Solaris 10 x86 device driver for Dell Poweredge 2850

Don't know off top of head on exact model of controller you have, can you be specific? I've got multiple SAS/SATA and SCSI adapters working on Solaris 10 x86, nexenta, and Solaris 11. Some combinations are not supported. Also the "megaraid" is not the same as the "LSI" driver. Different programming interfaces, different product. Dell/PERC vs. non-OEM off-the-shelf LSI so what firmware do you have. Off-the-shelf you can install the LSI MPT-based if target devices are built via the RAID firmware in controller .. but drivers don't exist if you configure controller for JBOD.
