LSI (http://www.lsi.com/) is probably the most used hardware raid manufacturer.
Many LSI cards are rebranded by OEM. In example, nearly all current Dell servers have LSI cards re-branded as Dell PERC.
Tones of different cards
LSI sells several model of cards which do not use the same drivers nor the same tools.
Here are what we know yet:
- LSI FusionMPT: This is the cheaper card which is usually found in two-drive-bays-only servers.
It only supports RAID0 and RAID1.
See: LSIFusionMPT for informations about this card.
- LSI MegaRAID: This is the old high-end cards from LSI.
It is fully hardware RAIDs controllers supporting RAID5, at least, with various SCSI interfaces.
Deprecated, but still found in many old servers.
See: LSIMegaRAID for informations about this card.
- LSI MegaRAID SAS: This is current high-end series from SCSI.
It use SAS or SATA connectors and can be found in many OEMs servers like Dell's.
See: LSIMegaRAIDSAS for informations about this card.
- LSI MegaRAID SAS (megasr crap): This is the first of the broken cards by LSI. I hope you don't have one.
In fact this card has FusionMPT hardware plus MegaRAID BIOS. RAID5 is supported through a proprietary kernel module.
