= LSI cards = [[Image(logo_lsi.gif)]] [[BR]][[BR]] = Vendor information = LSI (http://www.lsi.com/) is probably the most used hardware raid manufacturer.[[BR]] Many LSI cards are rebranded by OEM. In example, nearly all current Dell servers have LSI cards re-branded as Dell PERC. [[BR]] = 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''': Theses are the cheap cards usually found in two-drive-bays-only servers.[[BR]] It only supports RAID0 and RAID1.[[BR]][[BR]] See: [wiki:LSIFusionMPT] for information about theses cards. * '''LSI FusionMPT SAS2''': This is the new version of the FusionMTP cards.[[BR]] Dell PERCH H200/H700 are based on MPT SAS2 for example.[[BR]][[BR]] See: [wiki:LSIFusionMPTSAS2] for information about theses cards. * '''LSI MegaRAID''': Theses are the old high-end cards from LSI.[[BR]] Thoses are fully hardware RAIDs controllers supporting RAID5, at least, with various SCSI interfaces.[[BR]] Deprecated, but still found in many old servers.[[BR]][[BR]] See: [wiki:LSIMegaRAID] for informations about theses cards. * '''LSI MegaRAID SAS''': This is current high-end serie by LSI.[[BR]] It uses SAS or SATA connectors and can be found in many OEMs servers like Dell's.[[BR]][[BR]] See: [wiki:LSIMegaRAIDSAS] for informations about theses cards. * '''LSI MegaRAID SAS (megasr crap)''': This is the first of the broken cards series by LSI. I hope you don't have one.[[BR]] In fact this card has FusionMPT hardware plus MegaRAID BIOS. RAID5 is supported through a proprietary kernel module.[[BR]][[BR]] Both FusionMPT and this fake MegaRAID looks like this in lspci:[[BR]] ''0d:05.0 SCSI storage controller: LSI Logic / Symbios Logic SAS1068 PCI-X Fusion-MPT SAS (rev 01)''[[BR]][[BR]] But if you run lspci -nn you will notice this:[[BR]] Real FusionMPT: ''02:08.0 SCSI storage controller ![0100]: LSI Logic / Symbios Logic SAS1068 PCI-X Fusion-MPT SAS '''![1000:0054]''' (rev 01)''[[BR]] Fake MegaRAID : ''0d:05.0 SCSI storage controller ![0100]: LSI Logic / Symbios Logic SAS1068 PCI-X Fusion-MPT SAS '''![1000:0055]''' (rev 01)''[[BR]] 1000:0054 is okay, 1000:0055 is a fake MegaRAID card.[[BR]][[BR]] Some users reported a switch available on the motherboard to disable software RAID5 and use the card as a regular FusionMPT card. However I can't find it on a '''Nec 120Rg-1''' so I had to deal with that crap.[[BR]][[BR]] See: [wiki:LSIMegaSR] for informations about this card. * '''LSI MegaIDE''': Another crap by LSI. This controller is fully software.[[BR]] It relies on regular SATA controller (Intel ICH7) and does software RAID using a proprietary kernel module.[[BR]] All what's really hardware on this card is the BIOS that let you define some array.[[BR]] This card doesn't even appear in lspci.[[BR]][[BR]] I found this card in on a '''Nec SI1110R-1'''.[[BR]][[BR]] See: [wiki:LSIMegaIDE] for informations about this card.
