A well known company recently presented data which suggested that only 20% of unplanned outages were down to hardware problems, 80% was down to operator error, O/S problems and running software. And I might add that this was a software house, and not a proprietry UNIX vendor. It's certainly my experience that most f*** ups could be avoided by not logging on. It's also my experience that it's the network which has the most problems, followed by moving parts (disks and tapes). Therefore dual attaching to the network, and RAID would be vital if you wanted to minimise outages. And make sure the users only have the rights for what they need to, including yourself. Sitting as root all day will inevitably lead to a slip at some point! At 21:48 16/02/00 +0800, you wrote:
I am a hardware oriented person, that's my cup of tea.
The philosophy I hope to success is: If the hardware is bad, no matter how good the software or OS is, its just going to fail.
But, how many system (software) implementor on this planet really know hardware? by reading this list, we may be able to conclude that some of the problems are caused by some 'not so compatible' hardware mainly due to design or QA control of the manufacturer.
I believe Linux can be used for serious work if you have the proper hardware. Cheapo or unmatching hardware simply not going to hold this promise. Agree?
A real person should solve the problem instead of avoiding it, if not, someone else will. Agree??

There's a belief among a lot of old Unix hands that commercially developed systems are more reliable and perform better than Linux.
One thing is that Linux is delivered on cheap hardware, which is not designed to be as solid as those machines for which there is better bus and memory CRC checking, and such other things. This hardware being meant to be more dependable, people also believe stronger in their systems.
The Linux machines I used are very dependable, or so they seem. I'm lucky, and most of us are. However, I have some friends who had intermittent memory problems, or other difficulties, which are seemingly hard to diagnose precisely. We just speak of "cosmic rays", then :-). A bit irritating for them, but bearable nevertheless.
Real people do not take such risks as running important programs on Intel machines. Unless they also run Windows-NT on them, of course :-) :-(.
