RE: Which Tape Drive?

["Jerry C. Adams" <midrange@xxxxxxxx>]

On our current Model 250 we have 8GB drives - two, mirrored.  We currently
have a 6382 tape cartridge drive.  The backup, which saves *ALLUSR
libraries, runs at night (at 2330). Can't remember how long it takes, but
it's certainly finished by the time I get here (around 0500).  

The proposed system would have three [3] 146GB drives RAID-5.  Now I do
plan/hope to take advantage of the non-QSYS portion of the IFS for requested
process upgrades, but no idea how much space would be involved.  The current
*ALLUSR library sizes would pretty much be the same on the new system.

4MM DAT
--much much slower
--much much less capacity
++cheaper tapes

What tape do you have now?

My preference would be LTO.  I'd also shoot toward getting a drive
that will hold a complete system backup on one tape.  How much DASD
are you looking at?

Perhaps you can get an LTO4 or even LTO3 drive
