    99The FusionMPT SAS2 is a low-end card from LSI. It replaces the Fusion MPT cards.
    10 [[BR]]It only supports RAID0 and RAID1 an can usually be found in many 1U rackmount servers which have only two disks drives. However, I must admit I'm not sure yet there's no RAID5 adapter with thoses chips.

    1111[[BR]]Even it's not full of features theses card appear to work fine and are supported by an '''opensource Linux driver'''.
    1212[[BR]]A proprietary monitoring tool is available but it nearly offers '''no management features'''.

    2020There are many more mpt* drivers in Linux kernel.
    21 [[BR]]Somes seems to be required dependencies. Others looks like being real driver but we haven't used them yet.

    3232There's no opensource tool for theses new cards.
    33 [[BR]]However, LSI provide a '''command line management tool''' named sas2ircu. Management features are really '''basic''', so it's better to use is as a '''reporting tool''' only.

    106 sas2ircu-status is a package I wrote by myself. It includes a python wrapper around tw_cli command and an initscript which daemonize the launch of the wrapper.[[BR]]

    107107It also handles failure detection and report it by mail and syslog. It also handle unexpected output changes and reminders until the status is fine again.
