  1. Centera on Distributed Storage Systems for Linux? · · Score: 4, Informative

    Get A Centera.

    I'm biased but this is a high level Linux based storage system done right. It's not easy to create a coherent storage system out of lots of separate machines, the software that runs on this cluster does a lot of work. This thing fully redundant with no single point of failure, dynamically expandable without even taking it offline, it scales to 100's of terabytes and manages all that content continuously (scanning for corruption and fixing it, garbage collecting, etc..). The cluster has redundant backend networks and parallel paths everywhere, it even uses reiserfs to store the data. There's a lot of good engineering in this unit and they sell it at a decent price compared to NAS boxes.

    Check it out:

    I do work for EMC (like I said.. I'm biased) but I don't speak for them, my opinions are my own.

    Storage clustering is simply hard to do while still presenting a low level filesystem interface. Tossing that out and creating file storage as a high level service with a richer interface seems like the right approach to me. Show me a storage clustering solution that doesn't do that and I'll show you something full of bugs, expandability issues, limitations, and pain points.

    The really toublesome thing I see here is the simple fact that the doctors don't know what they are talking about! They are making STRONG recommendations and have been for years based on some simple rules that are backed up by little or no real science:
    1. Being fat makes you die faster
    2. Eating fat makes you fat
    3. Eating fat ruins your heart health
    4. Lowering cholesterol will make you live longer

    Medicine is about as much a science as Voodoo! (I think that was from Stargate Atlantis.. not sure)

    The fact is that there is little to no credible science behind these recommendations. It's based on untested theories, speculation, and industry funded semi-science (now we'll hear about a study from a Mazola rep showing that butter is really bad for you and Margerine is much better.) Doctors, news programs, magazines, books are all making huge sweeping recomendations (cut all fat out of your diet, drop those cholesterol levels, get rid of that nasty butter and replace it with new Promise HeartSmart death sticks.) They make these recomendations based on tiny bits of inconclusive evidence and, while they usually include little disclaimer words like "some studies show" and "recent theories suggest" they then procede to hand out recomendations like this stuff is known fact and people follow it as gospel. This is because doctors have the most powerful motivator of all time, "or you will (possibly) die"

    This would all be fine.. unless the recomendations are just plain flat out wrong, and as time goes on it looks like this may be the case way more often than it should be. The truely criminal part showed its face when the low carb diet got popular. Suddenly, there was mountans of evidence that "Eating fat makes you fat" and "Eating fat ruins your heart healt" were flat out BS. According to the popular medical theory of the day this diet should have made you pack on pounds like mad and throw your cholesterol through the roof which would clog your arteries at a record pace. This was obviosuly not the case, and should have propted serious soul searching from doctors everywhere about the flaws in the recomendations they have been making and what was broken in the medical system had caused them to make such serious errors. But what did you see on TV... doctors everywhere warning that you lost weight too fast on it which was bad for your kidnees so everyone should stay away from it! Ignore the fact that completely untested theories had been treated as fact for 30 years. Ignore that it was probably industry sponsored science that was allowed to inject and continually defend the incorrect theories. Pay no attention to Dr Atkins "or you will die."

    The medical profession was established to fix things that were broken, not to keep things from breaking. You cut your head open, we can stitch it back up; Your heart stopped, we can get it going again; Your leg is broken, here's a cast; and the reaserch is all setup along the same lines, here's a problem, figure out how to fix it. Making recomendations for good health is different though. It requires different scientific methods than break/fix does and the medical community isn't setup to work that way.

    The other big issue is that the whole system is setup to favor research which will increase income for doctors and medical companies and to leave unfunded research that would cheeply and easily help patients. If some fruit, say for example blueberries, could be used to lower cholesterol how much money do you think would go into the research of that vs the ammount that went into a copycat drug like Zocor? Is that really the right thing to do?

    If doctors really made us healthy, they'd reduce their business and while I trust that MY doctor genuinely has my best interest in mind, I also trust that his boss doesn't and neither does the boss of the reasearch doctor working for Merck who assigns him to projects.

    I'm guessing people have spent a LOT of money on reliable storage solutions and tend to be irrationally dismissive of the possibility of inexpensive redundant storage.

    The fact is, if you know Linux well, maintaining a Linux based RAID array for home use is perfectly reasonable and generally quite painless. I build an inexpensive 4 drive 480GB RAID array a few years ago that I've been delighted with since. I have survived a disk failure with minimal downtime and no data loss.

    "And when the house burns down?"

    I'm so tired of this stupid argument. Data loss due to fire will happen with or without RAID. The fact is, losing a disk is much more likely than having your house burn down by a very large margin (I'd take a rough guess that disk loss in a 8 disk system is about 10,000 times more likely than disk loss from fire). But even if they happened with the same frequency you'd still be reducing your exposure by 50% by eliminating data loss from disk failure with RAID.

    I have yet to find an online company selling properly configured systems for a reasonable price.

    I thought about building a standalone storage server recently and saved my design in a newegg wishlist

It adapted to SIMD (Single Instruciton, Multiple Data) efficiency issues by adding MMX/MMX2/SSD/SSD2 and 3DNow.

    Only in trivial situations will the implications for the security be obvious.

Most of the rest fall under SEC or military requirements where the security repercussions are obvious to those involved and the option to not have dedicated security personell doesn't really exist.

    Security for cars requires an ongoing assessment of risk and selection of appropriate mechanisms to mitigate that risk.

    "Could benefit from" is not the same as "requires". There are lots of things you could do to better secure your car. Should you?

    Absolutely, and that was intentional. Many people view security professionals as impossible to do without (this view seems to be especially popular among security professionals). That may be true now, but it will be less so in the future. The reason I pull out the big guns of "theoretically impossible" is because humans suck at doing things like security. If the computers can do it for us, someone will figure out a way to make them and odds are it will do a better job for less.

      If there is no way around the security measures then why do they need to know why they are doing them? They are doing them to get their work done.

    • Taking decisions to mitigate risk where tradeoffs must be made between productivity and security.

      What if the options are wildly easy to understand and come pre-implemented. Think: car alarms. Fifteen years ago, someone could convince you to spend a lot of money on auto security and it was a complicated business. Today, while the president's limo has upgraded security most of us live with what comes with our cars because it's good enough.

    • Identifying real-world business practices which can enhance security without negative effects on legitimate interaction.

      Again, you are assuming that this is a complicated thing. Managers don't have security professionals to help them decide who to give keys to the front door of the building. Computer security is a giant mess right now. It won't stay that way.

    The risk in hiring a computer security person is that they will cost more than the problems they solve. As software bugs get worked out and security is more automated and automatic, that risk increases.

    For the same reason you don't see armed guards x-raying everyone going in and out of a Walmart you will see fewer computer security people at companies. At some point, it's cheaper to deal with the issue than hire security people to lessen it.
