We have a bit of a different problem:
most of the new racks ship with 2 x 30Amp PDUs, and we need to convert a few of
the older R200s with 4 x 20Amp to the 2 x 30Amp PDUs. Last time we tried this,
they seemed practically welded into place…
If you are considering getting the
electricians to pull in the 220v, it might be best to get 30Amp circuits
instead of the 20Amp circuits and convert to those – seems to be the wave
of the future and would probably be easier for any systems you might replace
the R200 with (FAS3070C for example) if you get new cabinets.

Racks
You are probably better off having 220v
power installed in the new facility.
You're going to have a hard time fitting
all the 110v PDUs into the space
of the 220v PDUs since 20Amp @ 220v ~=
40Amp @ 110v. You'll need
two 20Amp @ 110v PDUs for each 20Amp @
220v PDU.
If you have eight 110v circuits for each
rack, it is trivial for the electricians
to combine them into four 220V
circuits. I've had the electricians do this
many times in many data centers over the
years.

Subject: 110v PDUs for NetApp
Racks
We
have an R200 in a 42U NetApp rack with 4ea of the 0U, 220v, 16a PDUs. In
a few months we plan to relocate it to another facility, but they do not have
220v power available, only 110v. Any ideas where we can find 110v PDUs to
replace the NetApp 220v ones? Ideally they would be the same physical
size as the ones currently in the rack. They have to be 0U as the rack is
totally full.
