I think that there are big issues with the 3124 driver. I saw unexplained pauses that lasted from 30 to 80+ Seconds during a tar from a single SATA disk drive that I was migrating data from (using a Syba SD-SATA2-2E2I card). I fully expected the kernel to crash while observing this transfer (it did'nt). It happened periodically - each time a certain amount of data had been transferred (just by observation - not measurement). And this was a UFS filesystem and the drive is a Sun original drive from an Ultra 20 box. I need to do some followup "experiments" as Mike Riley (Sun) has kindly offered to take my results to the people working on this driver. > So, anyone know an inexpensive 4 port SATA card for PCI that'll work > with 10u3 and I don't need to reflash the BIOS on? (I bricked a > Syba...) Honestly, you're much better off with the $125 8-port SuperMicro board that I have been unable to "break" to date. Details: SuperMicro AOC-SAT2-MV8 8-port - uses the Rev C0 (Hercules-2) chip: http://www.supermicro.com/products/accessories/addon/AoC-SAT2-MV8.cfm Kudos to the Sun developers working the Marvell driver! :) In the meantime I hope to find time to test a SAS2041E-R (initially the PCI Express version of this card).
