Creating an Array With the ArrayConfigU2 Utility
Creating an Array with Custom Setup
Follow these instructions to create an array with ArrayConfigU2:
1
Insert the ArrayConfigU2 diskette in the system’s drive A and
reboot the system. ArrayConfigU2 starts automatically.
2
Select Disk Array Operations from the Main Menu.
3
Select Create New Array from the Disk Array Operations menu.
4
Type an array name and press Enter. The name can be up to 15
characters long and can include spaces and any other printable
characters.
5
Select an array type. Your options are
–
RAID 0
: Data is striped across the disks in a RAID 0 array,
allowing for faster I/O performance than a single disk.
RAID 0 arrays do not store redundant data; if any disk in
the array fails, all data is lost.
–
RAID 1
: Data is mirrored on one pair of disks. If one disk
fails, data is available. The actual data capacity of the array
equals half the available disk space.
–
RAID 5:
The array contains redundant (parity) data distrib-
uted across all disks in the array. If any one disk fails, data
can be reconstructed from the parity information. If a second
disk fails before the array has been reconstructed, all data is
lost. The actual usable data capacity of the array is equal to
one less than the total number of disks. (One disk’s worth of
capacity is needed to hold the parity information.)
–
RAID 0/1
: Data is striped and mirrored on two or more
pairs of disks. If one disk in a pair fails, data is available.
The actual data capacity of the array equals half the total
available disk space.
See the Adaptec CI/O Management Software User’s Guide for more
information on selecting a RAID level.
