# VME Manager sizing

VM Essentials manager can be deployed via the console as one of three predefined sizes: small, medium, or large. The greater the capacity, the greater amount of resources and cluster sizes the VM Essentials manager can manage. For large production environments, it’s recommended you select a large manager.

**Manager VM sizing options**

|  |  |  |  |
| --- | --- | --- | --- |
| Size | vCPUs | Memory | Use Case |
| Small | 2 | 12GB | Testing environments, small clusters |
| Medium | 4 | 16GB | Standard production, moderate workloads |
| Large | 4 | 32GB | Large production, high-performance environments |

**Performance guidelines**

**Small configuration:**

- Maximum clusters: Up to One (1) HVM cluster
- Concurrent operations: Limited provisioning
- Recommended for: Development, testing, proof-of-concept

**Medium configuration:**

- Maximum clusters: Up to Three (3) HVM clusters with moderate VM density
- Concurrent operations: Standard provisioning and monitoring
- Recommended for: Production environments, typical enterprise use

**Large configuration:**

- Maximum clusters: Up to Ten (10) HVM clusters with high VM density
- Concurrent operations: High-volume provisioning, extensive monitoring
- Recommended for: Large enterprises, service providers, intensive workloads
