- Hi all,
-
- The configuration is:
-
- 386-33 ISA, 2 * ST1239A Seagate IDE drives w/ ST08 IDE host adapter,
- Tandberg 3820 SCSI tape w/ ADAPTEC 1542B SCSI host adapter, Tseng Lab ET 4000
- VGA card, AST 4 serial card.
-
- The OS is ISC 2.0.2 w/ standard ADAPTEC driver.
-
- The problem is: Any tape access (read and write) is VERY slow.
- Some other people have a similar configuration, but with SCSI drives instead
- of the IDE ones (please don't flame, I know that SCSI is the better choice, but
- unfortunately the more expensive one). There tape drives are also slow, but
- the above one is at least 10-20 times slower.
-
- Any hints ?
-
- How can I figure out if the internal cache of the Tandberg is used, and if not,
- how can I make the tape drive use it ?
-
- Thanx for any hints, peter
-
- PS1: Any information about ISC and SCSI would (probably) help.
-
- PS2: Bitte nicht flamen, ich crossposte.
