Fabric Vision was introduced with IBM Network Advisor 12.1.x and FOS V 7.2.x. The Fabric Vision license includes support for Flow Vision, Monitoring Alerting Policy Suite (MAPS), Clear Link Diagnostic Port, Fabric Watch, and Advanced Performance Monitoring. Switches with Fabric Watch (FW) and Advanced Performance Monitoring (APM) licenses automatically get FOS V 7.2.x Fabric Vision license features simply by upgrading to FOS 7.2.x. Switches with only FW or APM can upgrade to Fabric Vision by purchasing other licenses.
IT organizations with large, complex, or highly virtualized data center environments often require advanced tools to help them more effectively monitor and manage their storage infrastructure. Developed specifically with these IT organizations in mind, Fabric Vision technology also includes several breakthrough diagnostic, monitoring, and management capabilities that dramatically simplify day-to-day SAN administration and provide unprecedented visibility across the storage network.
Fabric Vision is an extension of b-type Gen 5 Fibre Channel and introduces a breakthrough hardware and software solution that maximizes uptime, simplifies SAN management, and provides unprecedented visibility and insight across the storage network. Offering innovative diagnostic, monitoring, and management capabilities, Fabric Vision technology helps administrators avoid problems, maximize application performance, and reduce operational costs.
The following advanced technologies and capabilities are available with the optional Fabric Vision technology license:
ClearLink Diagnostics, a patent-pending technology, leverages the unique Brocade Diagnostic Port (D_Port) mode to ensure optical and signal integrity for Gen 5 Fibre Channel optics and cables, simplifying deployment and support of high performance fabrics. By pro-actively verifying the integrity of critical transceivers, organizations can quickly address any physical layer issues without the need for special optical testers.
Bottleneck Detection identifies and alerts administrators to device or ISL congestion as well as abnormal levels of latency in the fabric. When applied to F_Ports, Bottleneck Detection can continuously monitor for medium or high levels of latency on a device port and provide notification on the nature and duration of the latency. Bottleneck Detection can also serve as a confirmation to host information when storage latencies are suspected as the cause of poor host performance. The reverse (eliminating the storage as the source of poor performance) is also true. When applied to E_Ports, Bottleneck Detection can alert administrators when it detects high levels of latency on an ISL, often the result of congestion or latency from elsewhere in the fabric, but also a condition that can occur as a result of device latencies from multiple flows.
Flow Vision enables administrators to identify, monitor, and analyze specific application and data flows in order to maximize performance, avoid congestion, and optimize resources.
Flow Vision includes:
Flow Monitor: Provides comprehensive visibility into flows in the fabric, including the ability to automatically learn (discover) flows and non-disruptively monitor flow performance. Users can monitor all flows from a specific host to multiple targets/LUNs or from multiple hosts to a specific target/LUN; monitor all flows across a specific ISL; or perform LUN-level monitoring of specific frame types to identify resource contention or congestion that is impacting application performance.
Flow Monitor provides the following capabilities:
Flow Mirror: Provides the ability to non-disruptively create copies of specific application and data flows or frame types that can be captured for deeper analysis. Flow Mirror is used for in-depth analysis of flows of interest or specific frame types, such as analysis of SCSI Reservation frames, ABTS frames, or flows going to a bottlenecked device.
Flow Generator: Provides a built-in test traffic generator for pre-testing and validating the SAN infrastructure, including internal connections within a switch, for robustness before deploying new switches, blades, servers, storage, or applications. Flow Generator allows users to:
Monitoring Alerting Policy Suite
Monitoring Alerting Policy Suite (MAPS) provides a new, easy-to-use solution for policy-based threshold monitoring and alerting. MAPS proactively monitors the health and performance of the SAN infrastructure to ensure application uptime and availability. By leveraging pre-built rule-/policy-based templates, MAPS simplifies threshold configuration, monitoring, and alerting.
Organizations can configure the entire fabric (or multiple fabrics) at one time using common rules and policies, or customize policies for specific ports or switch elements—all through a single dialog. The integrated dashboard displays an overall switch health report, along with details on out-of-policy conditions, to help administrators quickly pinpoint potential issues and easily identify trends and other behaviors occurring on a switch or fabric.
MAPS offers the following:
Policy-based monitoring, including:
The CLI dashboard offers the following:
Bottleneck detection integration with MAPS dashboard:
Proactive flow monitoring using MAPS:
Automated migration of Fabric Watch configurations to MAPS:
