What limits the number of controllers inside a single PC? For example, if I do not care about enclosure, power, cooling considerations - and all the other superficial facts - what are the negotiable and un-negotiable limits on just how many drives may be attached to a single motherboard?
I was considering posting under the "Maximum drives limit attachable to a single Motherboard", but my questions is really about how to squeeze some cheap controllers and commodity SATA drives and not novel-enterprise hardware, because of simply the cost factors.
For example, I would even go as far as 1 USB CD, 4 IDE HDD and five SATA HDD as long as the USB CD boots - but would it work?
What limits this besides the superficial and the available expansion slots on the motherboard, the OS used, and what else? And no - no USB or FireWire or other expansions but drives attached directly to the system bus. SCSI, SAS or whatever is also enterprise and expensive, what are some of the other options?
How many and how did you manage to make work, please share! Nothing important depends on this for me, but I have a hard time piecing the BIOS, chip-set, IRQ, and all other factors together. Thanks!
