Cluster RAIDYNE® (installed on the GDTx 6 xxRx).
In addition to disk chaining, RAID 0 and RAID 1, RAIDYNE® allows you to install
and control Array Drives of the types RAID 4 (data striping with dedicated parity
drive), RAID 5 (data striping with
distributed parity) and RAID10 (a combination
between RAID 0 and 1). Cluster RAIDYNE® includes also functions to support Mi-
crosoft Cluster Server, Novell Orion and Linux Clustering.
Note: ICP Controllers GDT8523RZ, GDT8543RZ and GDT8563RZ can be upgraded
with the Cluster Module to the corresponding GDT8623RZ, GDT8643RZ and
GDT8663RZ Controllers.
Unlike pure software solutions, e.g., Windows NT, the ICP Controllers a pure hardware RAID
solutions. All ICP Controllers are equipped with a hardware which is particularly well suited
for disk arrays. The ICP Controller firmware uses this hardware with extreme efficiency and
therefore allows you to configure disk arrays that do not load the host computer (whereas
all software-based RAID solutions more or less reduce the overall performance of the host
computer.).
The basic concept of the ICP Controller firmware is strictly modular, and
consequently, in its functioning it appears to the user as a unit construction
system.
