pending IOs, and IOPS metrics for a flow from a specific host to a target or volume running SCSI or NVMe over Fibre Channel traffic. With VM Insight, administrators can monitor network throughput and IO statistics for each VM. 

Flow Learning: Enables administrators to non-disruptively discover all flows that go to or come  from a specific host port or a storage port, or traverse ISLs/IFLs or FCIP tunnels, to monitor fabric-wide application performance. In addition, administrators can discover top and bottom bandwidth-consuming devices and manage capacity planning. 

Flow Generator: Provides a built-in traffic generator for pretesting and validating the data center  infrastructure for robustness, including route verification and integrity of optics, cables, ports, back-end connections, and ISLs, before deploying applications. 

Flow Mirroring: Enables administrators to non-disruptively create copies of specific application  and data flows or frame types that can be captured for in-depth analysis. 

Forward Error Correction (FEC): Enables recovery from bit errors in a data stream, enhancing  transmission reliability and performance. FEC is mandatory in Gen 6 links with more robust error recovery to support 32 Gbps performance. 

Credit Loss Recovery : Automatically detects and recovers buffer credit loss at the Virtual Channel  (VC) level, providing protection against performance degradation and enhancing application availability. 

## IBM Network Advisor 

IBM Network Advisor simplifies b-type Gen 6 Fibre Channel management and helps organizations proactively diagnose and resolve issues to maximize uptime, increase operational efficiency, and reduce costs. The wizard-driven interface dramatically reduces deployment and configuration times by allowing fabrics, switches, and ports to be managed as groups. Customizable dashboards graphically display performance and health indicators out of the box, including all data captured using Fabric Vision technology. To accelerate troubleshooting, administrators can use dashboard playback to quickly review past events and identify problems in the fabric. Dashboards and reports can also be configured to show only the most relevant data, enabling administrators to more efficiently prioritize their actions and maintain network performance. For more details about IBM Network Advisor capabilities, review the information in the data sheet and IBM Network Advisor Redbooks product guide.
