Works like a charm, straight out of the box!  I also bought a "LSI SAS 9202-16e 16-Port PCI-E 6Gb SAS / SATA Controller" (with four SFF-8644 ports) and four SFF-8644 to SFF-8470 cables). Connected port three on the host controller to port thee (the only one that didn't already have one of these small "condoms" on it [IMAGE]) on the first disk bay and port four on the controller to port three on the second.  Turned on the machine, and all disks was there! But looking at the configuration, I noticed that both bays was on the same controller chip (this controller card have two LSI2008 chips), so I moved the cable on port three to port two.  I've since moved the cables on the controller to port one and three and port 1 (just for symmetry [IMAGE]) on both disk bays.  I haven't yet tried to use TWO cables for each disk bay and I'm not sure what/if I'd gain anything by it. There's not something like 'bonding' for SAS/SATA, so..
I'm planning on buying two used Isilon EX12000 to connect to my Linux server. My question is, considering that there's FOUR SAS ports at the back of the EX12000, how many of these do you need to connect? All four, two or will it work with one? That is, I still need access to all 12 disks!  Usually, with storage racks, you connect one to the host and one to the next storage bay, but how does the EX12000 work in this regard?  I would also like to have any documentation on this expansion bay if it exists.
