Linux vs. NT Reliability

If it's a survivable problem (single-bit error, timing glitch, scsi error, failure of non-system disk, etc), then a crash brought on by it is a software problem and cannot be attributed to hardware. So I find it hard to believe that the nt system had 68 times as many hardware failures. Either, as I said, they were exceedingly lucky, or 68 more crashes should be blamed on enntee, not hardware problems. A crash caused by a nonfatal hardware problem is not a hardware problem at all. It's the responsibility of the os to handle hardware problems as gracefully as possible. This means that other than hard, undetectable memory or processor errors (a three-bit error, a cooling problem, etc), pretty much nothing should cause a system crash. Linux does a decent, but not great, job of recovering from hardware problems. I have no idea how well enntee recovers from them because every time I've used it it's killed itself so quickly it's impossible to tell what caused the problem. Linux will at least dump an oops or panic if at all possible, but enntee seems to just freeze up most of the time.

      Since the primary problem with Linux was the disk subsystem it is concevable that by using a hot swappable RAID drive you could increase its reliablity to the the 99.99% range.

Of course it may be more cost effective to hire more support personnel to fix broken boxes rather than put a hot swapable raid drive in every machine, this would be a business decision.

      Going by the hours of down time per OS, you would need 4 hours of support per year per Linux box. Those same 1000 Linux boxes would need 4000 hours of support a year, or 2 FTE's simply to fix the boxes as they break.

      The RAID drives would drop this to about .67 FTE. I would recomend the raid drives if they cost less than 2 FTE's which would result in a repayment of the investment after 2 years that continued for at least a 5 year period for a savings of 3 FTE over a 5 year period.

    Actually, you're right. Many of the Windows NT problems are related to application issues. (Of course, some would see this as an inherent weakness of the OS; depending on the circumstance, that may be a deciding factor.)

    I was recently at a Microsoft Partners function that was attended by three Windows 2000 developers. One of them discussed specifically the question of why Windows/IIS web servers needed to be rebooted so often. Here's (approximately) what he said: "We found that they weren't always rebooting because they needed to, but because they wanted it to happen under their control, not when the machine decided it was needed. When we examined the problems, we found most of them were within IIS itself, relating to locked files and non-terminating scripts. Under Windows 2000, IIS runs as a service that you can stop and start by itself without rebooting the OS, and you can schedule it to happen when you want."

    So, in essence, they worked around the problem by providing a more robust solution. Now you can schedule your web services to automatically shut down and restart themselves, without a time-consuming hardware reboot.

    I can say from using both W2K Professional (beta) and Server (gold) that it's far more robust than Windows NT 4.0. You could always achieve good reliability with NT by carefully limiting your choice of hardware and running only software that was needed, but that's no longer going to be as necessary. I still have my beefs with Microsoft, but reliability isn't going to be nearly as high on the list as it used to.

The upshot is that you're in trouble if you like to bottom fish for a completely different set of the cheapest components you can find on every new box you do. So, go with quality hardware, and try to standardize your boxes; or at least check beforehand to see if the ISA slot modem you're installing is supported.

    but at least it has friendly support (you people could work on this one), copious amounts of software, and configures with just a few clicks of the mouse button

    Well, I for one have found the free Linux support more friendly and responsive than commercial tech support I'm paying good $$ for. But, you have to remember it's free. This means putting your sweat equity into fixing your own problem first, and then taking the effort writing a clear and concise description of what you are trying to do and where you got stuck, with the minimum amount of bitching about how stupid Linux must be because you already know how to do this on Windows. In other words, make it easy and pleasant for someone to help you.

    If you come to the table with a chip on your shoulder (as users of commercial support feel they are entitled to do), then you will get your rudeness shoved right back at you (you might not be aware that you are being rude, but ask anyone who's worked tech support).

    So brush up on the charm. It used to be that computers were a haven for people too socially maladjusted to function anywhere else. No more!

      OK, here's where I look for documentation:

      (1) the "apropos" command, followed by the "man" command. The "apropos" command tells you the names of other commands whihc have the keyword you supply; the "man" command gives you the manual entry for a command. Sometimes you'll strike out here, for example trying to figure out what you need to configure Apache, "apropos apache" will give you lots of stuff you don't need, and none of what you do need. However, if you're wondering about how to track memory, "apropos memory" will tell you all the commands that mention memory, one of which is the very useful "vmstat" -- try "man vmstat" and you have a very detailed memory. With time, as you absorb Unix jargon, this gets better. For example, you might want to know about commands telling you what jobs to run, and strike out with "apropos jobs"; however, "apropos process" leads you to the very useful "ps" command (for "process status"). Man is where you go to find out all the bells and whistles for commands. Familiarize yourself with the command "grep", which will be useful in the next step.

      (2) the /usr/doc tree, where you'll find detailed descriptions of various software systems included in Linux. Especially, get to know /usr/doc/HOWTO/, which tells you how to do things like set up a DHCP server or how to turn your Linux box into a firewall. Think of this as Linux's answer to the "resource kit". Once you've mastered grep, and the "find" command, you'll find this a very fruitful place to look. Is working this way obscure? You betcha! But it works; almost always the answer you want is going to be found here, written in hacklish, to be sure, but its here.

      (3) the configuration files themelves offer guidance, once you figure out which ones to tweak from man and /usr/doc. These often contain documentation on what the various config file settings do, with examples all worked out -- just delete the '#' which turns the example into a comment. This is especially true with the sanmple Apache config files.

      (4) the home pages of the open source component being configured (e.g. www.apache.org). Note that Apache, for one, delivers its documentation as HTML files. A little problematic if you haven't got the web server running and you don't have a browser you know how to run installed on your Linux box. However, the documentation is, in a word, superb.

      (5) Books from O'Reilly with animals on the cover.
      Years ago, I learned Unix from osmosis, and a book called "The Unix Programming Environment". Any recommendations for NT converts? In keeping with the spirit of Unix documentation, I've listed this as 5 but this will be the first place you will want to look, unless even better you have a friend who's a Linux wiz.

      (6) The source code. I'm a programmer, but I don't much refer to the source code for most Linux programs unless I need to change it. However, it's nice to know the source is there and somebody could figure it out if they were sufficiently motivated. The answer to your problem is never a trade secret.

    Wow... I can't imagine how screwed up they must have set up to get those results..... I am sure linux is stable but I am also sure NT is stable......(not even talking about w2k which is rocking in the lab)... 68 times? You know - there is just no way this is done right.. I bet both of these OSes if set up properly are very stable.. the problem is that every "lab test" comes out with one of them being horrible and one being awesome - the truth is that they are probably both stable when set up properly...

    Well sparky, you obviously don't know what the hell your doing or your application sucks. Your going to blame NT for a crappy application now? Your also going to blame NT for the box costing $10k - HEY GUESS WHAT the same box with Linux is 9500 bucks! And hey, the $30000 application - I think MS has a rule that all NT apps cost 30,000... If you worked for me and I told you to deploy an application and you couldn't figure it out.. I would find someone who could.... 90 mins up time huh - thats pretty bad - sounds like maybe something is wrong because I am not aware of a 90 minute timer in NT for crashes. Get a clue, "sport"
