I think I would still rather go the Sempron 140 route myself though - I have serious doubts that even a dual core Atom can cope with full bore gigabit transfers, and you can forget transcoding or anything like that on your server also. The power savings aren't their either because of the chipset.

felix - no, an x4 slot won't bottleneck a PERC5-series card anyway. A PERC6 can top 1000MB/s, but the slot won't really be a botteneck in any meaningful way.

Good luck with the build though - I'd be interested to see how it works out. Post some figures when you have them.
Yeah no... Transcoding would never work on an atom board, haha...

And the power savings comes through as a savings relatively anyway, because my current file server is my sig rig performing double duty, and my current HTPC client is the rig in the list below it ("Killah Bawx V"). Having both systems on (and on the same wall circuit, mind you) is a massive energy drain. Being able to save the sig rig for gaming only and having the atom board do all of the serving to the HTPC box will save a lot of power for me, since I can then keep my sig rig off when not gaming.

I'm sure I could have saved more power with a different solution, but I was determined to make an Atom based solution work, so hopefully I can post some good news once I am done with the build.

Has anyone successfully obtained a pair of these cables? https://www2.qualest.co.jp/cgi-bin/i...ASASCBL&page=1

I am trying to mount a 5i into a Chenbro RM31408 case and the top of the ram in the card is almost touching the lid, but I think these cables would work... trouble is... I can't find any of them.

See if you can get a hold of these guys:

http://www.cs-electronics.com/sas-cables.htm

They have the SAS-84RA7P/1m

The only issue I can think of is that one of your cables might not fit due to the cable plugged into the black SAS0 port extending into the area where the white SAS1 connector is... Although, it looks like the cable end is flexible and there is the 4 pin area in between the SAS slots that you might be able to leverage to route the wire away from the secondary connector.

Thanks... yeah, I saw them and sent them an e-mail, but searching their site, I couldn't actually find a stock listing, so hope they carry them still. Then all I have to sort out is getting them to ship Internationally... that could be fun.

Thanks mate

I called them myself and they had them in stock... on the way (expensive, but will hopefully solve the problem of the cables popping out of the card vertically.

On another note, any ideas why I can't get any drives at all to show up on a 5i or 6i card?

Setup is as follows...

Chenbro RM31408 case with the Sata/SAS backplane
Supermicro X7DAL-E board
2 x Xeon 5405's
4 x 4Gb 667 fbDimm

I've tried connecting 5 (new) x drives in various ways, but cannot get any to show up as PD in the Ctrl+R config util.

What I have tried...

1. a single drive attached to one of the breakout cables.
2. a breakout cable connected to the first backplane with drives in place, with and without a drive attached to the other breakout cable.
3. a breakout cable connected to the first backplane with drives in place.

I've had a look at the settings available for the backplane and they only relate to fans and alarms... nothing to do with drive settings, besides which... even with a single drive... it does not show up.

Wrong type of cable maybe? Do they look exactly the same?
The ones I have, are marked K10-1004001-A1177T045 on a sticker on one of the cables.

If you've tried on 2 separate cards I would say the cables are probably to blame. Those numbers don't look familiar to me, and a google search yields nothing relevant.

There are 2 types of cables that look almost identical, but only the one will work in each specific application. For instance, a crossover cable is usually used for fanout expanders or drive trays which require a crossover, while the passthrough cables usually connect to backplanes or bare drives.

Thanks.

I suspected as much.

I desperately hope the $175 I spent on those right-angled ones end up being the right type then, or I'm in deep doodah!

So I definitely want 'passthrough' ? (for connecting to the backplanes)

Is there any way of knowing whether these cables "SAS-84RA7P/1m" on that link you provided, are crossover or passthrough?

As far as I can tell, those are passthrough (straight-through) cables. I am not sure what you require, but I can bet it is most likely a straight-through cable.

$175 is pretty steep! I think you can get a better price, honestly. That costs more than the card itself.

So, I've been a avid fan of Perc cards for quite awhile now and even went so far as to buy a perc 5/i for my server and now a perc 6/i for my main computer.

My perc 5/i has been operating fine, but my perc 6/i is showing some weird behavior. I bought three SAS Seagate 15k.6 HDs and have them running in a raid 0 array.

Originally I tested each one of the HDs individually to make sure they worked (putting them in their own raid 0 array). I had booted off two other hard drives and at the time the card was running as a secondary HD system. At first one of the HDs was doing what sounds like constant read and writes, like the head was going back and forth across the HD constantly. This eventually stopped and I thought it was just doing a background initialization or something.

The other two hard drives never did this and they both tested out fine. I decided to put them into a formal raid 0 array to test performance. This was of course capped at almost completely 240 MB/s because I don't have a BBU and I couldn't turn on WB over WT (the option to override apparently doesn't do anything). It worked fine.

I think tried a raid 5 array just to see if there was any sort of performance drop and there wasn't, still nothing like what the first drive did.

Finally I nuked the array and made a raid 0 array which was my original plan. It worked out fine and I started installing windows 7 on it. After I got installed and into windows I was working on my laptop when all the drives started doing what sounded like read/writes (you could and still can hear the drives constantly moving across the platters).

I thought this was temporary again, but it hasn't stopped for about 10 hours. It stops whenever the disks are accessed, but once again starts up as soon as they're done being accessed. Sometimes it starts in the middle of being accessed, but stops almost immediately. Of course this messes with HD tach and HD tune tests. You can see where there are dips where the drive pauses to do it and then starts back up.

Otherwise the drives operate completely fine and have no bad blocks. I thought originally it might be a patrol-read, but looking into Megaraid storage manager reveals that it isn't doing anything like it. The manager shows no errors or warnings besides that the drives are 'unidentified' and that the BBU is missing so it's dropping out of WB mode into WT.

Anyone have any idea what's happening?
