As usual, what is reasonable depends.  We use SPACE=(CYL,(500,100)) for
SYSUTx, on disk not VIO.  There does not appear to be any recommendation
in the SMP/E manuals.

Subject: SMP/E: "Reasonable" sizes for SYSUTn?

Hi, All,

Just had a RECEIVE FROMNETWORK job crash SB37-04 on SYSUT4.  The package
being received is HJVA140 and current service.  When I looked at the
SYSUTn (n = [1 - 4]) DDDEFs for the z/OS 1.9 global zone, I saw they all
had UNIT=VIO and SPACE=(3120,(760,760)), apparently "as delivered" with
the z/OS 1.9 ServerPac.  That seems incredibly tiny to me.

Our 1.7 global has SYSUT4 at SPACE=(3120,(3040,3040)), but even that
seems small.  And we didn't SMP/E-install Java on 1.7, so I can't tell
if that size is "reasonable" nowadays.

"Obviously", SYSUT4 needs more that it has, but how much more?  I should
probably try to keep it in VIO, because we don't have a lot of empty
DASD space allocated to the "sandbox".
