That would be great. The adapter in the servers is a MegaRAID SAS 8888ELP: http://www.lsi.com/storage_home/products_home/internal_raid/megaraid_sas/megaraid_sas_8888elp/ It is able to drive two sas connectors among 4: 2 internal and 2 externals for a total of 240 disks. > I have no plans to port any of the BIOS fake-raid stuff. Yup, that stuff is worthless and I wouldn't expect to see it in SAS hardware anyway. -- Francois Tigeot
