What is the supported speed and frame size on the cluster interconnect?

1 Gbps is insufficient for the high-bandwidth demands of a cluster interconnect, and 1500 MTU does not leverage the performance benefits of jumbo frames.

While 9000 MTU is correct for performance optimization, 1 Gbps does not meet the necessary speed requirements for modern cluster interconnects.

While 10 Gbps provides the required speed, using a 1500 MTU instead of 9000 MTU negates the performance benefits of jumbo frames for efficient cluster communication.

Modern cluster interconnects are designed to handle high-bandwidth internal communication between nodes, mandating at least 10 Gbps Ethernet to support cluster operations. Jumbo frames, with an MTU of 9000 bytes, are crucial for reducing CPU overhead and improving throughput of large data transfers within the cluster, which is common for internal synchronization and data movement.

Cluster interconnects have very specific technical requirements for network speed and MTU to ensure stability, performance, and proper functionality, making the statement that there are no specific requirements incorrect.
