Raid controllers

  • controllers where RAID can be disabled, and all disks are exposed to host are called: HBA, JBOD, IT-MODE
    • H200
    • H310 ???
    • PERC 6 (no i letter)

Dell

  • SAS1 - 3Gbps
    • SAS5E
      • SFF-8470 connector
      • supported by MD3000 (the same SFF-8470 connector)
    • SAS6E
      • SFF-8088 connector
  • PERC 6
    • no memory
    • only JBOD, RAID0, RAID1
    • disks exposed to host
  • PERC 6i
    • memory
    • 3Gbps connector, requires such midplane
    • no possibility to expose disks directly to host (trick is to create one RAID0 per disk)
  • PERC 6iR (PERC 6 I/R)
  • H series - SAS2 - 6Gbps - different connectors comparing to SAS1
  • PERC H700
    • SAS2
    • SSD support
    • battery option
    • memory slot
    • must be inserter into dedicated PCI RAID slot
    • no possibility to expose disks directly to host (trick is to create one RAID0 per disk)
  • H200
    • plain HBA
    • no raid
    • JBOD - all disks exposed to host (so called IT-mode)
  • H310
    • plain HBA
