Hi
Environment - HP DL580 G5 running 2012 R2 Hyper V
There are only 2 VM's on this box and the underlying storage is provided by Equalogic.
I have created 2 VM's running 2012 R2 Server with SQL 2012 Enterprise SP2 which are identical apart from one being generation 1 (imported from a 2008 R2 server) and the other being a native generation 2.
My issues is if I increase the memory to 20gb (runs fine on 10gb) on the gen2 server it will crash under load (dbbc checkdb or any other intensive operation). Gen1 server has no problems running at 20gb.
I am suspecting a numa issue but before I go down this route was wondering if anyone else has seen this. VMQ's have been disabled on both VM's
