1. Card information

MegaRAID SAS is the current high-end RAID controllers series by LSI.
It is fully hardware RAIDs controllers supporting RAID5, at least, with SAS or SATA interfaces.
If you're a looking for information about MegaRAID SCSI connectors, please look at LSIMegaRAID instead.

All theses card can be used with stock Linux kernel which includes a working driver.
It's quite new and thus, may be missing in some not-up-to-date distributions.

There is currently no known opensource tool for this card.
However LSI provide megacli, a proprietary management command line utility which is rather hard to use.
