Use an active-active array for Fibre Channel storage-based VMFS datastores An active-active array provides redundancy and load balancing by allowing multiple paths to be active at the same time, ensuring better performance and fault tolerance. This supports the requirement for redundancy and no single point of failure by ensuring that storage traffic can be distributed across multiple paths to different storage controllers.
Configure a minimum of two paths to every LUN or datastore
Having multiple paths to every LUN or datastore is essential for ensuring redundancy in the storage path. In case one path fails, the system can continue to function by using the other path, meeting the requirement for tolerance to at least one failure.
Configure a minimum of four paths to every LUN or datastore
Configuring four paths further increases redundancy, ensuring that the storage system can tolerate multiple path failures while still maintaining access to the LUN or datastore. This improves load balancing and provides greater fault tolerance.
