Hi all,

I hope to clarify a few things

LSI 2008: SAS2 (6GBit) HBA, can do Integrated Raid, but currently not
supported, Driver: mps (Linux: mpt2sas)
LSI 2108: SAS2 (6GBit) Raidcontroller with Cache, optional battery...
Driver mfi? (Linux: megaraid_sas)
LSI2208: Dual Core Raid Chip?!? I haven't seen this one until today.

The driver claims to support 2[0-2]08.

I hope I have time this week to plug some cards into a FreeBSD-Machine to
let you know what exactly works.

Regards,
 Michael!
