Interchangeable Data Storage Bricks? 185

No mention is made of what happens when a brick in the middle of the cube needs to be replaced and the whole thing needs to be disassembled. To be really effective, this would need to be teamed up with some sort of a backplane, but the tech is new and neat."

    "No mention is made of what happens when a brick in the middle of the cube needs to be replaced and the whole thing needs to be disassembled."

    Well, except for where it was specifically mentioned in the article.

    The bricks can use cheaper, less reliable components because the failure of a single brick or even several bricks will not shut down or corrupt data in the other bricks, because the data is mirrored in other sections of the array or in backup systems, he said. As a result, defective bricks can stay in place until they are replaced as part of scheduled maintenance, Gardner said.

    • I dont think it would be too difficult to replace a brick during the scheduled maintance. They would probably need to shut down the data for 5 or 6 minutes, remove the defective brick, and it's back up. However this can be done during the end of the day because the other bricks have a mirror.
      Seems like a really great idea.

        Nowadays many data sources must run 24/7 because they serve data worldwide. It really shouldn't be necessary to shut down the data source to replace a disk. RAID on SCSI can already support hotswapping. The only nuance here is to make sure the physical design of the array allows the operator to replace any cube without removing others.

    Caveat: I'm an employee of IBM's Storage Systems/Technology group, but I'm not working on that particular project. I am only discussing things that were in the previous press releases about this product so you won't get anything confidential out of this post.

    The original intent, when this was previewed a year or so ago, was that dead bricks would just stay in there and not require disassembly. See http://www.almaden.ibm.com/StorageSystems/autonomi c_storage/CIB_Hardware/ [ibm.com]
    for some more discussion.

    The concern I have (my role in storage systems is error isolation and recovery) is that when you are running all these individual cubes, each one is trying to isolate what might have happened to its peers (or to itself) and when an error starts to propagate from one cube to the next, which it will invariably do sometime, you could end up with multiple cubes saying "IT'S THAT GUY!" and shooting him (ie, cutting him off) when in fact it was yet ANOTHER cube that started the whole thing by corrupting a message and is innocently sitting there not showing any failures.

    So assuming that situation occurs, you have 1 failed and 1 not-failed cube which need to be fixed, and shutting off the failed one requires removal, which isn't part of the service model for the product. Needless to say, I'm going to be REALLY impressed when they get this working. My peers at IBM are awesome when it comes to storage, so I'm actually not being sarcastic when I say that.

    A more intelligent system may be able to actively monitor the health of each brick, detect a failure, shuffle data around, and plot a path on a screen to the dead brick.
