Hello,
I Must confess that I am not a Storage expert. In our organization we are
working on procuring a new storage box solution. I have been asked to
study and give an opinion on which solution would be perfect for our
mainframe environment.
Could someone give me your advise based on your experience. When selecting
a new storage solution what are the important points that needs to be
looked into the vendors proposal ?
Generally speaking a DASD box is not just a bunch of disks. It is DASD
space + performance + embedded software.
DASD space - obvious
performance - a little bit more complex. There is no single number, like
car velocity. Even cache size should be understood, because vendors have
different way of use of it. Two approaches: compare "guts" (cache, disk
modules, etc.) or compare benchmarks.
embedded software - remote copy, point in time copy, some "obvious"
things like SuperPAV, etc. Unless you have specific requirements all
vendors apply. However their offering differ and it could be important.
And features like Safeguarded copy.
...and zHyperlink. All vendors have FICON32 nowadays, and AFAIK all do
have zHyperlink.
