Re: Porting driver from Linux
please let us know your results in testing esxi 4 with 3132.
I have a 3132 card and a 4 bay mediasonic probox. I used the compiled driver (2.6.19) from another thread with ESXi 4.1, and I can say that it doesn't work. Only the first drive is recognized. The same hardware works fine with Ubuntu and FreeNAS, so I can rule out a h/w problem.
I'm not exactly a linux kernel hacker, but I am tempted to try to compile an updated version of the sata_sil24 driver. I haven't looked yet, but perhaps ESXi 5.0 might work more easily with a newer version of the driver.
On the other hand, upgrading to a VT-d capable CPU or just going to a non-virtualized linux server is looking like a pretty good option right now.
