Hi.
We have disk 2105 - F20 with 5,2 tera of storage and 4 Giga cache size by
cluster
we want to come to 8 Giga in every cluster but the increase of Cache
Storage is very expensive...
Now, my chief says to me ... it improves the performance of the machine if we
have the cache doubles ..? how can we quantify it?
IMHO you should consider other possibilities. Assuming you buy cache
from IBM (not from second hand) you will pay a lot. And you still have
quite old DASD box.
It could be reasonable to consider purchase of something newer. You'll
get more cache, faster disks, more powerful controllers... Last but not
least: you will have a *choice*. Competition - that's what can decrease
the price significantly.
