How much available memory is best practice for SQL servers? We have some alerts set up by our system admin, they go off if the available memory goes below 500mb. Which is fine for other servers but I feel for SQL server it isn't quite correct. Currently we stand below at about 475mb and the PF usage is around 7gb.
It is SQL 2005 standard SP1 x64
dual intel xeon 5160s
8gb physical memory
buffer hit cache is > 99%
I am just not confident enough to make a solid decision here that this is acceptable. In the beginning of this month I ran some counters for 24hrs to get a feel for the baseline. The average for available memory was about 850mb at that time. So I am wondering if it is going to keep declining and turn into a problem. The server/instance has not been restarted since maybe last November.
thanks
