W2012 R2 VM with 16vcpu and 128GB Ram and enabled dynamic memory and Using SQL 2012 with Resource Governor enabled to create a multi tenancy SQL Database service. Dynamic memory is used to cater for local Site Hyper-V host availability.
For Hyper-V virtualization have read the dynamic memory and Fixed memory designs for memory management for SQL 2012. My understanding is that SQL 2012 dynamic memory is fine as long as the correct configuration is applied for both SCVMM hyper-V and SQL 2012
memory settings.
Enabling Dynamic Memory with SQL resource Governor will this cause an issue? So far tests it has not but I have not seen any documentation or discussion on this. Is there an extra overhead in the SQL engine as it acquires the memory as part for that specific resource pool for example.
In short is best practice for using SQL 2012 Resource Governor enabled --> Is it Fixed memory or Dynamic Memory?
