- At last, an item I can comment on! At least, I can provide another
- (more expensive) point on the cartridge backup curve. For roughly
- twice the price of the above (I'm in Canada; I have no access to US
- pricing) you can purchase the SCSI equivalent of Digital's TF85 drive.
- (Sorry, I don't know the scsi product number. The TF85 attaches to
- DEC's (proprietary) DSSI bus; the unit I'm referring to is the same
- with a scsi interface. I have no knowlwdge of suitability under aix
- or sunos/solaris.)
-
- The following is based on my experience with the TF85 on a VAX system
- running VMS. The device is *fast*, both at getting to data and at data
- transfer. Cartridges run about $50 (?? guess only??) and hold 2.6 gigs
- per cartridge. Sustained transfer rate is of the order of 2.9 gig/hour.
- Very high reliability, but at a price.
-
- This followup is purely for the information of readers of this newsgroup.
- I used to manage said vax system, and believe that DEC's product may be
- of interest to some of (certainly not all of) this readership. (There
- are newer faster versions of this product which I have no experience with;
- claims of 6 gig per cartridge using the same media. This is a product
- line; the TF85 level is the bottom of the line.)
-
- Standard disclaimer: I have no interest in DEC other than in my continuing
- role as backup system manager for that vax system. b.
