In the scenario where SQL queries are running slower post-migration, creating multiple TempDB data files is a recognized best practice for optimizing SQL Server performance, especially when dealing with high transaction rates or complex queries. This approach helps in distributing the I/O load across multiple files and drives, reducing the contention and wait times associated with TempDB, which is a common bottleneck in SQL Server environments. Enabling autogrowth ensures that these files can dynamically grow as needed, which helps in handling unexpected increases in database activity without manual intervention.References:

According to Nutanix best practices for ESXi clusters, using a vSphere Standard Switch with "Route based on originating port ID" is recommended for load balancing. This method ensures that the same virtual port ID within a vSwitch uses the same uplink from the vSwitch. This load balancing policy provides an even distribution of traffic and redundancy by utilizing both NICs effectively without requiring any specific physical switch configurations, such as EtherChannel or LACP.References: The Nutanix Bible, NCS-Core 6.8 course content, and VMware's documentation on vSphere Standard Switch load balancing methods.

If a VM deployed on the storage network cannot access a SMB standard share, the likely issue is that:
* Clients on the same subnet as the storage network cannot access the shares: This scenario typically occurs due to network segmentation policies or firewall rules that restrict access to the storage network from clients within the same subnet, intended to segregate traffic types for security and performance reasons.

The issue indicated is that the VMs, specifically the CVMs (Controller VMs), do not restart on the remaining nodes after a network cable is removed, demonstrating a failure of HA (High Availability). The setting that should be verified is "Host Monitoring" within the ESXi HA/DRS settings. This setting enables the host to monitor the state of other hosts in the cluster and take necessary actions like VM restarts on other hosts in the event of failures. If it's disabled, the cluster wouldn't automatically manage the failover of VMs upon host disconnection.

In a typical Nutanix deployment using a flat switch, the Foundation VM, the CVM, and the Hypervisor should all be on the same subnet to facilitate seamless communication and management operations during the initial setup and operation. The IPMI, being a management interface, can be on a different subnet as it serves a different purpose primarily for remote management at the hardware level and does not need to be on the same subnet as the other components for cluster functionality.References:
