Before moving all our servers out (either retired or to the cloud), we had
on our current UPS:
- A System i 520 and expansion unit with a total of 16 hard drives.
- A Cybernetics SAN with 8 hard drives.
- A Lenovo server with 2 hard drives.
- A Dell server with 2 hard drives.
- Another Dell server with 2 hard drives.
That's 30 hard drives we removed. What's on the UPS /now/ are a few
switches, 2 Meraki firewalls, 2 SFF Linux servers (SSD) for DNS, 2 cable
modems, and 2 desktops. The UPS is at 9% load capacity with 133 minutes
run time available.
With all the excess capacity, we thought it would be beneficial to install
UPS outlets at each desktop location throughout the office area. The
electrician who installed the UPS came in and gave us a quote.
In the quote, he says that the UPS (a Liebert Nfinity) would need 2
additional power supplies (at $2,200 each) installed in order to support
doing this and maintain the redundancy we currently have.
I am not an electrician. He says the UPS now supports 4kva or 19.23 amps.
Is he saying the UPS cannot handle the 11 additional desktops we want to
put on it? That those desktops would draw more than the aforementioned
He called me on the phone and actually recommended /not/ doing it because
this UPS is no longer manufactured, though we can get power supplies and
batteries. He would be glad to sell us a new 10kva UPS at $11,000+.
Once upon a time, before the AS/400 was announced, we had a S/36 and
anticipated going to a S/38 one day. So we initially got a 10kva unit.
When it was retired, the power requirements on the "new" AS/400s were so
much less than the S/38, that we got this UPS at less than half the
capacity. Now he's saying we need to go back to a 10kva unit? For 11
