I'd like now how to better understand the memory utilize by sql server. I have done some continues statistics and using monitoring tools and it seems that in some of my servers I see a constant high memory usage for both the OS and the SQL Server memory. In some instances the sql server memory reaches 95% and stays to that under for several hours.

Any ideas where I can start reading and understanding what it all means and how to figure out what's causing the high memory usage?

Thank you.

Normal, expected, documented behaviour.

It's a combination of different servers, production, test and dev. I'm new to this job and I'm learning what to expect from this systems but I know that at least on the dev server we don't get much activity going on on some days but we still see high memory utilization on both sql server and os memory. The link seems to be a great starting point. I'll review it.

Thank you.

Again, that is normal, expected behaviour.
