The idea behind RAID

10 is simply based on

the combination of

RAID 0 (Performance)

and RAID 1 (Data Se-

curity). Unlike RAID 4

and RAID 5, there is no

need to calculate par-

ity information. RAID

10 disk arrays offer

good performance and

data security. As in

RAID 0, optimum per-

formance is achieved

in highly sequential

load situations. Identi-

cal to RAID 1, 50% of

the installed capacity

is lost for redundancy.

Any installation or maintenance procedures regarding the ICP Controller are carried out

with the configuration program

GDTSETUP

. The monitoring program

GDTMON

allows a

continuous monitoring and maintenance of the ICP Controller and the connected disk ar-

rays. The GDTMON utility also includes options to replace a defective drive with a new one

(Hot Plug) and is available for most of the operating systems supported by the ICP Con-

trollers. GDTSETUP allows you to set up single disks or complex disk arrays with simple

and user-friendly installation procedures. Little previous knowledge is needed to be able to

use GDTSETUP efficiently. It is only necessary to understand the hierarchy levels in the ICP

Controller firmware (which are the same for both firmware versions: Standard and

RAIDYNE).

For the user's convenience the GDTSETUP program is available in two different variants:

 GDTSETUP loaded from the ICP Controller's Flash-RAM after switching on the computer

 GDTSETUP loaded from disk under MS-DOS.

The header of the GDTSETUP program indicates with a letter after the version number

whether GDTSETUP was loaded from disk or from Flash-RAM:

" for GDTSETUP loaded from the Flash-RAM after switching on the computer

" for GDTSETUP loaded from Disk, i.e., under MS-DOS.

Loading GDTSETUP with <CTRL><G> from the Flash-RAM is very comfortable since no op-

erating system is required to carry out the configuration and setup works.

On the other side, loading GDTSETUP from disk (i.e., under MS-DOS) becomes necessary

for tasks like partitioning or enabling a totally disabled GDT BIOS (which includes

GDTSETUP).
