I wrote an email to the people mentioned in the iir man page asking for clarity on the supported hardware etc, and didn't get a response... The fact that you are seeing change is a good thing... SOMEONE is doing something to the code - does anyone know who? If I get the new gear, I could set up remote console access so that the appropriate person could work on it... that level of C is well beyond me, but I figure providing access to the gear would help - does anyone know who to communicate with? The new boards SE7520JR2 don't support / aren't certified / recommended with some of the older storage controllers... I could use it with an adaptec - but that seems like a crime when there such neat offerings from Intel with such impressive specs. The new board supports "HOSTRAID" - not sure what that is, but neither is anyone at intel support ;-) I've seen references to adaptec, but the controllers on board are LSI Logic - not adaptec. The compatibility matrix: http://www.intel.com/design/servers/buildingblocks/boardsmatrix.htm Seems to indicate SRCS16, SCRZCRX, and SRCU42X are compatible options... SRCS16 is a SATA raid controller.... SRCU42X seems like it's over the top for my needs... the most expensive one... SRCZCRX seems most appropriate for me. My goal - after discussion and feedback from the list is to run RAID mirror sets of 10K scsi drives... so hardware xor speed isn't important - it's quite a basic setup. If I use the old generation boards, the SCRZCR will be appropriate - but it doesn't work - except on the beta? So the hope of seeing the SCRZCR work is slim eh? So - how do I get to the people who can tell me if it's supported? Or so I can get them the resources to debug? Or should I just stick to a ADAPTEC 2120S or a LSI 3201064KIT MEGARAID U320-1? Thanks again! m/
