Windows server 2012 standard max ram free. What are the system requirements for Windows Server 2012 R2?

 

There only time I might give a file server more than 2 cores is if it is very busy doing a lot of DFS Replication. The most important variable is number and type of drives, and RAID type. Windows Server is just an Operating System. It can run on a normal desktop PC.

I looked for a response to you, not to him. The is just a semi arbitrary ballpark estimate for a fairly large size database to still be using Standard edition. Therefore if you set your max server memory setting to 96GB SQL Server can actually use all 86 for caching data and still have 10GB to play with for plan cache and other items it needs memory for. Hope that clears things up for you homie. Is there a specific proportion or formula that you use when you are designing a VM in order to come up with these numbers?

Norbert, please correct me if I misunderstood you, but I was curious myself. If I need 64GB for data cache, how much do I need for everything outside this, such as procedure cache, metadata cache, etc? Procedure cache alone can be fairly substantial on some systems.

Query workspace memory grants can also consume a lot of memory. What I'm leading you to is use proper monitoring to diagnose performance problems. You need to know a lot about SQL and a decent amount about Windows to do this.

If you're not a DBA, hire one or get one in on a contract, or work with your software vendor if this is SQL for a purchased product. If it's something your company wrote itself without a DBA, go get one. By default, a SQL Server instance may over time consume most of the available Windows operating system memory in the server.

Once the memory is acquired, it will not be released unless memory pressure is detected. This is by design and does not indicate a memory leak in the SQL Server process. Although I'm not a system admin, it seems to me that sql server is using up little memory because everything else is being consumed by Windows. You're almost definitely wrong here. The amount of RAM in use by the sqlserver.

The DMVs and perfcounters will tell you that. Even simple things like opening the tables pane to see all my tables take a while and sometimes times out.

Task Manager will not show this. Your assumption that almost all of your memory is used up by something else and SQL Server is thus unable to use more than The following table specifies the limits on physical memory for Windows Server Windows Server is available only in X64 editions.

The following table specifies the limits on physical memory for Windows Server R2. Windows Server R2 is available only in bit editions.

If the memory is remapped, X64 Windows can use this memory. Sign up to join this community. The best answers are voted up and rise to the top.
