by the space
available on
the disk
volume)
For H-series
RVUs prior to
H06.06 and
G-series
RVUs prior to
G06.29:
Approximately
2 gigabytes
For H06.06 and later H-series
RVUs and G06.29 and later

Approximately
4,000 for
S-series
servers
Approximately
8,000 for
NS-series
servers
The limiting factor is the
number of possible process
control blocks (PCBs) per
processor:
For RVUs G06.00 through
G06.07, the limit was
approximately 1,800.
For RVUs G06.08 through
G06.18 (prior to SPR
T9050AOU), the limit was
