Re: Power requirements for 170

[Larry Bolhuis <lbolhuis@xxxxxxxxxx>]

It should also be noted that these are absolute maximums with every PCI 
and disk slot and full with the highest load devices, and still includes 
a cushion.  Should you plan for this much power? Yes of course, but you 
won't draw anywhere near that during normal operation.  FrankieIII 
consists of three 'towers' turning 56 drives, 8 removable media devices 
all pushed by 8 power supplies. Add to that 6 external tape drives plus 
a small Ethernet switch. All of that runs exactly twice the power shown 
for the 170 with system expansion.

So as usual, YMMV.
