  • Cracking Open the Drobo B800i

    The Data Robotics Drobo B800i is an 8-bay, iSCSI SAN storage device that's designed for small and medium business environments. It can handle up to eight, 3TB drives for "up to 24TB of raw storage."

    TechRepublic's Mark Kaelin reviewed the Drobo B800i back in June, and I couldn't wait to crack it open.

    For an in-depth analysis of the Drobo B800i's internal hardware, check out my post, "Drobo B800i SAN storage device teardown: Proprietary motherboard with Marvell processor".

  • Cracking Open the Drobo B800i: Sliding off the outer shell

    With the screws removed, you can slide the outer shell off the Drobo B800i.

  • Cracking Open the Drobo B800i: Outer shell removed

    With the outer shell removed, we get our first look inside the Drobo B800i. Unfortunately, there's not much to see yet. We'll need to remove a few more components to view the motherboard and drive interface card.

  • Cracking Open the Drobo B800i: Removing the power supply screws

    First to go is the power supply. Four Phillips screws hold it in place.

  • Cracking Open the Drobo B800i: Removing the power supply

    With its screws removed, you can lift the power supply away from the Drobo B800i's case. Be extremely careful when doing this. Power supply components (specifically the capacitors) can store enough charge to injure and even kill you.

    The Data Robotics Drobo B800i was a snap to crack open. Working on it was like working on a standard desktop or tower computer.

    The unit uses standard Phillips screws, the case is easy to remove, and the internal components are simple to detach.

    Unfortunately, the motherboard and drive controller boards are proprietary--making Data Robotics the only source for replacement parts. Provided you can get the hardware however, most IT pros with previous hardware repair experience should be able to work on the Drobo B800i.
