What this term mean "TempDB should have one data file for each CPU"

I would have thought someone as talented as you would know this.... 😛

It is best practise, to have one file for tempdb for each cpu.

there are other articles that also explain it, but this one is ok.

I know that its a best practice but actually at one point of time I came across with somebody and the way it was written confused me a lot something like that:

data file in TempDB = #CPU :w00t:

the reason I asked this question is to make sure if there is any other term exist which I don;t know. 🙂

so I. but thanks for reply.

BTW did you ever come across with any situation where in A/A node the number of CPUs are not equal on both nodes?

Nope but I have tended to work with only 2 node clusters, normally the servers would be identical in spec. for bigger clusters or for multiple sql instance clusters, it might be different.

I could be wrong but I have heard that windows 2008 clustering the hardware can be different, but on windows 2003, the spec has to be the same.

Also remember that they all need to be the same exact size for the algorythm to work optimal.

yeah , that has to be but under different environment where lets say servers has different numbers of CPUs. how exactly the TempDB configuration can impact after failover.
