How do you setup SCSI Drives?

[OverVolt]

Hey Everyone!

I'm lookin to make a new system, and thinkin of going SCSI since i have a little extra money. I thought about it for awhile, and realized i'm so used to IDE drives i never worked with SCSI before. So Just wondering how you setup SCSI drives.

I know a little, like 7drives per controller, i think the controller itself takes a spot, not sure. Anyway any help would be good! Thanks!

Here's a good place to start.

Any more questions, send a PM to Mastertech01. John's the SCSI king!

SCSI supports up to 8 drives per channel minus one for the controller, most SCSI adapters are 2 channel and I know that you can have 15 drives with 2 channel. Don't quote me on that but I know that you can have 15 drives on a 2 channel controller. Anyway You can get Ultra 320 SCSI controllers for $300 or so for a dual channel and i think the single channels with smaller buffers can. Do you want to do RAID with your SCSI drives? Adaptec sells a 0 channel raid add on card for $200 which you can add to a standard SCSI controller to add raid 0 function. If you are looking to do a raid function that requires XOR like RAID 5 or 50...get ready to spend $800 for a controller card.

If you are not using raid the only thing different you will need to do is pay alot more for your drive cable and load the SCSI controler drivers while installing your operating system.

If I had extra money to spend I would throw down $550 and buy this board:

X5DA8 Dual XEON 533/400FSB

Dual xeon board with onboard ultra 320 dual channel scsi, 8x agp, dual channel ddr (ecc only)

Very nice!

Set the hard drive's jumper so its ID is 0, or some other number that's not already in use on that SCSI bus. Plug it in at the opposite end of the cable from the SCSI card, right next to the terminator. In general, that should do it.

If you're installing Windows on it, you'll need to have the card's driver on floppy and press F6 when prompted at the very beginning of the Windows Setup routine. After getting Windows installed, you'll probably need to go into your BIOS and set the mobo to boot from SCSI, naturally.

all of the number of devices per controller information is wrong is this thread.

one controller - 15 IDs for 14 devices, (the controller itself uses one id.)
two controllers - 28 devices.

assuming LVD operation and parts, set your drive to ID 0, and place it on the cable between the active terminator and the controller. that should be all you need to do, if you boot off the scsi, change the boot order in your bios (make sure the scsi bios is set to boot to id0 if it isnt already)
