Has anyone considered upgrading the CPU on their NetApp product? It's a closed product, so NetApp won't talk about it, but it seems to me that the Pentium 90 in my F230 (66mhz external speed, 90mhz core?) could be replaced with a Pentium 133 with the same 66mhz external speed without any need for jumpers, etc.
My NetApp is in heavy service, so I'm a bit hesitant. Has anyone tried this, or does anyone have a NetApp in light service that they'd like to try this with?
I've searched the listserve archive and don't see any subjects that would seem to have previously addressed this.

Regarding cache age, this unit already has the full 256M of RAM, so we can't address that issue in the conventional way either.
There was a discussion on this topic back in 1997 - here's what Sean O'Malley had to say on the subject. Naturally, the F520 is not the upgrade choice now, it would be the F720.

I seemed to have unintentionally opened a can of worms here in trying to stop people from trying to upgrade to higher clock speed pentiums. The offcially netapp policy is: 1) we don't recommend it as it doesn't provide any performance gain 2) we don't support such modifications - you may be voiding their warranty 3) we discourage this sort of tinkering - the previous note was just mentioning what I saw in the lab, and wasn't encouraging this sort of activity. 4) No such beast has ever gone through QA and you DON'T want to run a configuation with a non-standard nor QA'ed mother board. The offical Sean O'Malley policy is buy a 520...I spent a good three or four months trying to make the pentium boxes go faster and if I had suceeded there would have been an F340. Messing around with the pentium boxes is a waste of time. If you have a real performance problem with any of the pentium based machine the 520 is the answer. Or get another box and split the load.

whilst cleverly sidestepping the question about overclocking your toaster, am i the only person who doesn't think you've got an overstressed machine there? 2s of cache, a CPU that's only half-used and occasional bursts of writes looks like the right machine for the right job, to me. do you have other reasons for believing this machine not to be up to the job?
but i may be saying this because it upset me to have to upgrade an F330 to an F630 running at 3% CPU and 30-40s cache just because i needed all the disc space. that's another grumble, though.

I've got the same problem Tom. My F330 has been a great machine, but I bought the system fully loaded, and now we are finding that 108GB is not enough.
I have a F740 on the ways, with 500GB to start it.
