Hmm.. was he perhaps referring only to Windows?   On Unix/Linux systems it
is by nature multi CPU aware as it consists of many processes.   (i.e. many
bptm's during a busy backup period)   The kernel will schedule these
multiple process across all CPUs.

AWARE application, it will NOT use more then one CPU during backups. May be
veritas will fix that in V 5.0. so don't waste money, just get as much
single cpu "horse power" as you can, tune up HBA's on host computers and you
should be flying.
