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!
1Well since you think power and cooling are just superficial for whatever it is you're trying to accomplish with this question then the answer is: as many as you can scrounge up and connect to the MOBO. Your MOBO does not have a "Data-Storage" limit, only OS's do. As long as you can keep making the connection to the MOBO then you'll be able to keep adding storage devices to it. – Andrew – 2014-12-17T10:51:38.910
You are saying if I fill all the expansion slots with SATA controllers the BIOS might go crazy but Linux is going to be fine, or the BIOS will be fine as well as any OS? I do not have the money to buy controllers and hard drives to test and see, I only need to know if there is anything in the BIOS, chip set, PC-architecture or anything else which would disallow this..

@Reeves "whatever it is you're trying to accomplish with this question" On my own time and by my own resources I am trying to build a simulation of a production environment at my current employer, using a single box and a desktop - Semper fidelis! – arch-abit – 2014-12-17T12:48:51.723
My thanks to the moderators for closing this post of mine. I usually try to close my posts or delete them if they are too broad, but in this case the bottom line is as long as there is free expansion on the mobo the number of SATA controllers installed is only limited by OS support to read, and then write and use them. Thanks again! – arch-abit – 2014-12-27T05:44:00.513
