Physical Memory Percentage Use on Windows Server 2011 SBS

I installed the server component of an app on a newly re-formatted Windows Server 2011 SBS machine yesterday. I found the server pretty slow so I checked the machine a bit. The box has 8 GB of RAM. The physical memory percentage being used was in the 85% area.

The server is running Exchange Server, which I believe uses a lot of resources... The app I installed uses SQL Server Express 2008 R2.

I am an applications guy, not a server guru. Is that normal or should additional memory be installed in the server?

Thanks very much,

John

With SBS servers, there are a lot of built-in applications like Exchange. SBS always has high utilization because everything is bundled together. It also take a resource hit from anti virus. You might want to see if there is an AV scan running or other app that's taking memory.

Open task manager and sort on memory utilization and then on processor utilization.

8 GB of is the bare min required for install.  You need at least 16 and my recommendation would be 24 since there is an additional app running on the server

I agree with Chris Hanna, 8 Gigs of ram in any Windows server 2008 or newer is a minimum amount.  If you check task manager, you will probably see Exchange taking a large portion of the memory. depending on your SQL app, it could be using the rest. if you are running an anti virus app, that would be another item to check.

Post what task manager sows on memory and cpu usage.

I suggested 16 GB also, but it's an old box that was reformatted and memory cannot be added! Penny-wise, pound foolish!

Exchange was taking most of the resources of the server.

They will buy a new server in a couple of years and accept the limitations of their current environment.

Thanks very much,

John

To the author...you can limit Exchange  memory usage to help the situation.  By design, Exchange will use as much memory as it can get it's hands on.   Give this a go

Yes thanks TG-TIS!

Cris: I'm a CRM specialist, not a network / server specialist. Their network consultant did not take kindly to some of my suggestions ... so I will let him take care of the server and I will keep their CRM running!

Best,

John

I hear ya.  I'll bet if anyone looked at the hardware the server is running on, it's probably a desktop, especially since it won't handle more than 8 GB of RAM
