583160 2007-08-20 10:57:00 Does anyone have any opinions about a centralised UPS vs individual UPS?

There are about 4 PCs and two laptops involved . the 4 PCs are in the same room, some are on the opposite sides of the room .

How practical is it to use a centralised UPS vs an individual UPS for each PC?

The two products suggested by my supplier are . . .

vs

They both seem rather costly, anyone has other products to suggest?

583161 2007-08-21 03:43:00 Our primary server room has one UPS for all the servers (about 20 HP GL330/360 systems). It's a Galaxy something-a-rather which provides about 20mins of power to each of the systems before it cuts out - it'd probably last longer if the Administrators only put the core infrastucture on it and let the others power down -but it's a shared room and we're not allowed to touch anything short of replacing our servers.
The one benefit with this however, is the power runs through the walls straight from the UPS - we don't have to run extension leads or anything to the UPS, we can just plug into the wall sockets and know that they're on the UPS straight away.

The other server room, where we have control, runs 3 servers and an Avaya phone system - we run 1 of the servers (HP DL380) and the switches on something like an APC 1200W UPS and another server plus the phone system on another.

We've had power outages before and these have given us a good 30-45minutes each before they've cut out, however usually we turn off the servers once we realize there's an outage and let the UPS power the phones. With this just powering our phones we usually get an hour and a half out of it with the UPS just under 50% battery power remaining (I can't tell you how long the UPS lasts as no powercut's ever lasted more than an hour and we don't test our UPS systems over 1.5hrs)

At our remote sites, we have a server to do local Active Directory, DNS, WINS, file server, etc - these local servers have an APC 1000W UPS connected to them which we've never had issues with. The UPS powers the router, the switch and the server (ensures connectivity to Head Office in an outage).

At the end of the day it really comes down to what you require from your UPS, how long you plan for it to last in an outage and whether you prefer having one UPS to manage vs one per pc. along with whether you have the ability to get cables from a central UPS out to all the clients or not.

I guess my concerned with the centralised UPS is like what you said . . . "along with whether you have the ability to get cables from a central UPS out to all the clients or not . "

It all depends on whether the client wants to spend $400+ for each PC with individual UPS or $3000+ for one that covers all PCs and routers .

I don't know how routers can plug into this UPS with those sockets, may be they come with some form of cable adapters?

583163 2007-08-21 04:47:00 If you're only going to power PC's, then you'll be able to find Male to Female IEC Extension cables from your local Dick Smith or other electronics store which will do the job rather nicely.

Otherwise you could grab a couple of those 4 way powerboards from Dick Smith and a couple of male IEC adaptors, cut off the mains power plug, wire it up to the IEC plug and bob's your uncle!
If you don't feel comfortable doing this, since you're shelling out on a UPS, you could spend a bit more and get your local sparky to do this for you?

Then again, if you do want to go for a solo UPS, get a sparky in to give you a quote on what it would cost to get power from the UPS out to all the PC's plus another few mains plug for the routers/switches/etc.
They'd be able to tell you the limits of the UPS and will ensure you won't be overloading the UPS or doing anything stupid like that
