I am facing the situation mentioned here.
http://blogs.msdn.com/b/psssql/archive/2009/06/05/sql-server-and-large-pages-explained.aspx
My SQL Server 2012 is not able to use all the 112 GB RAM that was allocated to it after enabling -T834.
This was not the case earlier. Now I see the Total server memory and target server memory counters are just 27 GB constantly. I found the below error while starting SQL after enabling -T834. I restarted services again and this time it started fine. But I
didnt bother about the error untill users complained slowness and SQL memory usage was found to be low.
Detected 131068 MB of RAM. This is an informational message; no user action is required.
Using large pages in the memory manager.
Large Page Allocated: 32MB
Large page allocation failed during memory manager initialization
Failed to initialize the memory manager
Failed allocate pages: FAIL_PAGE_ALLOCATION 2
Error: 17138, Severity: 16, State: 1.
Unable to allocate enough memory to start 'SQL OS Boot'. Reduce non-essential memory load or increase system memory.
Now, SQL is started by its Total server memory is only 27 GB. How can I make SQL server use all the allocated max server memory with -T834 still on ?
