DFW operates transparently within the hypervisor kernel, ensuring efficient and scalable traffic inspection and enforcement.

Fault Domains in VMware vSAN are used to group ESXi hosts together to ensure data availability and protection against failures. By defining Fault Domains, administrators can designate which hosts share common failure domains, such as power supplies or network switches. In the event of a failure, vSAN ensures that data remains accessible by distributing replicas across different Fault Domains, enhancing resiliency and reducing the risk of data loss.

vSAN Automatic Rebalance is a feature that automatically redistributes data across vSAN disks to maintain balanced utilization and performance within the cluster. As storage demand increases or decreases, vSAN automatically adjusts the distribution of data to ensure optimal resource utilization and performance. This eliminates the need for manual intervention and enables seamless scalability of storage capacity in vSAN environments.

Incompatible firmware versions on ESXi hosts can cause vSAN disk groups to become “Degraded” due to compatibility issues with the underlying hardware. When vSAN disk groups are degraded, it indicates that one or more disks within the group are experiencing problems, such as connectivity issues or failure to respond. Updating firmware to a compatible version can resolve compatibility issues and restore the health of vSAN disk groups.
