Case ID 00454092
Server 2012 hyper-v cluster environment. Production environment on Cisco UCS C240 servers with EMC VNXe Storage. DR Environment on Dell R710 servers with a Dell Powervault MD3200i.
Issue occurs in Veeam 6.5 and Veeam 7 (with update 1).
Server 2012 has all hyper-v and failover clustering hotfixes installed linked from http://blogs.technet.com/b/askcore/arch ... fixes.aspx
Veeam 7 is installed on a 2012 VM on both the production environment and in the DR environment.
Issue is when restoring a virtual machine the memory usage goes up by approximately 20GB which causes the production hosts to max out and make vms unresponsive. Can reproduce 100% of the time, issue occurs on both production and dr servers although as the DR servers are not as loaded memory doesnt go to 100% but still see up to 20GB increase in RAM usage. When performing a backup there is no noticeable problem on the hosts. When permorming a replication from production to DR i see memory usage on the DR side go up again.
Support have told me it is a known issue with 2012. I can see known issues with backups of CSVs but not restores. Would anyone be able to confirm what bug this is and if it is reproducible on their systems?
