    2120
    2221  * LSI MegaRAID: This is the old high-end cards from LSI.[[BR]]
    2322    It is fully hardware RAIDs controllers supporting RAID5, at least, with various SCSI interfaces.[[BR]]

    3229
    3330  * LSI MegaRAID SAS (megasr crap): This is the first of the broken cards by LSI. I hope you don't have one.[[BR]]
    34     In fact this card has FusionMPT hardware plus MegaRAID BIOS. RAID5 is supported through a proprietary kernel module.

    3632    Both FusionMPT and this fake MegaRAID looks like this in lspci:[[BR]]
    37     ''0d:05.0 SCSI storage controller: LSI Logic / Symbios Logic SAS1068 PCI-X Fusion-MPT SAS (rev 01)''
    38    
     33    ''0d:05.0 SCSI storage controller: LSI Logic / Symbios Logic SAS1068 PCI-X Fusion-MPT SAS (rev 01)''[[BR]][[BR]]
    3934    But if you run lspci -nn you will notice this:[[BR]]
    4035    Real FusionMPT: ''02:08.0 SCSI storage controller [0100]: LSI Logic / Symbios Logic SAS1068 PCI-X Fusion-MPT SAS ![1000:0054] (rev 01)''[[BR]]
    4136    Fake MegaRAID : ''0d:05.0 SCSI storage controller [0100]: LSI Logic / Symbios Logic SAS1068 PCI-X Fusion-MPT SAS ![1000:0055] (rev 01)''[[BR]]
    42     1000:0054 is okay, 1000:0055 is a fake MegaRAID card.

    4438    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.
