All NetApp gear these days (and by these days I mean F700 and later so c. 1997 and beyond) have universal power supplies so they can handle 110 or 220.

For the 3050, each controller, I have 1.9A at 220 and 3.4 at 110. So you can double that for 2 controllers. This is for a typical draw (estimating power costs). Each controller has a worst case (think power up) of 2.04A at 220 and 3.88A at 110.

Hope this helps.

Hi all, I'm setting up a loaner FAS3050c which didn't come with any documentation (working on that issue right now), but am trying to gauge rack space needed and power requirements.

Currently I have a FAS3050 controller (3U) and three DS14mk2 shelves loaded with FC disks. Rounding it out with a 1U Broacade Silkworm 3200 VL2.

Going off specs on Netapp's site and elsewhere it looks like I can expect the controller to use a max of around 6.4 amps, but it's not clear if this is at 110 or 220.

The DS14mk2's have a breakdown depending on the voltage -- 4.4 for 110 and 2.3 for 220.

So, a couple questions:

- Can the controller use 220? - Is the 6.4A rating for 110 or 220?

Any thoughts on a working power configuration would be appreciated.

TIA, Ray
