CHAPTER 4: Advanced Hardware Setup

In the following graphic, each letter represents a unique block
of data, and each column represents a separate hard drive.
Drawback
A RAID 5 array is treated as one drive with the capacity of all
but one of the drives added together.
RAID 10 treats the entire array as a single drive with twice the
storage capacity of the smallest drive. So if you have four drives
(350GB, 300GB, 250GB, and 200GB) in a RAID10 array, your
computer recognizes a single drive with 400 GB total capacity.
Preparing your computer for RAID
Setting up RAID on your computer can involve two major steps,
depending on how your computer has been configured.
To prepare your computer for RAID:
1 Configure the RAID arrays. See the Array Manager User
Guide or “Configuring RAID” on page 43.
2 Install the operating system from the Windows disc that
came with your computer.
Important
If your computer came from the factory with RAID already set up, your
computer is ready to use, and you do not need to perform any of these steps.
