Hi toasters,
does anybody have a clue whats the maximum agitation is, a filer can handle?
Maybe there is an official statement from netapp?!?
The background is, that our facility-department is planing to start some aktivities near to our datacenter and we are afraid of any impact and want to give them some limits.
Thankful for any thoughts!
Regards
Jochen
Hey Jochen, The weakest part in this is most likely the disks, they will start failing more rapidly if they have to deal with shaking grounds etc. Offcourse, most disks can handle shocks up to 3G according to the manufacturers, my experience tells me that when you have movement of a a cm per second, disks will start failing about twice as fast. Keep spares. Heads dont contain any seriously moving parts, so as long as you keep the fans blowing, they tend to be fine as long as your 19" rack is standing up.
My experience comes from a system that was in a datacenter while they were demolishing the building nextdoor, which was attached to the building. Gotta love steel-enforced concrete.
HTH & HAND!

I've had a filer installed in a basement comms room whilst the building around it and all the floors above it were ripped apart and converted for datacenter use. Apart from needing a huge amount of dust blowing out of it when we finally moved into the finished suite everything was peachy.
Hey Chris and Nils,
thanks a lot for sharing your experience. As our facility-dep will only build up a new fundament i think the agitation will stay below those you had to handle.
This gives me a quite good feeling that everything will go smooth.
Kind regards
Jochen

It's Sun, not NetApp, but you get the point.
