I rewired my low voltage during home during a renovation 1.5 years ago.

Just got a couple of these units finally.
My unit has 2 IOM6's with 4 PSUs

I think its worth mentioning...
Just deal with 4k sectors now. Build your ZFS pool to support them now
If in a year or two a drive needs to be replaced and no 512 sector drives are available your performance using a 4k sector drive will be terrible.
Its better to create a 4k pool now...
If it helps anyone I've tested the M1015 (lsi 9240-8i) in a s775 Gigabyte P35 and a socket939 nf4-sli based motherboards and it will not work in either
(Testing included testing 1x and 4x slots modified to accept the 8x card, using 16x pcie for the HBA and old pci gfx card, and the SLI...
