# Size the host

> Host specifications per Collector and when to add another.

These figures are per Collector, on typical host specifications:

| Host                                                    | Comfortable             | Stretch (relaxed poll rates) |
| ------------------------------------------------------- | ----------------------- | ---------------------------- |
| 2 vCPU · 4 GB RAM · 10 GB disk                          | 250 – 500 devices       | Up to 1,000 devices          |
| 4 vCPU · 8 GB RAM · 10 GB disk                          | 500 – 1,000 devices     | Up to 2,000 devices          |
| Codec-heavy estates (many video-conferencing endpoints) | Around 60% of the above | Around 75% of the above      |

Capacity depends on poll rates, WAN latency to each site and the mix of adapters. Involve confirms sizing for your estate during onboarding.

## When to add another Collector

* A single host serves more than 500 devices.
* A remote site is more than 50 ms away and has dozens of devices.
* You want to isolate business units or environments from each other.

Packaging doesn't affect sizing: a container with 2 vCPU and 4 GB behaves the same as a VM with 2 vCPU and 4 GB.
