Advanced Performance Monitoring allows for end-to-end performance monitoring of traffic between a server and a storage device, assessing resource utilization on a fabric-wide basis. This enabling technology provides the ability to monitor and watch specific fabric metrics from a SID (Source ID) to a DID (Destination ID), creating a method to be able to fine-tune and scale your fabric more efficiently. Performance Monitoring also allows the ability to have an early warning detection of hot spots within the fabric providing a powerful tool for maintaining overall balanced performance. This results in improved performance tuning that maximizes fabric resource optimization and simplifies SAN capacity planning.
