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 GDT6118RD, GDT6128RD

RAIDYNE-Firmware

(RAID 0, 1, 4, 5, 10) in GDT6518RD, GDT6528RD, GDT6538RD,

GDT6558RD

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:

 Configuration of SCSI and Fibre Channel 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 di-

rectly supported by the operating system.

 EXPRESS and ADVANCED configuration of single disks, or RAID 0, 1, 4, 5 and 10 Host

Drives.

 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:

 Monitoring the disk subsystem performance (KB/sec and I/Os per sec.)

 Monitoring the utilization of the on-board GDT cache

 Online configuration of the GDT cache memory

 Online changes of device parameters

 Online check of the parity information of RAID 4 and RAID 5 Array Drives

 Online capacity expansion of existing Array Drives

 Hot Plug and Hot Fix
