Battery Power Solutions

Until now I've relied on a relatively piecemeal approach to UPS protection.
Of course, when I started here we only had 2 servers (3 if you count SFTIII
as 2).

Then one battery was "enough". Added more servers, and added more
batteries.

I want my servers to stay up longer and to be more easily manageable via
Powerchute. We've VMed a few serves to reduce the load, but I also want to
increase the power. I am thinking about a Symmetra from APC to be hardwired
into the building. If you have one, what do you think?

If you don't have one, what is your big battery option that you use and
like?


Thanks!

I still like having separate UPSes. We're redesigning our data center,
and in the new design we'll have two racks of equipment: one for servers
and one for networking equipment. I'm going to actually go with two
UPSes in each rack. There will be a Smart-UPS RT 6000VA in each rack
supplying 208V power to most of the equipment and a Smart-UPS 1500VA
supplying 120V power to those few devices which can't take 208V. I'm
also going to have four circuits so that if one circuit for some reason
"pops" that only puts one UPS on battery.

Re: Battery Power Solutions

Our site has evolved; at one stage we had 3 x SmartUPS 2000s needing a
4th 😞

Now we have 2 x Smart UPS 5000s which work really nicely.

These two UPSes have a mains circuit and a generator circuit. We put
the generator in to provide power to the PABX for extended periods of
time (the onsite engineers have been known to kill power to the site
for several hours). A generator was the only viable option for us.

One of the issues that we did have with the multiple UPS running off a
generator was that the generator would only work as hard as it needed
too, so one UPS would be on battery, the other two on generator mains,
then the third would go on to generator battery causing one of the
other UPS to go on to battery due to a power drop - this would happen
for quite a while until they all settled down (5 - 10 minutes).
Cutting down to the 2 5000s solved that issue - they both settle within
about 10 seconds.

We've got 2 per rack now, and it doesn't really scale well, adding a
third, well then you have another PDU for distributing power and so
forth. We're looking at an APC symmetra right now, it's got built in
redunancies all over. For a lot less money you can get a tripplite, but
it doesn't scale power wise unless you go with the next higher unit.

I'd say contact both and see what kind of options/pricing they can give
you just to have more information in your decision process.

Re: Battery Power Solutions

At one location, I've got an APC Symmetra 16Kva Chassis with 8kva of
batteries and power units, another location I have a very large
Eaton/Powerware unit and my others have 2 or 4 APC 1500's at the bottom
of each rack. All locations are generator backed up.

I have to say, the in-line UPS's are excellent. They are costly, but do
the job seamlessly. The Symmetra did require battery replacements about
5 years after installation. But even then, with the excellent monitoring
we knew before it was a real problem and had no unexpected downtime
surprises. The Eaton/Powerware unit has also been good, but its
monitoring is not as comprehensive. We do rely on regular service visits
to really understand the current condition of the unit. This is covered
under a maintenance contract.

We've found with the small 1400/1500 units, they need to be replaced
with fair regularity. They are good for one, maybe 2 battery
replacements, so maybe 3-4 years total. After that they simply don't
work reliably. I view the PDU's as a headache and manually distributing
load is often just 'best guess.' Don't get me wrong, the small units
are cheap and get the job done, but if I had the budget and the space
I've have inline ups where ever I have more than one rack of equipment.

Re: Battery Power Solutions

Now that even cars run on Lithium batteries, IMHO IT should start using
Diesel engines. Just because we can.

Re: Battery Power Solutions

My daughter came back from Italy and Greece just enamored with Smart cars. She just LOVES seeing them on the road. I think I've seen 3 in all of southern Wisconsin so far. They're great for commuting....not so great for a family.

They don't make that much sense in the US, except for the mpg thing. I
love my Smart for nit using more parking space than a sixpack 🙂
