I was interested to note that Dell > refused to ship a dual processor Precision Workstation with Linux. > They said that Linux wouldn't support a dual. First, we ordered dual process systems for a couple of reasons. First, we wanted to see if they had enough horsepower to replace our dual processor Sun SPARC Ultra 2. Second, we figured that we could "split" the systems in two pretty easily by purchasing a case with a motherboard that supported 450 Mhz Pentium IIs and moving 1 processor, 256 MB of RAM, and one 9 GB disk to the new boxes. >2.

If you decide to use IDE drives, then I would recommend writing your data to a separate disk. This way, when the disk fails (a lot more likely with IDE drives than SCSI ones) you havn't lost anything critical. >3. My local engineer is recommending Ultra ATA drives to save money. > do you know of any reason why they wouldn't be a good idea. Our experience is that SCSI drives hold up to hard use a log better than IDE drives (ATA). Again, if you configure the system to have data on a separate drive (or the data may reside on a different machine altogether) then IDE drives would make sense. I agree that they are a good place to save money: from CompUSA adds recently one can buy a 10 GB UIDE disk for $179 and get an Iomega Zip (100 MB) drive thrown in for free! Pretty hard to pass up a deal like that! >4. I think I would pass on swappable drives if only for security. Again, I wasn't recommending our systems. I was using them as a benchmark for what you can get. I see that one can easily purchase a 450 Mhz Pentium II machine with 128 MB of RAM, 13 GB disk, and a 19" monitor now for about $2000 (the monitor really bumps the price up). >Again thanks. You are welcome. Tom
