For high-performance iSCSI workloads, especially in a Nutanix environment using AHV nodes and a 10 GbE interface, enabling Jumbo Frames on both the Host and the Controller Virtual Machine (CVM) is recommended. Jumbo Frames allow for a larger payload per network packet, which reduces the overhead required to send large amounts of data. Enabling Jumbo Frames on both the host and the CVM ensures that both ends of the communication channel can handle larger packets, thereby optimizing throughput and reducing latency for high-performance workloads.

The proper network configuration to solve the described issue involves using tagged VLANs for the CVM (Controller Virtual Machine) and host, allowing these components to correctly interact with the customer's VLAN-configured network. For the IPMI (Intelligent Platform Management Interface), which is used for out-of-band management and does not require connectivity to multiple VLANs, setting it to access mode is appropriate. This configuration ensures that the IPMI only communicates over a single, untagged VLAN, effectively isolating its traffic from the production network.

When deploying Nutanix hardware, it is essential to ensure that all necessary components are included in the Bill of Materials (BOM). In this case, the BOM includes SFP+ modules but lacks the fiber cables needed for connectivity. The SFP+ modules indicate a requirement for fiber optic cables, and it's crucial for the consultant to ensure the client understands their responsibility to procure compatible cables. Nutanix typically does not provide fiber cables as these are considered network infrastructure components, which vary based on specific network requirements and setups.References:
