The test results are based on a model in which the constant-bandwidth safety and security video traffic remained unaffected during select storage failure scenarios, such as disk rebuild, node failures, and failing network paths.
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 cluster (for example, with Isilon FlexProtect running) to ensure a worst-case scenario for all sizing parameters.
- With 10 GbE interfaces with no more than two SMB connections per interface. A 10 GbE interface can accommodate up to four Recorder connections at the maximum XProtect -supported values.
- With a per-camera bandwidth of 4 Mb/s.

The following table provides bandwidth-sizing guidelines based on our test results.
Cluster | version | OneFS version | per node | Bandwidth MB/s (Mb/s) | Drive size | |
Per VM | Per PowerScale node | |||||
A2000 | 5.8 | 8.1.2 | 1 | 37.5 (300) | 37.5 (300) | 10 TB |

Dell VxRail E560
The test results are based on a model in which the constant-bandwidth safety and security video traffic remained unaffected during select storage failure scenarios, such as disk rebuild, node failures, and failing network paths.
Dell Technologies recommends:
- Keep some RAM (16GB) for the virtualization OS
- Do not run more than 6 VMs total
- Do not exceed VM designs above 1200 Mbps per server
