What you are recieving is called "fear of the unknown pushback". If these same web hosting companies host customers ATX based Linux boxes then you know they are talking bollards.
1. WHAT IS AMIGA ONE?
2. Not familiar .
Well this is where I figure you have asked the wrong question or gone to the wrong people. If they have their own dedicated servers and do not host other peoples equipment this is a valid response. If not then this is a dumb answer.
3. Difficult to find components / spare parts.
Its an ATX motherboard dammit, if it breaks down you replace it. Off the shelf cards! Off the shelf hard disks!
4. Difficult maintenance.
5. Reliability
(sarcasm) Yes, because it is so difficult to switch off a running board, replace it and switch on. Reliability?!? Where are they sourcing this from? Reliability compared to what?
6. Impossible to replace parts without turning off the computer.
You definately talking to the wrong people :-D This is true of any *ATX derivatives.
7. Storage problem & Disk controller cards.
What storage problem? What disk controller cardS? What are they trying to do get this think to run a Shark array?
8. CURSES! (ie: Gateway, Soros, Kouri etc)
Well that is just silly.
The main problem is the storage (multi Terabytes):
You are asking them to just connect up YOUR hardware to THEIR network arent you? Not asking them to replace their rack mounted WTX based i-series servers?
A. Is there any Linux PowerPC SCSI or Fiber Channel driver for A1?
B. Does A1 need a special SCSI card with PowerPC BIOS on the card?
AFAIK there is a FICON driver and a SCSI over PCI driver in the latest Linux distros, no idea if it has been built into the PPC distros that A1 is using. Otherwise the answer is whatever you can get for an ATX PC you can get for the A1 ( although you might need to source a driver ). The point about the BIOS is silly.
C. Is there any Linux PPC support for RAID and Multiple Channels card?
Should be, worth looking.
D. What is the maximum hard disk capacity?
E. What is the best hard disk size and number of hard disk for optimal performance?
Who were you talking to??? :-) Clearly you didn't explain you wanted to host your own server. ?-)
