FortiManager 3750G
Centralized management for up to 10,000–100,000 devices and VDOMs
- Devices / VDOMs
- 10,000–100,000
- Sustained log rate
- 150 logs/sec
- GB / day
- 10
The FortiManager 3750G manages up to 10,000–100,000 devices and VDOMs with a sustained log rate of 150 logs/sec and 10 GB/day of log throughput. Policy packages, provisioning templates, firmware rollout and a full change-approval workflow with revision history and rollback.
Ten thousand to a hundred thousand devices and VDOMs, 24x 16 TB of storage. This is carrier and very large service-provider scale, and the two-order-of-magnitude range on the device figure means nobody should order it from a spec sheet. If you are genuinely in this territory, the sizing exercise is a design engagement rather than a model selection.
Highlights
- Manages up to 10,000–100,000 devices and VDOMs
- Policy packages and shared object database across the estate
- Full change-approval workflow with revision history and rollback
- ADOMs give per-tenant administrative separation for service providers
Typical deployments
- Carrier and national-scale managed security services
- Deployments measured in tens of thousands of managed VDOMs
- Environments where management itself is a tiered architecture
