Well, if you think you're going to get high performance and super
redundancy on cheap hardware, you need to think again. ECC memory isn't
cheap either, but if you care about your data, you have to decide whether
it really needs to be protected.
No, you don't necessarily need fibre. Some people do this over copper-based
LAN links.
That is not what I meant.
For example if my DB is 2Gb large, I probably don't need 32Gb RAM.
The same way, if I can get a fast and reliable system with copper based
LAN and not Fiber-Channel, this can save some money that can be used
somewhere else for better use (CPU/RAM for example).
Currently I am not concerned with prices. I am trying to gather as much
information as I can in order to be able to give good "recommendations"
or advices when I could be asked for.
So there are things I can test (mainly softwares) but testing hardware
is less easy.
Thanks
Pascal
