Is there any way to show actual disk IO operations per second. sysstat shows cifs and nfs ops, but we're wondering how that translates into actual IOps underneath the hood (or is it all hidden away)?

Well, I guess the problem is that there's not one clear definition of "disk IO operation". At what level in the protocol stacks...? A.s.o.

sysstat -x talks about kB/s for the physical devices which is good enough IMO.

Anyway. -x has been there for "ages", can't remember when it appeared in ONTAP but it wasn't recently. You do write IOps as disk IO operations. This may not necessarily be the same as FSops, i.e. operations in the WAFL FS per time unit. That's not shown by sysstat -x AFAIK. Then again it is probably an issue of definition of the term "FSop". I think it would be hard for ppl to understand what it is they're seeing, i.e. what the internal unit "op" really means.
