Memory Utilization

Dear all,

One of the server is having 2 GB of RAM and task manager is showing 1.87 GB memory in use.

I have to migrate few databases on the same server.

With high IO Operations.

I know server require more RAM, but how can i prove that server needs more RAM ?

Regards

To 'Prove' it, you need data. These articles will point you in the right direction to get some data.

You can look at some easy PerfMon counters, such as Buffer Cache Hit Ratio, Page Life Expectancy, and Memory Grants Pending to get a better idea about whether you are seeing memory pressure. Memory pressure will also cause increased IO pressure.

Generally speaking, you can hardly go wrong by adding more RAM to SQL Server, especially if you only have`2GB of RAM installed.
