This is at the back of my house, in a sort of extension. It's a bit like a garage but there isn't a hope in hell of fitting a car in it (it's about 6m above road level for one). Edit: Bah. Wrong post. Thought you were asking me but I've got this Friday feeling.

Yes, I do exactly that. The server is in target mode, so it presents itself as an FC disk to initiators. Initiators are 'normal' FC machines; I use mostly QLE2460 cards for those because you can get them cheap on eBay. The software on the server is built-in to Linux kernels 3.5 and above, and...

Mine have been ticking away for the past few months without issue as well. Not seen any errors on them at all, no timeouts from my 3ware RAID controller, and they're really fast compared to what I had in there before (WD Green 2TB).

As your cards are dual-port, maybe you can get some more cables and hook the second port up and add those to the links? I don't actually use IB myself nor know very much about it, but I wouldn't have thought there would be much difference between bonding 4 channels over 1 link and bonding 8...

From my very quick reading of the table at the bottom of http://www.scgs.co.kr/pdf/Qlogic/INFINIBAND9024_datasheet.pdf, it would appear the 9024-CU24-ST2 without -DDR on the end is an SDR switch... :-(

The following link *may* be the guide for your model of iMac. Regardless of whether it's the right one or not, using iFixIt's guides is probably the right thing to do with hardware like the iMac. http://www.ifixit.com/Guide/iMac+Intel+20-Inch+EMC+2133+and+2210+Hard+Drive+Replacement/1008/1

Yes, do it. My 2008 MacBook got a new lease of life with an SSD in it. It is well worth the money.

My brother just bought a few M4 SSDs from Crucial UK directly last week, all arrived with the latest 040H firmware. All the M4s I own running that firmware work very well indeed; I had some issues with all the previous firmware versions though.

One of the advantages that AHCI mode brings over the emulated IDE mode is NCQ (command queuing). That means your controller can send multiple commands to the drive to execute at once, and return the results of them as they become available. With IDE mode, your controller can only send one...

If you already have data on the drive, I wouldn't go for a RAID controller of any sort as they will want to put their own signatures on the drive before they let you use it. HP cards, especially, can be difficult to get working at all in non-HP motherboards, just to add to the pain. You...

The cable might work, but you still need a SAS card to get the drive going at all. Forget about the cable until you actually have a card that will work. SATA cards will not work. I fact no, that cable looks like it would be no use to you for a single drive.

I have only just got myself a SC846BE16-R900B, so very similar to yours but single port SAS. It's a great enclosure and as yours this has a SAS expander backplane which I hook up with a single SFF-8087 to my 3ware 9750-4i. I thought the dual-port ones basically had 2 independent expanders, so...

I may be wrong, but I don't think you can if you're using Windows, as LAG is a driver feature rather than in higher layers. In Linux, doing LAG over NICs from different manufacturers is no problem at all. For other operating systems, I have no idea.

The activity LEDs on my Norco backplanes are run by the drives themselves, and not by out-of-band signalling from the RAID controller. If the drives don't support the feature (I believe it's optional in the SATA spec) to output activity information, the LEDs won't light. It's not necessarily a...
