It varies from system to system but is typically 8-10.

I am aware of that. With the exception of /, /boot and /home which are
on one spindle (actually a hardware mirrored pair) the remaining
filesystems are on separate drives (actually hardware mirrored pairs or
RAID 10 arrays). The largest of the filesystems (four of them) share
a common SAS controller, data channel and external disk array hardware
(HP D2600) so running these in parallel might not be as effective as
they could be.
