We're still using 42Us - haven't switched over to the tall ones yet.
The datacenters we have are quite large at the moment and should allow for more racks if we need (so it hopefully won't be an issue), if we can keep all that Intel gear out of 'em ;)
Still good to remember - thanks!

Just remember you get one less shelf in one of the tall racks running on
30amp.

We have a bit of a different problem: most of the new racks ship with

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.

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.

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.
