When addressing high cluster IOPS and Cluster Controller Latency where networking is suspected to be the issue, it is essential to check the network configuration settings that can directly impact data transfer and latency. The correct answer is to adjust the "Number of NICs connected" and "frame size." Increasing the number of Network Interface Cards (NICs) connected can improve the network throughput and distribute the load more evenly. Adjusting the frame size, particularly setting larger frames (Jumbo Frames), can reduce overhead and improve network efficiency by allowing more data to be transmitted with fewer packets.

For a newly deployed Nutanix system where the customer has specified VLAN 10 for management traffic, the consultant should recommend using VLAN 10 for both CVM and AHV host traffic. This VLAN designation ensures that all management, monitoring, and internal cluster communication are on a dedicated network, separate from production VM traffic (VLAN 20) and backup/replication traffic (VLAN 30), thereby enhancing network security and performance.References:

* Node-Specific Password: Each Nutanix NX hardware node now ships with a unique default IPMI password for the ADMIN user.expand_more This password is the node's serial number (using capital letters).expand_more
* Finding the Serial Number: You can locate the node's serial number either on a physical sticker or by running the ipmitool fru print command on the node.
