Hi,

Just wanted some advice on best practice for database locations based on my server config.

c:\ System raid 1
d:\ logs raid 1
e:\ data raid 5

Now I know the raid config isn't idea I can't change this.

The server has 4 physical cores and 8 if you count hyperthreading.

So I was planning to split the temp DB data files up fo the numebr of cores. Should this be split into 4 or 8?

I was planning to move the system DBs off the c:\ where they were installed by default and placing them on the same drives as the user DBs

Should I split the Temp DB data files accross drive arrays?

In an ideal world I would have a nice raid 10 config on it's own channel for each and every db but I am stuck wiht the server as it is.

So how should I distibute my DBs for best perfromance.

Cheers D

The transacion logs are in simple mode. Could we change the log drive to raid 0?
