SPARC SPARC
M10-4 M10-4S Description
x If you configure many guest
domains in a system where 16
BBs compose one physical
partition (PPAR), it takes time
to perform binding for the guest
domains.
It approximately takes (the
number of guest domains for
which binding has already been
performed + 1) x 6 + 10 seconds
to perform binding.
Therefore, if there are no
domains for which binding has
been performed, and binding is
performed for the guest
domains one by one through
the ldm bind-domain
command, the required time is
obtained by summing the times
taken to perform binding for all
of them.
Workaround
We recommend that you do
not configure the system with
a single PPAR but divide it
into multiple PPARs and then
configure guest domains in
each PPAR.
Having a configuration above
not only mitigates the
described phenomenon but
also helps improve fault
tolerance.
If a virtual network switch
(vsw) is configured, you can
reduce the time for binding by
half by setting inter-vnet-link
to off. For notes when
inter-vnet-link is set to off, see
Oracle VM Server for SPARC
Administration Guide or Oracle
VM Server for SPARC Release
Notes.
