July 3, 201016 yr I have a Norco 4220 case and a 650 watt power supply. My questions is if the case was filled with hard drives, it's not yet, what size ups should I get?
July 4, 201016 yr There are user addons that will shut it down for you. I assume this is what you refer to. Manual shutdown requires much much longer assuming you actually leave your home sometimes
July 4, 201016 yr Author Yes, I want it to shut down automatically if the power goes out for more than 5 minutes. What size UPS should I get? Why does it take longer to shut down manualy?
July 4, 201016 yr Yes, I want it to shut down automatically if the power goes out for more than 5 minutes. What size UPS should I get? Why does it take longer to shut down manualy? Get an APC brand, they are easiest to configure using the package manager built into unMENU. Get one with the run-time around where you specified. It takes several minutes to shut down the server, and you don't want it shutting down in a short outage, so powering down after 5 minuets actually takes at least the capability to run 7 or 8 minutes. I have a APC Back-UPS 750 on my server. It gives me about 7 minutes run time. I have 16 disks in my server, most of them 4 or more years old (non-green drives) I have the apcupsd software configured to shut down when there is 5 minutes run time remaining, or less than 10% battery capacity remaining, or if an outage exceeds 300 seconds. The first of these that is reached initiates the shut-down process. With all my disks sleeping I'm at 38% of capacity. All disks spinning, it looks like this: LOADPCT : 58.0 Percent Load Capacity TIMELEFT : 6.5 Minutes My Back-UPS 750 is actually able to provide about 450 Watts of power. I do have the router plugged into the UPS as well, so I can still get to the server in an outage. I know people have used the smaller Back-UPS 500, but on smaller arrays, with fewer disks. Regardless of the UPS you get, the batteries only last about 3 or 4 years, so you'll need to replace them on occasion, and they lose capacity over time, so, 15 minutes run-time when new might be 10 minutes run-time in 4 years. I can see my battery is due for replacement... So, you need a UPS with sufficient Wattage/Volt-Amperage capacity to power your server, and enough battery capacity to power it for the time duration needed for a clean shutdown. Oh yes, it takes longer to shut down the server manually since you might not notice the power outage until you wake the next morning, or when you return home and find power has been lost. Joe L.
July 4, 201016 yr Author thanks but how many watts should I be looking at, more than 650 since that's what my PSU is, or just go by run time?
July 4, 201016 yr thanks but how many watts should I be looking at, more than 650 since that's what my PSU is, or just go by run time? From my post: So, you need a UPS with sufficient Wattage/Volt-Amperage capacity to power your server, and enough battery capacity to power it for the time duration needed for a clean shutdown. How many disks do you anticipate? It does not matter what your power supply is rated for, as you do not draw 650 watts from the wall outlet. Odds are you draw much less. You probably need something similar in size to mine, something between 750 VA and 1000 VA are typical for larger home UPS. Commercial APC UPS have far larger capacity and run-time. I have several of them in my theater, powering the equipment there. (An APC Smart-UPS 1000, and an APC Smart-UPS 1400) They power the projector, the HTPC, the cable box, etc. One of those might work if you need the extended run-time. They can often be found on e-bay at great prices with new batteries installed.. If you wish to know exactly what your server is drawing, consider investing in a kill-a-watt power meter. http://www.killawattplus.com/?gclid=CLLD0-Du0aICFUNf2godLxRRxQJoe L. Joe L.

In my case all drives spun down I get 25% utilization (16.1 minutes) ... and all drives spun up I get 50% utilization (7.8 minutes) ... So depending on how long an automated shutdown takes ... and how many more drives I add ... and what I would assume the battery capacity would be in four years ... this UPS might be going to my HTPC ;-) Once I figure out how to get the apc software to cleanly shutdown cache_dirs and sabnzbd I can start checking the actual shutdown times and then decide if this one can stay where it is Hope this helps a little more too ...
