The firmware, the BIOS of the ICP Controller and the configuration program GDTSETUP are
stored in a Flash-RAM on the ICP Controller PCB. The firmware is designed for parallel
processing and it controls all resources of the ICP Controller. This means that the entire
administration of SCSI devices and RAID is exclusively carried out by the ICP Controller.
Thus, the host is significantly offloaded. In addition, this hardware-implemented solution
guarantees the highest achievable security. The controller-BIOS provides a complete PCI
compatible INT13 interface (with 8GB DOS-partition extension) and expands the respective
functions of the system BIOS. It also ensures that operating systems using the INT13 (i.e.
MS-DOS, OS/2) can be booted directly from a SCSI device / RAID Array Drive connected to
the ICP Controller. According to the various product expansion levels of the GDT RP Series,
two different firmware levels are available. Installed upon delivery are the
Standard-Firmware (RAID 0, 1) in GDT6111RP, GDT6121RP, GDT6117RP,
GDT6127RP
RAIDYNE-Firmware (RAID 0, 1, 4, 5, 10) in GDT6511RP, GDT6521RP, GDT6517RP,
GDT6527RP, GDT6537RP, GDT6557RP
A controller originally equipped with the Standard-Firmware can be easily upgraded by the
user with the RAIDYNE-Firmware. The Standard-Firmware offers the RAID Levels 0 and 1.
As controllers have the RAIDYNE-Firmware, RAID Levels 0, 1, 4, 5, 10 and security features
such as
Hot Fix or Hot Plug become available. RAIDYNE is also capable of performing an on-
line capacity expansion of an existing array by adding one ore more new hard disks. During
expansion the array is fully operational. Another feature of RAIDYNE is the online RAID
Level Migration of an existing array, e.g., from RAID 0 to RAID 5.

GDTSETUP is either loadable from the Flash-RAM of the ICP Controller (press <CTRL><G>
after the ICP shows the controller BIOS), or from the command prompt under MS-DOS.
GDTSETUP has a graphical user interface. It provides besides others the following func-
tions:
ƒ
Configuration of SCSI devices connected to the ICP Controller and administrated by
the GDT cache. Devices not controlled by the cache (CD-ROM, DAT, DLT, WORM,
MOD, etc.) are either operated by means of the ASPI interface, or are directly sup-
ported by the operating system.
ƒ
EXPRESS and ADVANCED configuration of single disks, or RAID 0, 1, 4, 5 and 10 Host
Drives.
ƒ
Configuration of the ICP Controller's cache and intelligent fault bus.

The diagnosis program (or simply monitor ) GDTMON (GDT MONitor) is a very flexible soft-
ware tool that offers many different diagnosis and maintenance functions during full-
operation conditions. GDTMON can be used on the fileserver, or remotely from an author-
ized workstation. The main functions of GDTMON are:
ƒ
Monitoring the disk subsystem performance (KB/sec and I/Os per sec. of host-, cache-
and physical drives)
ƒ
Monitoring the utilization of the on-board GDT cache
ƒ
Online configuration of the GDT cache memory
