  1. The Actual Results on Ask Slashdot: Is SMP worth it? · · Score: 1

    I was running on a dual Pentium Pro 200 (with the 512k cache chips), and was sold on scrapping it for a singular PII 450.

    Guess what?

    The dual Pro setup blew away my PII.

    Everything ran significantly faster, I could FEEL THE DIFFERENCE. Also, there were no lags whatsoever. I could run mathematica while compiling a new kernel or OpenGL program, without noticeable lags.

    And unfortunately I sold the entire old system to a customer, who is running Novell 4.11/SMP on it and would rather 86 me than ever switch out the machine. I recently priced those chips and they're still over $900 each. Explain that.

    But, here's the glitch:

    I also have built dual Pentium systems (not PPRO), and the chips don't seem to scale as well... Does anybody know why? Internal architecture, what?

    Here's my advice:

    If you want to SMP, do it with a real chip, or not at all. Buy 1 of the PII 450s, get a dual board, and run 1 processor until you can afford the second one.

    Better yet, do it with a Xeon.

    (and the whole thing is senseless without ultra wide scsi, I use the Seagate Cheetah, and it makes a major difference).

  2. If you need to ask... on What do you Need to Start an ISP · · Score: 1

    Firstly, if you need to ask how, don't even bother. You already lack the ability, and would pay out a small fortune for your mistakes or
    the advice of a good gu.

    Secondly, these days it only makes sense to break into this new if you already have the capability, and want some return on your invest. For instance you have a huge lan with a commitment for several T3s from sprint (or whoever), are a cable provider with 1000's of subscribers, and want moolah. My advice is if you are not Sysadmin already on a huge unix network, you will be sorry. You will simply not know the nuts and bolts of how to get it up, and clueless what to do when the boogeyman cometh.

    If you do decide to do this you will have a really hard time finding the area that does not have oversaturation by other ISPs or the big
    ones (AOL, MSN, WORLDNET, ETC).

    All_negativity_aside::ISP

    2 T3s or you will never bust even.
    Some decent CSU/DSU Router combo(Cisco, livingston, nile, etc).
    BSDi or SunOS (get the enterprise 10000 if you $)
    3Com 3900 switches.
    UPS equipment hung on the ethernet(APC with SNMP).
    HP Datatank AL or equivalent tape system.
    Rack Mount servers or USR Edge Server racks.
    Duplex everything and use seperate boxes for name server, mail server, web hosting, etc.
    Some admin stations. P200s or better, for staff.
    All this stuff with 3c5x9 NICS to the 3900 switch.
    (I have a gigabit link from the switches to the servers, but am serving large corporate WAN). Comdial DXP (with voice mail integration) and DUs.
    SNMP console software (Openview in my case).
    ISP Accounting software, or write it yourself.

    Advertising.

    And a very big and long fire hose, lots of excedrin, and a do-it-yourself Kvorkian kit.

    Good luck, you are now a time-slave.

  3. 2.2.1 with ROCKET FUEL! on Kernel 2.2.1 RPMS · · Score: 1

    Hey, just follow the instructions, upgrade the modules they have, make the bootdisk for safety, (personally I always have a way to back out in LILO), and download the tar file from kernel.org.

    It was a cake walk. And guess what?

    I realized after building and booting it, that I did not remember to back out of PGCC and use gcc.

    HA HA HA. My kernel is screaming and its compiled with

    pgcc -06 -funroll-all -mpentiumpro -march=pentiumpro -fno-reduce-strength

    I made it with the make bzImage and it never even hiccupped.

    Im on a pII 300 with 96M and a 8M Matrox MII. Ultra Wide Cheetah drive. I did have to make a initrd-2.2.1.img for my aic7870.

    Rocket fuel 'o kernel. I am a satisfied customer.

    Thank you Linus, Al, and all involved. It was worth the wait.
