All netapp gear is auto-ranging with their power supplies. Use 110, Use 208...it all works.
Best practices have told me the thing not to do (at least for an extended duration) is to plug one side in at 110 and the other side in at 208.
When using 110 power, you need twice as many amps. So, 4 x L6-30s (in other worfds, 120 amps at 208) you will need a lot of amps at 110...240 to cover exactly what you removed.
If your original cabinets were not fully loaded, you may be able to reduce total amps.
For instance, if I check: http://www.netapp.com/us/products/storage-systems/fas6000/fas6000-tech-specs... I find for a single head: 100 to 120VAC, 5.6A (typical) 200 to 240VAC, 2.9A (typical) 9.7A (max.) @ 100VAC 4.8A (max.) @ 200VAC
And for a ds14 disk shelf: 100 to 120VAC/4.52A; 200 to 240VAC/2.23A
So, multiply 4.52 * shelves and 5.6 * heads for a rough estimate. That is all TYPICAL amps. Startup amps are usually higher. The shelves also may use more or less power depending on the type of disks involved (10k vs 15k vs SATA etc)

Greetings Toasters,
Please bear with me, I'm not an electrician.
We are constructing a new data center and we are standardizing our racks and the power feeding them. We plan to move some netapp hardware to the new data center, which is currently installed in netapp cabinets where each cabinet is powered by 4 240V 30 amp circuits.
The racks in the new data center will be powered by 6 120V 20 amp circuits each. That is less power than we have in our netapp cabinets, but we can simply put less equipment in the new racks if necessary.
I am pretty sure that this will not cause us any problems. We already have several FAS2050 controller pairs and DS14MK2 disk shelves installed in non-netapp racks plugged into 120V outlets.
Can FAS6040 and FAS3170 heads be plugged into 120V ? (I will double check the hardware specs.)
We could move the netapp cabinets to the new data center, but then we need to reserve floor space for the cabinets and run 240V circuits to them. We would rather use the new standard racks/power.
