For upgrade with additional drives add the following figures per drive:
AC RMS current*

----- ---- ---- ------- -------
9GB/7200rpm: 77.8 22.8 25.33 0.127 0.106
18GB/7200rpm: 97.6 28.6 31.80 0.159 0.132
9GB/10Krpm: 69.4 20.3 22.60 0.113 0.094
* The AC RMS current is the calculated rack AC input current assuming only
one power sequencer is operational. Calculation is based on 0.9 power
factor, 70% power supply efficiency on the A3000 and D1000 power supplies.
** The 3x15 configuration consists of two racks: a 2x7 rack and a 1x8 rack.
For the 2x7 rack power data refer to the 2x7 max configuration.
3. StorEdge A3000 and StorEdge A3500 cold start initial surge current
specification:
Tray level initial surge current specification:
-----------------------------------------------
RSM disk tray, each power supply:
15 A rms or 21 A peak for one line cycle.
StorEdge A3000 controller module, each power supply:
25 A rms or 35 A peak for one line cycle.
StorEdge D1000 disk tray, each power supply:
11 A rms or 22 A peak for one line cycle.
Rack level initial surge current specification:
-----------------------------------------------
StorEdge A3000 (StorEdge A3000 controller with RSM disk tray in 56" rack)
1x5 configuration, per power cord: 120 A rms for one line cycle or 169 A peak.
StorEdge A3500 (StorEdge A3000 controller with D1000 disk tray in 72" rack)
1x2 configuration*, per power cord: 47 A rms for one line cycle or 79 A peak.
1x5 configuration, per power cord: 44 A rms for one line cycle or 88 A peak.
2x7 configuration, per power cord: 72 A rms for one line cycle or 114 A peak.
1x8 configuration, per power cord: 55 A rms for one line cycle or 110 A peak.
* Assume the rack contains only one 1x2 configuration. The A3000 controller and
the two D1000 trays are powered off from one sequenced output.
