Skinny Drake will be supported by mfi. Sorry if my earlier info was not clear. Every LSI MegaRaid HBA support whic= h is currently available in "mfi" will not be changed. It will be continue to be supported using "mfi". Thunderbolt (6Gb/s Raid Card) was latest introduction of Raid controller fr= om LSI, which was added in "mfi". Typically plan was to add thunderbolt onw= ards support in "mrsas", but due to business requirements LSI added Thunder= bolt support in "mfi". So here is summary. Mfi driver is freeze in terms of adding new PnP IDs. Mrsas driver starts with "Thunderbolt (Device id 0x005B) and continue to su= pport all upcoming product of MegaRaid family. > Would those only be supported by mfi, or by mrsas and mfi? > Is there already a mrsasutil being planned to replace mfiutil? New management interface will be expose by mrsas as "/dev/mrsasX". If mfiut= il has flexibility to work on "/dev/mrsasX" instead of "/dev/mfiX" we can e= xtend the same utility for mrsas. >=20 > Matt
