Woo hoo! A whole 2.5 GiB? John, you're a wild man :-)
This is one of the primary reasons we mainframers are a bit of an
endangered species. We don't really have any understanding of what's
"big" anymore.
EAV has been announced with a 3390 architecture that supports up to
268,434,453 cylinders or 228,158,547,671,880 bytes per volume! I have no
idea what's the "right" way to calculate disk space these days. Assuming
you get KB by dividing by 1024 and then MB, GB, TB, etc. by dividing by
1000 each, that would be nearly 223TB *per* volume. I don't care which
platform you work with, that's BIG!
Of course, the very first EAV release will establish an arbitrary
per-volume size limit of 223GB so we can iron out the capacity and
performance bottlenecks that will undoubtedly arise from implementation
of larger volumes. After that, expect the maximum per-volume size to
start rising again.
Meanwhile, Cheryl Watson's polling questions in Orlando didn't show very
many people exploiting the largest (54GB) pre-EAV disks. But, the number
is up significantly from when the same question was asked in San Diego.
