ASCHI cluster different RAM amounts per node

in my experience, it is possible to have nodes with different amounts of RAM in an ASHCI cluster, but it comes with some caveats. ASHCI generally assumes a balanced resource configuration for high availability and efficient workload distribution, so having nodes with varying RAM could cause issues during failovers or resource contention. If you increase RAM on just the SQL server host, make sure to test how VMs are scheduled and ensure that VM specific resource settings are in place to prevent over committing. Also if possible you have to closely monitor the system to avoid potential problems if the host with more RAM fails. While it’s possible, I’d recommend proceeding cautiously and evaluating the impact on your cluster's performance and resiliency first. Hope it helps!
