I Got The Power!

Something that is often easy to overlook when putting new toys in your datacenter is power, UPS protected power in particular.  In the case of most large datacenters this is usually done with a large central UPS systems that power the entire datacenter.  In smaller datacenters or data closets a much smaller rack mount or floor mount UPS is usually sufficient to power a rack or two of equipment.  We are partnered with and recommend APC by Schneider Electric in most cases due to their quality and reliability.

Ok so you know you need a UPS but which one, there are lots of differents models with all kind of ratings like “VA” and “kVA” and all kind of plug options and other configuration.  If you’re like most IT pro’s you probably understand this a little but are far from an electrical engineer.  Fortunately there is a handy tool from APC that can simplify things.  The APC UPS Selector tool allows you to add all kind of devices from established product list and then spits out a power report and recommends products for your specific application.  The tool can be found here:  http://www.apcc.com/tools/ups_selector/

Once your connected everything is pretty straight forward, you can configure your system “by Devices” or “by Load” (if you know it).  The main page looks like this:

If you select “Configure by Devices” you will get a relatively user friendly page like this:

configbydevice

 

 

 

 

 

 

 

 

 

From here you can pick and choose the devices in any combination that you may have in your rack (switches, storage, servers…..) and generate a load report.

If you prefer the more techy “configure by load” approach you can simply enter in the known load of your equipment and your good to go.

configbyload

 

 

 

 

 

 

 

 

As you work through the different pages there are lots of options like allowing for a specific growth percentage and desired run-times at load.  Either way you do it the tool can be a valuable tool if you are trying to figure out how much UPS to buy for a given amount of equipment or for a given run-time at a specific load.  Check it out.
