Big "IF", what happens if this server (the SFS containing the DIRC
directories), crashs?  Would it also dump the dataspaces?  If so, you
will need lots of spool space also.

But you shouldn't need additional paging space for a 2 week time
period.  Now, if it was a 2 year time period, then, yes, you will need
it.

Just don't go to a CMS user and Xedit a large (multiple GB) file.  As
you start using virtual memory, your dataspaces will start to be paged
out.  Then you wish you had paging space.  

I forget, on current VM systems, if paging is full, do we still
overflow to spool?  And then we only abend CP when paging is full and
spool is full?

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?
