Description:	The LSI SAS3081E-R card provides the greatest available throughput to internal server storage arrays through eight internal 3 Gb/s ports, driving up to 244 SAS and SATA devices. This card offers dynamic SAS functionality including dual-port drive redundancy and SATA compatibility. Utilizing SFF-8087 miniSAS connectors, the low-profile SAS3081E-R is an excellent fit for 1U/2U servers driving up to 4800 MB/s full-duplex. The SAS3081E-R also offers Integrated RAID 0, 1, 1E and 10E for reliable data protection with high-availability. Furthermore, by reducing RAID code overhead, this HBA delivers the greatest internal READ/WRITE performance available, making it perfect for medium to high-capacity internal storage applications.

Kernel (uname -r):	2.6.31-22-server
Distribution:	Ubuntu

Installed two of these on ASUS P6T7 WS motherboard with 16 x WD20EARS SATA drives. While all drives are recognized and usable, modprobe is hung. There is no way tol load any additional drivers and the system is unusable. With single controller card (8 drives) everything works.
Performance is reasonable @ 100 MB/s read (per drive) vs. 110 MB/s read for onboard SATA. Throughput scales linearly with number of drives.
All tests done in pass-through mode (no RAID).
LSI site lists multiple 'current' drivers. The source was not immediately compilable on Ubuntu due to dependency on outdated include files, but was not too difficult to fix. None of the 'latest' drivers resolves 'dual card' problem.
