SuperW2 Posted March 29, 2011 Share Posted March 29, 2011 Is something like the APC BX1300G, 780 Watts / 1300 VA,Input 120V / Output 120V, Interface Port USB work for a 15-20 Drive (non LP, all 7200 RPM drives with lots of fans) system... I have 20 drives powered up right now, with 16 on my Array and the other 4 once I decide I need another SATA Card) I really only want a few minutes to try to force a graceful shutdown in the event of a power blink/outage. I've dropped power 4 or 5 times the last 2 weeks and running Parity Sync/Checks that often is getting kind of old. http://www.apc.com/products/resource/include/techspec_index.cfm?base_sku=BX1300G I really don't want to spend $150 (or wait for another $100 deal), but if I need one this big to provide the couple minutes I need to try to get UnRaid to Auto Shut down. I used one of the Power Supply Estimators and with the drives and fan It recommended something 650-680 watts (for a PS) and I'm running an OCZ 700. I have a Kill-A-Watt meter on it have yet to see it go over 400 Watts at boot up or really any time. Any help or guidance is greatly appreciated. Wade Link to comment
dgaschk Posted March 29, 2011 Share Posted March 29, 2011 A APC Smart-Ups 750 for $100 would likely work for enough time to shutdown. You could always test it and the return it for an upgrade if it doesn't work. Link to comment

mbryanr Posted March 29, 2011 Share Posted March 29, 2011 Believe it was supposed to be a Back-UPS 750 Link to comment
defected07 Posted March 29, 2011 Share Posted March 29, 2011 Does unRAID work with these devices auto-shutdown over USB functionality? Link to comment
SuperW2 Posted March 29, 2011 Author Share Posted March 29, 2011 Does unRAID work with these devices auto-shutdown over USB functionality? I guess I have the same question about the BX1300G if that's the unit I end up with. Link to comment
S80_UK Posted March 29, 2011 Share Posted March 29, 2011 Does unRAID work with these devices auto-shutdown over USB functionality? Yes. I have one of the Back-UPS 800 units ( http://www.apc.com/products/resource/include/techspec_index.cfm?base_sku=BR800I ) connected via USB. It works just fine. unRAID logs short term power failures, but anything longer than the period I have set in apcupsd, the UPS support plug-in, (5 minutes in my case) and then unRAID shuts down. The cool bit is that the plug-in tells the UPS to shut down after a further delay, so that the server has power right to the end and beyond before the UPS switches off cleanly. As soon as power comes back, unRAID is back up in less than a minute. Link to comment
SuperW2 Posted March 30, 2011 Author Share Posted March 30, 2011 I have a co-worker that has a APC Smart Ups 750 that I'm going to try. The Battery needed replacing, but $85 for a new battery is better than $150 for a new UPS. If it's not powerful enough for my UnRaid, I can use on my Main Desktop. Link to comment
SuperW2 Posted April 4, 2011 Author Share Posted April 4, 2011 Used Smart Ups 750 with new battery up and charging now... installed the APC and Clean Power Down Packages from Unmenu and it appears to be working (at least I can see it System Info->UPS Status). I didn't change any of the default settings, so not sure if it will shutdown my UnRaid Server after a 5+ minute power outage, but I hope so. I'll let the battery fully charge and then can do some "unplug" testing. With all my drives spun up, it was listing (again this is while the battery is charging and only at 40ish% charged per the BCHARGE) Spun Up = LOADPCT : 43.5 Percent Load Capacity Spun Down = LOADPCT : 24.7 Percent Load Capacity Wade Link to comment
mbryanr Posted April 4, 2011 Share Posted April 4, 2011 You will need to see what the %Load is while initially spinning up all drives. http://lime-technology.com/forum/index.php?topic=9277.msg88474#msg88474 Link to comment
christuf Posted April 4, 2011 Share Posted April 4, 2011 Be careful unplugging. I've heard of issues doing that, as some UPS's work on the basis a ground connection is present (i.e. even though the power is off, the top plug pin is still connected to earth). I understand the desire to test, and not sure how much of this is speculation vs. fact, but just wanted to highlight to you before you pull any plugs. Perhaps safer to go throw the circuit-breaker wired to that outlet - would be a very real simulation of a power failure! Link to comment

My Kill-A-Watt was in the 375W Range during bootup Link to comment
S80_UK Posted April 4, 2011 Share Posted April 4, 2011 Mine doesn't give the peak figure. This is what I can get... UPS Status (from /sbin/apcaccess status) APC : 001,044,1087 DATE : Mon Apr 04 20:48:57 UTC 2011 HOSTNAME : Tower RELEASE : 3.14.3 VERSION : 3.14.3 (20 January 2008) slackware UPSNAME : Tower CABLE : Custom Cable Smart MODEL : Back-UPS BR 800 UPSMODE : Stand Alone STARTTIME: Sat Mar 26 23:48:13 UTC 2011 STATUS : ONLINE LINEV : 244.0 Volts LOADPCT : 8.0 Percent Load Capacity BCHARGE : 100.0 Percent TIMELEFT : 68.9 Minutes MBATTCHG : 10 Percent MINTIMEL : 5 Minutes MAXTIME : 300 Seconds OUTPUTV : 230.0 Volts SENSE : High DWAKE : 000 Seconds DSHUTD : 000 Seconds LOTRANS : 194.0 Volts HITRANS : 264.0 Volts RETPCT : 000.0 Percent ITEMP : 29.2 C Internal ALARMDEL : Always BATTV : 26.9 Volts LINEFREQ : 50.0 Hz LASTXFER : No transfers since turnon NUMXFERS : 0 TONBATT : 0 seconds CUMONBATT: 0 seconds XOFFBATT : N/A SELFTEST : NO STATFLAG : 0x07000008 Status Flag SERIALNO : 3B0951X24834 BATTDATE : 2001-09-25 NOMOUTV : 230 Volts NOMINV : 230 Volts NOMBATTV : 24.0 Volts NOMPOWER : 540 Watts FIRMWARE : 9.o5 .I USB FW:o5 APCMODEL : Back-UPS BR 800 END APC : Mon Apr 04 20:49:21 UTC 2011 So I can spin up all the drives and get a figure, but it's not the peak start up power.
