The ‘Options’ tab displays the current FastCheck Utility settings and allows you to modify
them. In general, the options should be set as shown below:
Special Note: The ASPI Layer version must be 4.60 or later and the DocSTAR
software version must be 2.33 or later.
External RAID Hardware
The External RAID device is setup as a RAID Level 5 device w/a hot-swappable spare.
This means that it uses ‘Striping w/Parity’ and there is an idle drive in place, just in case
one of the other 5 drives fail. When one of the 5 active drives fail, the other 4 can still
provide the data that was present on the failed drive while they rebuild the missing data to
the 6
th
, spare, drive. The External RAID device uses an internal controller board to
communicate with all six IDE (ATA-II) drives, set as Master. All six drives are mounted
into hot-swappable drive carriers. The External RAID device also contains 2 hot-
swappable power supplies and 4 hot-swappable fans. The External RAID device comes
standard with 32MB of on-board memory for performance.
The Host DocSTAR CPU views the External RAID as one large SCSI hard drive.
Therefore, the External RAID requires a SCSI Host Adapter card be installed in the Host
DocSTAR CPU for communication. The External RAID device is an Ultra-Wide SCSI 3
device capable of communicating at up to 40MB/s (in synchronous mode). The External
RAID is shipped with it’s own Adaptec 2930CU SCSI Host Adapter and a High-density 68-
pin ? ?High Density 50-pin SCSI cable. You must install, and connect the External
RAID to, the provided SCSI Host Adapter to avoid cable length and number of SCSI
devices per card issues. Failure to do so may result in data loss or corruption.
