>From the context, I would say that swap in this definition is the
definition of "virtual swap" given in "System Administration Guide:
Devices and File Systems" (and no where else as far as I can tell):
The Solaris OS uses the concept of virtual swap space, a
layer between anonymous memory pages and the physical
storage (or disk-backed swap space) that actually back these
pages. A system's virtual swap space is equal to the sum of
all its physical (disk-backed) swap space plus a portion of
the currently available physical memory.
I've seen confusion on this among many sysadmins and had a short while
ago brought it up without PSARC-EXT on the reply list.
