Richard,
A quick calculation shows that 5.7M blocks x 4K bytes per block is about
22.8GB. That would *seem* to day that you have enough storage to satisfy
your workload's demand.
HOWEVER, I would weigh the cost of providing, say, 30GB of page space vs.
the cost of losing your system -- even once -- to a PGTnnn abend (or
whatever "page space full" is these days)?

Subject: Paging Space Question
The Situation: A small, special purpose VM that is going to have 12 users
accessing data that is contained in DIRC directories that are enabled for
data spaces. These directories will have a total of approximately 5.7
million blocks committed. The processes using them will be most of what is
running in a machine that has 26GB main and 12GB xstore.
The question: Do we need to define sufficient paging space to accommodate
all of the dataspaces plus anything else that may be running, or can we get
by on fewer because the majority of the files in the dataspaces will be in
memory?
Regards,
Richard Schuh
