Hi
I have multiple physical and virtual database servers that we are migrating to AWS. To get my memory requirements I got the memory each database used and added that together. Based on that I was suggesting 4 servers at 244GB each. The company want to reduce this if they can. I know you can get the page life expectancy but is there a way to break it down to database?
I am not sure if each database needs the memory it is using and I guess I won't be able to test this until I go live. I don't want to under spec and then have the disks/cpu not being able to cope with the demand.
Thanks
