    Sca: Scsi, Sata, Ide

    http://www.supermicro.com/products/motherb...E7505/X5DA8.cfm DUHHH!!! I have a dual channel, 320 scsi motherboard. I can connect, and I have picked up, SCA in scsi, SATA, and ide. First two are Supermicro, the last is the one my local computer shop has. Drives per channel, and device, is not at issue, since I have two on board controllers supporting two drives per channel, another 29160N card supporting a burner, cd, a reader cd, a dvd reader, a floppy, and, a Zip drive. I'm thinking about moving my Quaxtor 160 gig to a mirror, off an ide box. s
  2. Vidmar: You bitch!!! How dare you interject fact, and actual experience, with the amount of garbage posted in this post. SCSI raid arrays, and the quality of the components, are simply in a different league. The controllers, the drives, and the cables, are all much better in scsi then in SATA, etc. I have 4 X 15's, only generation 2's, in raid 0, on an adaptec 21010S. They are around 110 mb sec, or more, with the 64 mb cache. Going from 3 to 4, on a dual channel setup really helped, and, suffice to say, this setup rocks. While not your common solution, I use a Supermicro X5DA8, with 2 Xeon 2.8 ghz processors, XP pro, a gig of ram, onboard sound and Klipsch, and a Matro P650 for gaming. I might try the virtual program for disks, since I believe ram is the best place to store, and access, any info. Or, I might add a gig of ram, to the one I have, soon... s

    Hi I need a large capacity, reliable, redundant storage solution. I want to buy a SCA hotswapable box, for my 17 drive case. What are the merits of each of the avaliable interfaces, for mirror one storage? Thanks gs

    SCSI vs IDE specific example

    The King is beyond the princess and the pea when it comes to noise. I, on the otherhand, can't hear 4 X 15's, two feet from me, thanks to a very loud fan, on the cpu. None the lessit's a quite roar, most couldnt' hear, and I really can't. gs

    Resurrecting an old mac g3 333mhz tower

    The computer is used for burning, using the Tempo card to firewire, scanning, using Photoshop 4.0, and OCR, using Carere's OCR software. Plus some simple book keeping stuff, and, maybe, internet access through a hub. Problem is, I have THOUSANDS of dollars of OS 9, or lower, software, and, I don't really feel like rebuying it, on a teachers salary. I'm having good luck with 8.6, and may move back to that, now that I can use my 1200 dollar Nikon scanner on it, rather then throwing it away. It won't work under 9.22. I've already ordered an X 15, and, an oem UL3d ATTO card, and I'll hook one up, to the other, and hopefully the X15 will be right at the limit of LVD, and the grackle chipset. I've been able to run both photoshop 4.0, and Toast at the same time, with 384 mb of ram, under OS 9. While I have PS 7 for OS X, and Office, why should I move to another system, one step out of the IT setup for our school, and district? I like OS X, and may install a Raptor, just so I can boot into OS X, but, I'm firmly in the scsi camp. IS the Ul3d bootable in OS X, or is it IDE only? gs

    SCSI RAID 10 w/ 4 15k drives?

    I use 4 X 15's in raid 0, for 110mb/sec. gs
  7. HI My new school district is all macs. So, to get things going, I brought out my g3, 33hmhz with 9.22, Cheetah 10x on an uw card, using an LVD cable, and termination. I bought a Tempo 3 in one card. It has four fire wire ports, 2 usb external, and, it looks like two ide 133 channels. Install card, dead machine, no boot. Switch slots, putting scsi furthest from processor, everything works fine. Don't ask me why. Just a guess from playing with PC's. So, I reinstalled my mouse, and scanner, on the USB ports, and a La Cie firewire, cd-rw for burning copies of programs, for class room use, and, plus a scsi reader, external. I ordered a LVD ATTO card, and, I'm considering ordering one of the 15.3K Cheetahs, 18 gigs, 3.6 ms, access time, for a boot drive. I'm also wondering if anyone makes removeable ide drives that I could plug in, or, if I should just get firewire drives, and use those for data backup. The grackle chipset limits the bus to 75 mbsec, about right for the new X 15, and the 32 bit/33mhz bus limits firewire to 40 mb/sec. Another consideration is getting a raptor, booting os X, and going on from there. The problem is OS X may not support my scsi stuff, but, I think it will, with the ATTO card, and boot from the Sonnet, since I don't think the ATTO card is bootable in OS X, on a beige. Any thoughts, comments, etc.? Thanks

    Best SATA RAID PCI controller?

    No choice. LSI. If you wait, the price will go down, capacity up, and warranty probably will be 3 years. Anyone tested these cards, to find out how well raid 1 works, or raid 0? gs
  9. Great. Give it a try, and let us know what you think. gs

    Q about SCSI

    Does a 29160 do hardware raid, or are you doing software raid? Post all specs on your system, and what you are going to be doing on the system. GS

    Will RAID 0 make a difference for me?

    I'm pretty much completely set on not over-clocking. I've done it, with limited success, and, I just don't find the increase in speed worth the possible loss in longevity. Depends on what your replacement time is for each machine. In other words, if you can rebuild, at minimal cost every year, more power to you. If your chip wears out, due to increased voltage creating heat it wasn't designed for, no big deal for you. I'm on a 3 year plus cycle, and when I do it, I want it to be a wise, well thought out, well planned upgrade. Guys I listen to generally are buying for mission critical, major companies, and think the same way I do about my own stuff. I will say that the next time I do it, it's going to cost a lot more, and be a major upgrade in box, powersupply, motherboard, chip, ram, and processor(s). If mid 2004 is a goal, for the new intel stuff, then I better start saving my nickels for that event. gs

    Will RAID 0 make a difference for me?

    Well, let's see. There is a point where you get diminishing returns for money invested, when you just want the fastest of everything. I've found, that as you increase ram, and you increase processor speed, the affect of the drive speed is diminished. I have little doubt that a Raptor, or a Cheetah, are the way to go, at least for me. However, I would suggest this is a strange time. SCSI has been around, and been stable, for a long time. That' seems to be changing. SATA may turn out to be as good, if not better. Smaller cables, easier to work with, etc. The other problem is finding motherboards to work with your drives. Here is my conclusion on the subject. I would look at either Tyan, or Supermicro, or Intel, motherboards, server quality for a new system, if I was going to go scsi. I think right now is an awful time to buy a new system, since new chips are on the horizon, and I would wait for the new chips, and motherboards, and the new chipsets that come with them. Plus, I found it would have been more cost effective to buy a bullet proof SM board, with onboard scsi, then add a raid card, then buy the raid card I have. If you want money no object, how about a solid state boot disk? gs
  13. Eugenes answer to your question:
  14. HMMM. You have bought an excellent card. I thought they were great at 140 bucks from Dell, used. Adaptec can be spotty, but I have had NO problems with the 29160N. Good choice. The major objection to scsi is usually price, but you seemed to have dodged that bullet. I'd go for the drives, and see if you like it. Good cables can be expensive, too. I've found that cheetahs work very well for desktop systems. According to Eugene, that must mean the algorithims and firmware are setup well for desktop use. Your major advantage with scsi is the components are higher quality, designed to last longer. I like to use coolers on my drives, as added insurance. I do use a couple Quantum LM's in other machines everyday. They work well. If you aren't happy with the speed, you can always buy one of the 3 current super fast drives, and have the fastest drive around, by quite a bit, and use the other two for storage. Actually, if it was me, seeing as you have already bought the controller, I'd go for the fastest drive avaliable. I think they are 250 or so from hypermicro. If you want speed, that's the way to go. A long time ago, I installed an old, POS IBM drive in a desktop, scsi, and started a real flame war. It only moved at about 16 mb/sec, but it was still relatively snappy compared to the ide drives I had at the time. Perhaps scsi drives, with firmware optimized for servers(many random reads?) work well for desktops, that tend to do the same sort of work? I also wonder about this statement: Finally, your system is a major component in speed. As your computer chip gets faster, and you have more ram, the speed affect of the hard drives diminishes. In other words, the faster the system, the less noticeable the effect of changing hard drives becomes. The most ram I've worked with is 512, and I've got that in two of the machines I work on, and 384 in the other, that's with Windows 2000. I'd like to try a gig of ram, but, I think, given the ram pricing, I'd be better off moving up to a Xeon system, with a gig, or more of ram. Maybe later. By the way, the reason I buy scsi drives is reliability AND speed. I've still got the first generation cheetahs I bought, and I use them for backup, in an external raid box. They are pushing 7 years old. I figure the time I've saved in not having drives fail, and reinstalling, is worth the extra cost. Don't do this half ass. Get the fastest drive on the market, or the Cheetah 15.3, and see what all the fuss is about. I've rarely found anyone that is disappointed by Cheetah's as far as speed goes. And, if you are, then you can buy another cheetah, and a raid card.... s

    Power Mac G5 shipping!

    And apple misleading it's customers is NEWS??? I think temperance is wise, to see how these machines work. Usually apple does something like put an ide chip capable of only 16 mb/sec on an interface listed as 33 mb/sec industry standard. How about a motherboard chipset that limits data transfer to 74 mb/sec, when the PCI bus should be able to go around 120 mb/sec? Lets wait and see what real world people find out about the macs, after they are shipped. First versions of macs, new models, generally are buggy anyway... s PS I would love to have a dual processor Xeon system, despite AMD's slight speed advantage.
