Sizing Recommendations
Use the sizing recommendations below to properly provision your Device42 Main Appliance, Remote Collectors (RC), and Windows Discovery Service (WDS).
Sizing requirements depend on the size of your environment and the Device42 features you use.
| Device42 Item | Sizing and Notes |
|---|---|
| One Main Appliance (virtual appliance) | Small to medium environments (<2500 devices): - Four vCPU - 16GB RAM - 150GB vDisk (SSD or flash disk recommended) Medium to large environments (>2500 devices): - 16 vCPU - 64GB RAM - 150GB vDisk (SSD or flash disk recommended) For any environments that include Application Dependency Mapping (ADM), Resource Utilization (RU), or Storage discovery, follow the medium to large environment guidelines |
| Remote Collector(s) (virtual appliance) | One RC per 1000 workloads: - Two vCPU - 4GB RAM - 50GB vDisk |
| Windows Discovery Service (.NET installer) | One WDS per 1000 workloads: - Two vCPU - 8GB RAM - 50GB vDisk (minimum) |
Recommendations
The following are general recommendations, but the optimal setup depends on your specific infrastructure. Contact support for more guidance.
RC for Large Workloads
First, increase the CPU and RAM when adding more workloads (> 1000) to the Remote Collector. If the Remote Collector is still performing slowly, add more Remote Collectors.
Dedicated Resource Pool
Depending on your environment, a dedicated resource pool for the virtual appliance may be necessary to ensure there is no resource contention.
Database Storage
Device42 uses a database within the virtual appliance. Solid-state storage, or similar storage optimized for database operations is recommended.
WDS Installation
For Windows infrastructure, Device42 requires a WDS to be installed on one machine per discovery segment or Remote Collector.
