The following tables detail the minimum resource requirements for a single-node setup of Cisco UCS Director. Cisco recommends a single-node setup for installations of up to 5000 VMs.
For optimal performance, the entire memory and CPU allocations specified in the table below should be reserved. Failure to
follow these specifications could affect performance. For example, 4 vCPU cores with 3000 MHz and 16G of memory must be reserved
for the Cisco
UCS Director VM.
The minimum memory required for the inframgr service is automatically set during deployment. To enable the inframgr service to use more than the minimum required memory, edit the inframgr.env file available in the following location:
/opt/infra/bin/
In this file, update the MEMORY_MAX parameter to the value you want. To activate the changes, restart the inframgr service.
The default memory settings are MEMORY_MIN=8192m and MEMORY_MAX=8192m.
For information about minimum system requirements for a multi-node setup, see the Cisco UCS Director Multi-Node Installation and Configuration Guide.
