Memory (RAM) Increase for Large End User Capacity

Performance on a VOSS-4-UC installation with less than 16GB RAM may degrade when a large end user capacity is reached.

Memory on unified nodes of a cluster with a database role should be 16GB.

For each site with a multinode cluster, for each non-primary database server:

1. Shut down the non-primary database server.
2. In VMware, increase the memory for each non-primary database server node at the site as follows:
   1. In the Inventory panel, select the virtual machine.
   2. In the Hardware list on the Summary tab, select Memory > Edit.
   3. On the Resources tab, Memory > Resource Allocation and ensure the minimum allocation is 16GB.
   4. Click OK.

4. Restart the database server.
5. Repeat the process described above for the primary database server.
