Keep It Clean
I have just been asked by a client whether he should consider swapping out his UNIX box for a couple of NT machines to run his OLTP IDS system, given the seemingly large difference in cost. I have asked him to bear in mind minor things like resilience (!). Anyone out there want to add some weight to the argument in favour of UNIX (assuming, of course, you ARE in favour of UNIX) - remember the subject of this posting, though !

Am I correct in thinking that IDS on NT cannot use RAW disk ? Also, although the initial hardware may be cheaper the extras to maintain the level of performance Unix gives will probably make NT a more expensive solution in the long run.

What about Linux? I haven't used it in a production system, but it is the most popular Web Server OS. I would think that its only a matter of time before it becomes the most popular small-medium system OLTP OS (Well, I hope so :)) Rudy Mister Creosote wrote: > I have just been asked by a client whether he should consider swapping > out his UNIX box for a couple of NT machines to run his OLTP IDS > system, given the seemingly large difference in cost.

NT do not have RAW disk in that sense as Unix, but as far as I now NT can achive the same advantages using NTFS. I know NT quite well and have switched to Unix so I would like to tell you something about my experiences. I like Unix because of his possibilities for remote admin. I just need a modem-line to do whatever I like. On NT there are some admintools, which support remote admin, but unix do not need it, because I can log in via telnet. Performance is on same hardware normally better on Unix. If I want to save resources I can for example switch GUI off. Unix can be configured much more precise for the needs I have for that specific task. On Unix I have many powerful tools for administration and automating admin tasks (shell, awk, cron, grep, perl, ...). These are hard to learn. On NT you have some tools which are much easier to use, but with less power and possibilities. To say something good about NT: You can probably find more (and cheaper) people, who can admin NT. The GUI is the best I have seen (thats my opinion). On Unix you can find some good GUIs (I use KDE), but there are no standards. I'm sure you get a high uptime on NT, if you do not do anything else, but one database. NT can get less stable if you install a application, because this can affect system-DLLs. NT runs on cheaper hardware as most Unix-systems, but you can use SCO UnixWare 7 or Linux if you don't want to pay for propriatary systems. In the long term NT gets more expensive as Unix, because of admin-costs (TCO) and you get maybe less reliability and shorter uptimes. Tommi Mäkitalo
In article <8ccc53$bi5$1@nnrp1.deja.com>, I think that if performance is the issue, there are several things to consider. You can buy cheaper hardware for NT, and therefore spend the same amount of money for faster processors (for example). This is because on most UNIX OSs, a 300 MHz processor costs X dollars, while a 500 MHz processor for NT costs the same X dollars. (these are just made up examples) Second, UNIX runs on a much faster kernel than NT, which offsets the cost somewhat. The cost of administrating NT is less, but the remote admin tools for UNIX offset this also, in my opinion. Lastly, while both OSs support multiple processors, there was a white paper published a while ago (sorry, I can't give you a link), that described the benefits of installing multiple processors on both OSs. On UNIX, they noticed an 80% increase in performance for adding a second processor and every processor after that, while on NT, they only got 50% for each. Therefore, the hardware may be cheaper, but you also get less benefit from it. One other thing, I really hate the fact that on NT, if you change something on the system (add a new NIC card, etc) I had to reinstall the latest service pack before I rebooted or the machine wouldn't come back up and the emergency disks did me absolutely no good.
