Setting up RAID
39
RAID 10 (also called
RAID 1+0
or
RAID 1&0
)
contains sets of RAID 1 mirrors acting as drives
within a RAID 0 striping array. With this setup,
the array could survive one drive failure in each
mirror array.
Drawback
A RAID 5 array is treated as one drive with the
capacity all but one of the drives added together.
RAID 10 treats the entire array as a single drive
with the storage capacity of the smallest
drive × 2. So if you have four drives (350 GB,
300 GB, 250 GB, and 200 GB) in a RAID 10 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
three 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 40.
2
Install the operating system.
