110, 220. Whatever it takes?

I was looking for confirmation about a statement that I recently heard that the best practice for the power supply voltage for a block was 220 volts. And that if 110 volts was used, it was less likely that one power supply could handle the load if one power supply failed. Thank you.

Great question and the supported voltage depends on model.

See here for the spec sheet: http://go.nutanix.com/rs/nutanix/images/Nutanix_Spec_Sheet.pdf

If the model lists 100-240v as acceptable then that means that particular block supports 110v. However, if it lists 180-240v then you will need 208v in order for the block to be supported in a fully redundant manner, meaning that a single PS in the block can support all of the components running within it.

HTH,

as a side note the 3050 series can be full redudant on 110 if you only have 3 nodes in the block.

When we moved into our new cabinets, we went with 208, because we new we were going to be expanding our cluster. I would highly suggest going down the route of running 208 if you plan on moving beyond 3 nodes, as dlink said.
