Installation of the DSSRV2-RAID controller.

Resolution

This article covers the field installation and configuration of the DSSRV2-RAID card.

 

Requirements and notes:

  • RAID = Redundant Array of Independent Disks. Definition
  • RAID5 requires a minimum of 3 storage drives installed. 
  • RAID5 configurations consume the equivalent of 1 drives storage space for parity information, this means if you have 3 2TB drives installed, the usable storage space would be roughly 4TB's (actually less with overhead).
  • DSSRV2's can be purchased with RAID5 pre-configured from the factory or the DSSRV2-RAID card for field installations.
  • The RAID controller does not support UEFI booting.
  • The factory USB Recovery must be run after the card is installed to properly configure.


 

 

Install the LSI 3Ware 9750 RAID Controller into the DSSRV2 chassis

 

  1. Make sure the unit is turned off, unplugged, and the chassis cover is open.
     
  2. With the chassis open, remove the SATA cable ties from the inside left of the unit.
     
  3. Carefully disconnect the SATA cables from the motherboard.



     
  4. Remove the drive carriers from the front of the unit.
    1. Open each drive carrier's latch by pulling the latch to the left
    2. Slide the drive carriers gently out of their bays.



       
  5. Remove the top two screws on the backplanes.



     
  6. Lift the backplanes, and disconnect the SATA cables from each backplane.  Do not disconnect the power cables.  Remove the SATA cables from the chassis.



     
  7. Connect the multilane SATA cables to the appropriate connectors on the backplanes.

    Note: Two sets of multilane SATA cables are supplied.  The first set is numbered P1 to P4. The second set is numbered P5 to P6. DSSRV2's with an optional DVD optical drive installed, the second multilane set would not be used because drive slots 5 and 6 are taken by the DVD drive. The DVD drive stays connected directly to the motherboard on SATA 5. Each cable has a different length, and the connectors are right-angle connectors for nesting. The multilane SATA cables lengths are as follows.

    P1: 317.5 mm (12.5 inches)
    P2: 330.0 mm (13.0 inches)
    P3: 444.5 mm (17.5 inches)
    P4: 457.0 mm (18.0 inches)
    P5: 571.5 mm (22.5 inches)
    P6: 585.0 mm (23.0 inches)

    Non DVD modes will connect the second multilane cable set P5 and P6 to drive slots HD5 and HD6

    Multilane SATA Cable Connections



     
  8. Align each backplane with the two guide pins located at the bottom of the backplane slot. Ensure that all cables are cleared before seating the backplane.
     
  9. Insert and tighten the two screws on the top of each backplane.
     
  10. Unscrew and remove the metal filler bracket for the PCIe x 16 slot.



     
  11. Replace the RAID card’s high-profile bracket with the supplied low-profile bracket.
     
  12. Align the card with the PCIe x 16 slot #1 (first blue slot). Gently press down on the card so that it is properly seated in the PCIe x 16 slot. Insert and tighten the metal bracket screw to secure the card.



     
  13. Run the multilane SATA cables through the slot on the inside left of the unit.



     
  14. Connect the multilane SATA cable plugs to the 4-lane connectors on the RAID card.

    NOTE: The bottom DS-SRV-RAID connector (SAS_1) must be used for the first set of drives (HD1 to HD4 - first set Multilane cable P1 - P4). The top DS-SRV-RAID
    connector (SAS_0) must be used for the second set of hard drives (HD5 and HD6 - second set Multilane cable P5, P6). Only one plug is required for the DSSRV2-DVD.




     
  15. Secure the power and multilane SATA cables by bundling them with cable ties.
     
  16. Close the chassis and insert the drive carriers to complete the installation process.
     

 

The RAID controller is now installed, to complete the installation you must now run a factory recovery to create the RAID5 array.

  1. Run a factory recovery using the provided USB flash drive, follow this KB article for the DSSRV2 procedure: How to perform a recovery on the DSSRV and DSSRV2 series Network Video Recorder   

    On Step 6 of the recovery article, refer to "RAID DSSRV2 configuration option screen" and select the following option:  Convert ALL Disks To RAID5.
