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, or node failure.
We performed all tests as follows:
- With NIC failures to ensure a worst-case scenario for all sizing parameters.
- With drive failures in place in the A3000 cluster to ensure a worst-case scenario for all sizing parameters.
The following table provides bandwidth-sizing guidelines based on our test results.
