OpenBSD Clashes with Adaptec In Quest for Docs

TrumpetPower! writes "OpenBSD developers have been asking for documentation from Adaptec for over four months. Adaptec's response has been to deliberately misunderstand what is being asked of them. A former Adaptec employee admits that the hardware is buggy and tricky to get right. So, as a result, OpenBSD 3.7 will ship without Adaptec RAID support. Personally, I'm glad that Theo isn't resting on his laurels."

    Just a note; the "former Adaptec employee" is Scott Long of the FreeBSD project.

    I have not been using OpenBSD sice 1999, but hardware support was never its strong point... though what it supported was,like all the BSD's, supported extremely well.

    It's a good call, in spirit of BSD. Scott's drivers are exellent and they just need to port those.

      You misunderstand. OpenBSD already have a driver. They want documentation to improve that and more importantly implement a management program which can do critical stuff like check if any drives have failed.

      The management utility in the FreeBSD ports tree is binary-only. OpenBSD refuse to accept binary only crap, which is why they want this documentation.

    Yes, FreeBSD is the most popular BSD. But each BSD is it's own operating system, not a previous version of the same operating system like your analogy.

    It did not start with BSD4.4-lite, go to 386BSD, move to NetBSD, then OpenBSD, then DragonFlyBSD and then FreeBSD. Each are their own system which split at one time or another from the same tree.

    All four of those systems are maintained today and therefore it is not like Windows 9x complaining about hardware support. Windows does not maintain new versions of Windows 95.

    OpenBSD is the extremely secure and extremely open of the BSDs and Unix-likes. OpenBSD refuses to have anything that isn't as Free and Open as their goals describe into their system. Linux and FreeBSD are more into the functionality over ideals idea. NetBSD I cannot speak for though as I don't really follow them.

  3. reminds me of Promise by SuperBanana · · Score: 4, Informative

    Reminds me of Promise's definition of "Linux support" for a card I bought.

    In the case of the SX-150 SATA raid card (which has a hardware XOR engine and whatnot), that meant "we have binary drivers for distributions which are several years old".

    There is some source. Well, it's a 'wrapped' binary driver, and it's only available from "some guy" in Germany who begged Promise support long enough they gave it to him. You a)cannot compile it into the kernel b)cannot compile it for 2.6 because it simply isn't compatible. I sent numerous emails to Promise asking when a 2.6 driver would be available or if there was any updated source code. None were ever answered.

    Same story with the tools- unless you're running Redhat 9.0 or some ancient version of Suse, forget ANY on-line monitoring.

    Not that the customers are much better- one page I found about the card suggested that "software raid is faster anyway", which is an absurd proposition by itself. Regardless, why would you spend $100-200 more on a hardware-raid card complete with cache memory, and then just use the 2.6 SATA driver which only drives the SATA interfaces?

    From what I understand, 3ware has better support for Linux, but that means I have to migrate a large amount of data off the old array..

      Software RAID *is* very often faster, especially on a modern CPU paired with an older design -- you don't buy HW RAID because it is faster, you buy it for battery backup and offloading of low level operations to conserve CPU time and bus/memory bandwidth for user applications and so that if your OS or CPU/memory/whatever blows up, or you lose power, it won't corrupt the data on your disk array. Hardware RAID dedicated processors are simple, slow, "reliable" units -- not ultra-fast bleeding-edge dedicated units like you see on video cards.

    What customers exactly? If you were Adaptec, would you write drivers for your hardware in Windows, a platform you're programmers are very experienced with and caters to the 90% marketshare, or write drivers for the niche 5% MacOS X or 5% other *nix market?
    A re-read of the article might be in order, along with a scan of the other responses. I haven't yet run into a post demanding that Adaptec develop and release open-source OpenBSD (or Linux, or MacOS, or whatever you please) drivers for its hardware -- that's not what we're talking about at all.

    If we accept the claims made in the article, Adaptec won't even release the technical information necessary for people to write their own. That's what the argument is about.

    Everyone on here expects companies to spend millions in development and bend over backwards for their own purposes. We have to be realistic here and realize that we have to make it worth it for companies like Adaptec to support Linux or in this case, OpenBSD. Adaptec isn't interested in OpenBSD because it's not in their best financial interest, despite their best intentions.

    Actually, nobody seems to expect that. Unquestionably a fair number of people would be happy if it happened, but nobody expects it. What people do expect is for Adaptec to release comprehensive technical specifications for their cards to interested parties, a practice that used to be commonplace among hardware makers but has been in lamentable decline for some time now. Releasing the tech specs would benefit not only OpenBSD developers but Linux, FreeBSD, MacOS, and others, and while your assertion is correct that Windows has a >90% market share on the desktop, it's somewhat of a non-sequitur considering we're talking about drivers for a RAID controller that's more likely to go into a server machine. Windows still dominates in that market, as well, but not to the extent that it does on the desktop. By releasing the necessary specs and letting the open source community write drivers that work with their hardware Adaptec could, at very little cost to themselves, expand their potential customer base by 10-20%. Why won't they?

    "Its their decision and people shouldn't begin to whine when they don't get their way."

    And how else do you propose to effect change? Shut and sit down isn't going to work is it?

    Whining, boycotting, shaming, humiliating, mocking, deriding, bitching and moaning is a perfectly appropriate response to an idiot company acting in stupid ways.

    More people need to get uppity. Sitting quietly at your desk doing exactly what you are told isn't going to get you anywhere.
