Learned a new factoid last night that you should keep in mind. The
power draw will spike when a redundant power supply goes in and out (or
up or down). We managed to brown-out a pdu while swapping a bad ps last
night. Quick way to crash a filer.

Subject: Amperage readings for NetApp 740 head and shelves
My profound thanks to the numerous replies. A little clarification...
This
was for sizing PDUs (Power Distribution Units for you non-Compaq/HP
folks)
for the server racks and not for air conditioning. Compiling all the
information I went with 2.25A@120VAC for the 740 head and 3.0A@120VAC
for
the shelves. I think this will get us close enough where we can balance
the
load sufficiently.
Thanks again!
