I can't vouch for whether or not a Filer's CPU can be upgraded but I can point something else out....
A 90MHz Pentium has an internal clock speed of 60MHz and a multiplier of 1.5 (60x1.5=90). On motherboards that allow configuration changes there are usually (at least) two jumpers, one for clock speed and another for the multiplier. A Pentium 133 has an internal speed of 66 and a multiplier of 2 (66x2=132 or 133). So, as you can see, a simple chip swap won't work (actually, it might work but without proper mother board support you'd still have a Pentium 90).
Regards,
Paul

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.
Somewhat busy CPU:

Regarding cache age, this unit already has the full 256M of RAM, so we can't address that issue in the conventional way either.
