easy Configuration will fail if you specify more than 8 Hot Spares.
Procedure of Easy Configuration of RAID System
The following describes the procedure of configuring a RAID System easily.
RAID Viewer
Use [Easy Configuration...] in [Tool] menu.
Step 1
Connect Physical Devices used for Easy Configuration to the RAID Controller at this timing if required. If the
Physical Devices are connected completely, start the RAID Viewer.
Step 2 Click [Easy Configuration...] on the pull-down menu of menu item
[Tool].
Step 3 The [Easy Configuration...] wizard is
started. In step 1/3, select the RAID Controller to be
configured by clicking it. Then click [Next].
In the [RAID Controller] area, RAID Controllers which
do not meet the conditions on Easy Configuration do
not appear.
