drealit - Thanks man for that info! I will definitely be getting most of those plugins. I do have a UPS unit sitting on my floor next to the server! I'm in IT and we use APC UPS's only so i found myself a spare one that i just need to pop some batteries in and i'm good to go!!!!

On a side note I've got everything ready to roll minus my sata card!!! Server needs some wire management but that will come after i've got everything up and running. I'm working from home hopefully all day tomorrow so i can anxiously wait for the UPS truck hahaha

Just an update, got everything up,

Its doing a Parity-Sync which is taking forever. Another 400 minutes to go

after that i've got to check parity and i'll be good to go

You shouldn't need to check parity after your initial parity sync... you should be good to go. What speed are you getting if you don't mind me asking (for your parity check)?

I'm using a Mobo that isn't on the hardware compatible list so in order to get it on that list i have to pass through three steps. Step one is to successfully compute parity and check parity + post my syslog on unraid forums

I'm at 34,000 KB/sec

Ah very true and thanks for contributing your experience with that mobo. I'm sure there will be people out there wondering about if they can successfully use it.

Your parity check speeds are a bit on the slow side compared to what I get normally. Then again I do have all Hitachi 2TB drives (5) running except for 1x2TB WD GP(32mb version), 1x 500GB Maxtor (old), and 1x 500GB WD GP. But even with those slower drives my parity checks are up around 55-75MB/s. Once you get that parity check out of the way I would explore some options to squeeze out a bit more bandwidth. There's a few commands you can run to fully test your speeds. I'll look them up and copy/paste them here for you when I get a chance.

Please do, that would be very helpful!

I'm running all WD 2 TB drives (3). Parity check is complete, i was playing around with unmenu and a few other plugins this morning. I'm now transfering all my media over from my old external 1TB WD HDD, Should be done by the AM i couldn't figure out where the esata was bottle-necking since i'm only getting 15MB/sec.... I said to hell with it and started the transfer anyway. Roughly 900GB of Movies which is taking around 15 hours

hdparm -tT /dev/[hs]d?

Here is the command. Just login through telnet/putty and it should do some benchmarking and print a read out in a little bit.

Here's my results also so you can get a comparison (the first MB/sec is somewhat of an anomaly apparently and the 2nd number is what you want to pay attention to):
(Again this is on an Abit AB9 Pro motherboard and I also have 2x PCI-Ex1 Rosewill SATA cards with 1 drive each)

Oh and I finally found the post related to installing screens - http://lime-technology.com/forum/index.php?topic=2817.msg24827#msg24827 .

• cache_dirs (basically indexes your entire system so you don't need to spin up drives if you're just browsing - only during playback).

Excellent!

That was my WD 2TB drive... but you're using them all on a TX4 card which shares a single PCI lane. Considering that factor, your speeds seem very reasonable. All looks to be well enjoy your server!!

The next UnRaid version should contain a newer linux kernel which should boost speeds even more (someone said close to a 25% increase in speeds - real world speeds not just benchmarking). Right now Tom is catching up on server orders so development is on hold... but he'll be back in due time. I surely can't wait!
