"Private" (i.e, for one Array Drive) or "Pool" (i.e., for several Array Drives) Hot Fix Drives.
Online Capacity Expansion. Add one or several new disk drives to an existing Array Drive
to expand its capacity. During the Expansion all data are redundant.
Online RAID Level Migration. Online change of an Array Drive's RAID Level, e.g., from
RAID 0 to RAID 5.
Online Capacity Expansion and RAID Level migration can be performed simultaneously.
Configuration Utility (GDTSETUP) in ROM. Express Setup option to easily setup Array
Drives. Press "CTRL-G" to load GDTSETUP, long before the operating system is booted.
Advanced Multi-Processor RISC Technology.
On-Board 32-Bit RISC CPU. Completely offloads the host CPU.
1, or 2 Narrow & Ultra, or 1, 2, 3 or 5 Wide & Ultra SCSI channels with third generation 32
SCSI RISC processors and an active, software-switchable termination. With the Wide &
Ultra controllers the Low-Byte and High-Byte termination can be switched separately.
For the 1, 2 and 3 channel Wide & Ultra models, the controllers provide both of the fol-
lowing internal connectors:
- a standard 50-pin header for 8 Bit SCSI cables and
- a standard 68-pin receptacle for 16 Bit SCSI cables.
This saves money because no expensive adapters are required.
Can control up to 35 SCSI devices (7 per channel). Hard disks, Removable hard disks, CD-
ROMs, MODs, DAT-drives, streamers, etc.
Full SCSI-2 and SCSI-3 protocol support.
Synchronous data transfer rate per SCSI channel of up to 40MB/sec.
Cache RAM: 4MB, 8MB, 16MB, 32MB, or 64MB.
One standard 72 PIN, 32 Bit or 36 Bit PS/2 SIMM.
FPM (Fast Page Mode) or EDO (Extended Data Out) Dynamic-RAM technology.
With EDO SIMMs increased performance.
Automatic Cache RAM detection.
Optional ECC SIMM (16MB).
Intelligent multi-level cache-algorithm with adaptive delayed write and read ahead func-
tions. This ensures an optimized cache for various load profiles and system require-
ments.
Supports an
Intelligent Fault Bus
(IFB) and the SAF-TE (SCSI Accessed Fault-Tolerant En-
closures) standard.
On-Board PCI 2.x compatible BIOS (Plug & Play).
BIOS, Firmware and GDTSETUP in Flash-RAM. Easy update through floppy disk or BBS-
download.
Full Scatter and Gather support.
