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 per node
- Do not exceed VM designs above 1200 Mbps per server
The following tables provide bandwidth-sizing guidelines based on our test results.
