I personally am using an LSI SAS2008-based HBA with two HP MSA60
enclosures; I then run standard mdraid on top of that:
md2 : active raid6 sdl1 sdw1 sdv1 sdu1 sdt1 sds1 sdr1 sdq1 sdp1 sdo1 sdn1 sdm1
29301335040 blocks super 1.2 level 6, 512k chunk, algorithm 2 [12/12] [UUUUUUUUUUUU]
md0 : active raid6 sda1 sdk1 sdj1 sdi1 sdh1 sdg1 sdf1 sde1 sdd1 sdc1 sdb1
26371201536 blocks super 1.2 level 6, 512k chunk, algorithm 2 [11/11] [UUUUUUUUUUU]
Individual drives are all SATA.
If you have smaller numbers of drives, then a standard SATA HBA is
probably good enough.
Obviously, this set up is not that quick.

Show me your flowcharts and conceal your tables, and I shall continue
to be mystified. Show me your tables, and I won't usually need your
flowcharts; they'll be obvious.
