The test results are based on a model in which the constant-bandwidth safety and security video traffic remained unaffected during a single node maintenance cycle, disk rebuild, SP failure, or non-disruptive upgrade.
We used 10 Gigabit Ethernet (GbE) interfaces. We performed all tests with a per-camera bandwidth of 4 MB/s Mb/s, so a single SVR that handles 30 MB/s can support 60 such cameras.
We performed all tests with node or drive failures in place in the cluster (for example, with Isilon FlexProtect running) to ensure a worst-case scenario for all sizing parameters. Maximum per recorder bandwidth may vary based on the configuration of the SVR server used.
The following table provides bandwidth-sizing guidelines based on our test results.

This guide provides details on the total load that was tested in the Dell EMC Safety & Security Lab. However, the independent software vendor (ISV) should provide the actual server specification. The test results in this guide set a server bandwidth specification that is based on our lab environment, which can be used in the event the ISV does not provide these specifications.
