We still have a couple hundred addresses defined on our new Shark as 3380's. I'm not sure exactly why, but they are there. I think we had some software that required 3380s at one time, but I don't think we have any now.
I'm curious - what would be the benefit of getting off of the 3380s? I think
that the larger track size might allow a little more data per track, but other
than that, why would having 3380s be a problem?
The benefits of getting off 3380s:
- adressablility. Nowadays disk adresses occupy vast majority of
addressing space. I know datacenters where mod-27 and even mod-54 was
the only ay to address all the dasd box space.
- consistency. Life is much easier when having only one geometry, isn't it?
- convenience. AFAIK the largest 3380 model is approx 1GB. So,
relatively average size datasets have to be multi-volume.
- limits. Large datasets can reach 59-vol limit.
Of course the above does not apply to datacenter with 6MIPS CPC, OS/390
2.6, 3480 drives for backup and 330GB of dasd. We call such datacenters
as palliative: you can't cure them, but you can buoy them up.
