We all (should) know that running SQL Server in hyperconverged virtual environments, both on-premises and in the cloud, has some interesting trade-offs. The biggest is write latency from the hyperconverged storage platform underneath the database. We find that write latency suffers compared to traditional all-flash storage, even if the hyperconverged layer is all-flash as well, due to how the hyperconverged layer handles the larger block write that the SQL Server engine drops on it.
Read on for a trace flag which could help here.
