RE: San Francisco Power Outage

2007-07-25 Thread Randy Epstein
It appears that 365 is using the Hytec Continuous Power System [
http://hitec.pageprocessor.nl/p3.php?RubriekID=2016
http://hitec.pageprocessor.nl/p3.php?RubriekID=2016], which is a motor,
generator, flywheel, clutch, and Diesel engine all on the same shaft. They
don't use batteries.
If the flywheels spent their energy before the generators came online, they
don't have the ability to start the generators up without utility power
(unless they purchased the Dark Start option, which is simply extra
batteries).

They claim in the video tour that they do not have any battery systems on
the site.  They rely solely on the flywheels.

Well, the fact still remains that operating a datacenter smack-dab in
the center of some of the most inflated real estate in recent history
is quite a castly endeavor.
I really wouldn't be all that surprised if 365 Main cut some corners
here and there behind the scenes to save costs while saving face.

As it is, they don't have remotely enough power to fill that facility
to capacity, and they've suffered some pretty nasty outages in the
recent past. I'm strongly considering the possibility of completely
moving out of there.

 Testing said combination of UPS and generators? What if it was
 important? I honestly find it hard to believe anyone runs a
 facility like that and people actually *pay* for it.


Sad that the little Telcove DC here in Lancaster, PA, that Level3
bought a few months ago, has weekly full-on generator tests where
100% of the load is transferred to the generator, while apparently
large DCs that are charging premium rates, do not.

Cordially
