Keep in mind, I don't have any way of proving that my problem was the same as being discussed, but the symptoms sound very similar... Furthermore, the fact that when I doubled the ram and reduced the number of drives being simultaneously pre-cleared (and by so doing, reducing the number of log writes), the system stopped crashing, makes me believe that they were the same issue... As far as the demanding-ness of unRaid, I wouldn't worry about 2GB of ram. Before the crashing, 2GB was more then enough for me. I pre-cleared multiple drives before without issue, and haven't seen any measurable performance improvements from the extra ram in everyday use (Other then it stopped the server from crashing while pre-clearing the bad drive). That said, I have left it in, simply because it's there now and I have no other pressing need for it (Well, I did pull it from my gf'S Hackintosh, but it seems happy with just 2GB... )

I have no discernible delay with my Harmony... I push the button, XBMC responds as expected... It's an 880 as opposed to the One, if that makes any difference... One thought is that I never used another remote with XBMC, so perhaps I just have nothing to compare it to... though I'm sure I would have noticed a delay if there was one (that sort of misbehaviour drives me nuts )

This is food for thought! I had a couple of bad EARS drives that failed on pre-clearing and would crash the system. I didn't know what was doing it (I just assumed it was bad drives) at the time, but exploding log file makes sense... Especially since I added 2 more GBs of ram (4GB total) and went down to preclearing one drive at a time, and they still failed the pre-clear, but they completed without crashing...

Hello! I finally got around to hooking up my new APC SC-1000 UPS, and I can't seem to get apcupsd to work with it. It came with 2 cables. One is a serial connection on the UPS side, and a USB connection on the unRaid side, while the other is Serial on both. The old UPS was RJ6 (or something like it) on the UPS side, and USB on the unRaid side. In the unMenu interface, I had "Use serial port" set to "NO", and "Cable Type" set to "Smart". These settings don't seem to work for the new UPS, and I tried pretty much every combination possible. I've been trying with the Serial/USB cable. This is the error I'm getting: Error contacting host localhost port 3551: Connection refused Also, the only thing I haven't tried is rebooting between setting changes. Is that required? Thanks for any advice!

Thanks for that! I always wondered how much difference CPU wattage would make, but never went so far as to actually do the math

Using the i3 540 as a benchmark for pricing and performance ($120 in Canada, and scores a 2847 on cpumark http://www.cpubenchmark.net/high_end_cpus.html), here's a sample: i3 540 Price: $120 Score: 2847 Watts: 73w (but idles very low in unRaid, according to numerous posts) x4 600e Price: $85 Score: 2601 Watts: 45w x3 455 Price: $95 Score: 2828 Watts: 95w x4 630 Price: $90 Score: 3251 Watts: 95w x4 920 Price: $100 Score: 3307 Watts: 125w x4 640 Price: $100 Score: 3756 Watts: 95w Keep in mind wattage varies greatly. The i3 is an efficient processor (especially at idle), so if you want almost the same power efficiency as well as performance, you're limited to the x4 600e. If wattage isn't important, there's a bunch of x3 and x4 processors that are cheaper and more powerful, but use more juice... And this was just a quick sample, there could be other cpus out there that are a better fit .

I just recently upgraded my source drive from an older IDE drive to a slightly less old 7200RPM SATA drive and gained approx. 10 MB/s on transfers... In my own experience, this has been the biggest speed improvement for me. I also upgraded the Cache drive to a slightly faster drive, but saw much less of an improvement. Also, try using a cache drive. It should add more 'perceived' speed to your transfers...

Interesting! So nothing is actually saved to disk anywhere. Good to know! Re: MC: I've actually tried it before and found it did not increase my speeds overly much (on a protected array). Using Teracopy on my pc, transfers tend to run between 20 and 25 MB/s, when going from disk to disk or share to share. When I tried transferring via MC, I was only seeing a few MB/s more. I'm in no rush for the transfers to complete as I usually do it overnight, and the convenience of TeraCopy and queuing outweighs the speed boost .

When transferring data between disk or shares in unRaid through Windows (let's say transferring from disk1 to disk4), my understanding is that the data needs to go from disk1 -> PC -> disk4. I have seen this in action with bandwidthMonitor (Up and Down stream are both saturated), but my question is where is the data going on the PC before it moves on to disk4? Is it being copied to the temp folder on c: first?; held in ram?; passing through a wormhole? Thanks ! DB.

For those not following grandprix's other thread, NewEgg got back to me and informed me that the replacement Jetway board should be in stock in a few weeks...

Yup. From NewEgg. It's the response to my query regarding the new replacement Jetway board (HZ03-GT-V2) that grandprix identified... I tried finding another board in the sub $90 range that has 6 sata, 2 16x PCI-e, and onboard video, and couldn't find anything, so if this board is at least under that, we're ahead of the game...

Success! Hello, Thank you for your inquiry. According to our purchaser, we should be carrying the motherboard you have requested within about 2-3 weeks. As that timeframe approaches, please check our website for availability.

The board looks great on paper! 2 pciE 16X, 6 SATA Ports. No video, but a cheap PCI video card could take care of that...

done! Let's hope they bring this board back!

Excellent question! I recently made the switch from desktop- to server-running apps to reduce the number of machines on 24/7, and I just assumed risk would be the same, as anyone who gets into my PC can just as easily access my server through mapped drives... I'd love to hear some responses from the gurus on this board!

That's a pretty cool running drive! What do your SATA drives run at while the IDE is at those temps? Is this a normal quality of IDE drives? DB.

So I just finished pre-clearing the Hitachi drive, and ran a disk speed test from unMenu, and am pretty impressed with the performance. Here's the output: /dev/sda: Timing cached reads: 3438 MB in 2.00 seconds = 1719.65 MB/sec Timing buffered disk reads: 86 MB in 3.03 seconds = 28.37 MB/sec /dev/sdb: Timing cached reads: 3268 MB in 2.00 seconds = 1634.52 MB/sec Timing buffered disk reads: 84 MB in 3.01 seconds = 27.87 MB/sec /dev/sdc: Timing cached reads: 3252 MB in 2.00 seconds = 1626.43 MB/sec Timing buffered disk reads: 304 MB in 3.02 seconds = 100.77 MB/sec /dev/sdd: Timing cached reads: 3340 MB in 2.00 seconds = 1670.37 MB/sec Timing buffered disk reads: 312 MB in 3.00 seconds = 103.95 MB/sec /dev/sde: Timing cached reads: 3514 MB in 2.00 seconds = 1756.97 MB/sec Timing buffered disk reads: 286 MB in 3.02 seconds = 94.76 MB/sec /dev/sdf: Timing cached reads: 3314 MB in 2.00 seconds = 1657.43 MB/sec Timing buffered disk reads: 298 MB in 3.01 seconds = 99.16 MB/sec /dev/sdg: Timing cached reads: 3286 MB in 2.00 seconds = 1642.85 MB/sec Timing buffered disk reads: 318 MB in 3.01 seconds = 105.71 MB/sec /dev/sdh: Timing cached reads: 3312 MB in 2.00 seconds = 1656.41 MB/sec Timing buffered disk reads: 300 MB in 3.02 seconds = 99.36 MB/sec /dev/sdi: Timing cached reads: 3332 MB in 2.00 seconds = 1666.22 MB/sec Timing buffered disk reads: 322 MB in 3.00 seconds = 107.29 MB/sec /dev/sdj: Timing cached reads: 3334 MB in 2.00 seconds = 1667.11 MB/sec Timing buffered disk reads: 306 MB in 3.02 seconds = 101.44 MB/sec /dev/sdk: Timing cached reads: 3328 MB in 2.00 seconds = 1664.26 MB/sec Timing buffered disk reads: 276 MB in 3.00 seconds = 91.95 MB/sec /dev/sdl: Timing cached reads: 3280 MB in 2.00 seconds = 1640.15 MB/sec Timing buffered disk reads: 412 MB in 3.01 seconds = 136.84 MB/sec /dev/sdm: Timing cached reads: 3318 MB in 2.00 seconds = 1659.37 MB/sec Timing buffered disk reads: 296 MB in 3.02 seconds = 98.10 MB/sec sdl is the new Hitachi drive. The rest are WD Green EADS and EARS drives, as well as a couple of older Seagate 7200RPM drives. Once my cache drive finishes transferring all the custom folder data over, I'm going to try the Hitachi as Cache drive and see if performance is affected...

I have the non-modular model (TX750), and it has been great (currently on 12 drives). Also, you can save a few bucks if modular isn't absolutely necessary. Here's a CDN vendor that has it on sale for CDN$90: http://www.ncix.com/products/?sku=26415&affiliateid=7120027 Here's the US version (same price): http://www.ncixus.com/products/?sku=26415&vpn=CMPSU-750TX&manufacture=Corsair&promoid=1302 At 2amps a pop, 20 green drives is still only 66% capacity, amp-wise (still leaving room for other bits using 12v)... [edit] Just saw the "£" sign, so my links may be of no use . If the 850 is only a bit more, then might be worth it....

Has anyone else noticed that when you change the path for the data files for finished downloads in Transmission Remote GUI, Transmission crashes and usually needs a complete server reboot to bring back up? It doesn't seem to happen with smaller files, just multi-GB ones...

Nope. The system drive is a small SSD drive. The one that unRaid is reading from is purely for data. I'm very curious to see what happens now if I put a faster cache drive in place. Currently using a WD EARS drive, but will have a new Hitachi 5K3000 cleared shortly. They seem to have slightly higher speeds then the EARS, so if it is the new bottleneck (The cache drive instead of the old IDE source drive), perhaps I'll see another slight jump in speeds... DB

THANK YOU Kizer! I can't believe I've been building computers for 20 years, and never came across that simple mod!!! Just put together my norco 4224, and couldn't believe how loud those 80mm fans were! (especially the two at the back). I swapped the 2 leads, as per the link above, and voila! All 6 fans are running at 7 volts, and I can no longer hear the server running from 2 floors up! I was originally planning on getting the 120mm fan wall from Norco and replacing all the fans with quieter ones! I think with the fans running at 7volts, nothing needs to be replaced! If anyone thinks this is a bad idea, please don't hesitate to let me know! I'll keep an eye an temps, as I imagine things will heat up a bit more, but hopefully everything will stay in the high 20s, low 30s...

Hi folks, Thought I'd post a little tidbit I learned today: I've always had transfer speeds hovering around 30-40MB/s between my PC and my unRaid server's cache drive. Though not terrible, I keep seeing people talk about average speeds in the 60s/70/80 MB/s, so of course, I had to wonder what was wrong with my setup... I've always suspected that the source drive in my system may have been part of the problem, and sure enough, when I replaced the OLD 5400RPM (I think) IDE drive out of my PC with a slightly newer 7200 RPM SATA drive, I gained about 10 MB/s in transfer rate... I've gone from an average of 30-40 MB/s to 40-50 MB/s. Still not bleeding edge, but a pretty solid increase. So, for anyone suffering slow transfer speeds, this may be a place to look... Cheers, DB . [EDIT] Added 'cache drive' for clarity

So just an update. I ended up ordering 2 of these rail kits (one for my Norco 4224, one for the APC SC1000 UPS). Probably won't get them for a couple of weeks, but I will post back when I receive them, as far as fit etc is concerned. Definitely the best price I could find on recommended quality rail kits. From the [H]ard Forum link above, they seem to be fairly flexible as far as fitting different racks, and people have definitely used them with Norco cases. You can buy the same model through Ebay, but they are more expensive... DB.

That's me! I haven't actually solved my problem yet, as I am waiting on some potentially free rails from a connection who sells servers for a living... If those don't come through, however, the links the kind people of this forum provided me give 2 options for mounting the 4224. The Gruber-type rails from the first link (Thanks jamerson9!), or the standard Norco brackets from the second (Thanks d60pdp!) link. One concern I might have with your specific rack is that the 4224 is 25.5 inches deep, so if your rack is 25 inches, it may be too short... unless the case can stick out the back a bit.... As far as the shape of the holes, I'm sure I came across round instead of square server hardware in my travels. Check out some of the links from [H]ard Forum. There are some good e-tailers listed... HTH!
