NCM-MCI: Nutanix Certified Master - Multicloud Infrastructure

Question

An administrator plans to deploy a Nutanix cluster to support a small number of high-performance VMs. The deployment has these considerations:

Individual VMs will probably generate network throughput of 90–100 Mbps.
Because of the VM configuration, a node is unlikely to host more than one or two of them at a time.
Individual VMs will communicate with only a few—one or two—remote hosts at a time.
Multicast will not be used in the environment.
The hosts are connected through two 1GbE network connections.

How should the administrator configure the network bonds to satisfy this requirement while keeping the switch configuration as simple as possible?

Explanation

The balance-slb bond mode provides active-active MAC-pinning load balancing across the two uplinks without requiring switch-side LACP configuration. Its multicast-traffic caveat does not apply when multicast is not used, while the two uplinks can be utilized by the VM NICs. Nutanix documents balance-slb as active-active MAC pinning and distinguishes it from balance-tcp, which requires LACP and link aggregation.
