Using CENGN image from May/15, we observed that memory usage on virtual environment is no longer topped. i.e., a standard (2+2) configuration with a full setup: Controller-0 (Active) total used free shared buff/cache available Mem: 23G 4.6G 11G 48M 7.5G 17G Swap: 0B 0B 0B Controller-1 (standby) total used free shared buff/cache available Mem: 23G 1.6G 18G 10M 3.4G 21G Swap: 0B 0B 0B Compute-0 total used free shared buff/cache available Mem: 31G 601M 28G 9.3M 2.0G 30G Swap: 0B 0B 0B Compute-1 total used free shared buff/cache available Mem: 31G 554M 28G 16M 2.0G 30G Swap: 0B 0B 0B Even when we assigned 24GB/32GB to the VMs, the usage is considerably low. Thanks for the assistance on this.
