Looking for decision tree for hardware purchases

I am wandering into an area I rarely play in. I have been asked to provide
a process to help determine what our next hardware purchases should be for
tape and dasd

I am looking for input on what I need to look for when making a decision
between vendors for solutions in the area of tape and dasd for the
mainframe.

I understand capacity, current and growth, ease of migration from one to the
other, speed, replication, de-dup, and compaction.

But what other metrics should I look at or include in the analysis? Are
there RMF reports I should be using or MXG?
Any place with a decent checklist or metrics available?

The mainframe is not as large as the open systems, so the desire is to look
for a "one size fits all" solution.

So for tape - what should I be looking at?

For dasd what should I also be looking at?

Between my data centers I need do to replication (they are about 1500 miles
apart) and back each other up for DASD and hopefully tape as well

Are there any other vendors other than
Fujitsu CS Eternus, IBM TS7700/8700, Luminex, EMC VMAX

So long as I have no need for tape to be shipped, I am thinking tapeless is
an acceptable solution.

Any other guidance is appreciated.

I would want to include some RAS considerations such as:
- mean time to failure;
- mean time to repair;
- availability of local service personnel.

I would add snapshot(such as Flash Copy) capabalities.

Also(this might be obvious ) :
Support for all the (not so) latest and greatest:
zHPF
HyperPAV
EAV

etc...

Yjr kry to any such process is to start with a requirements analysis.
Not just what you need, but the relative importance of each
requirement, including cost and RAS. One question that comes up
immediately is what kinds of replication you need.
