Cluster Active Active Max Memory Configuration

  • Hi,

    In my company i have active & active cluster setup on 2 nodes , have to configure max memory configuration 16 Gb RAM on Both Nodes and reporting server also hosting on same boxes, How to split max memory settings for both servers

    If i set max memory for both servers as 6 gb each,rest of the ram space will be wasted when 2 servers are running on different nodes there is any automatic script for max memory configuration while the server switch to other node

    Please let me know.

  • I would set them both to 12GB, for example, and if there's a failover, let them fight for the available memory. The reason for this is that failovers should be rare, and if they do happen, you would be looking to fail back at the first opportunity. Therefore, as you mention, why waste all that memory during normal operation for the tiny proportion of time that they'll both be running on the same node? I don't know of any scripts that will reduce memory automatically, but I imagine you could do it with Powershell or even a command script.

    Not Sure on automated script but you can certainly create alerts for it. Once you know that failover happened, you may reset Max Memory manually.

  • if there's a failover, let them fight for the available memory

    I agree with John if and only if the failover period is very small. If you are in Performance SLA with your customers, please don't go for it. This would be the period where end users can find out performance degradation very easily.
