Brocade® Web Tools, an intuitive and easy-to-use interface, enables IT organizations to monitor and manage single Brocade Fabric OS® (FOS)-based switches.
IT organizations responsible for maintaining business-critical mainframe infrastructures need the right tools, experience, and expertise to keep their enterprises running smoothly.
Brocade® ISL Trunking is an optional software product available for all Brocade 2, 4, and 8 Gbit/sec Fibre Channel switches, Brocade Fabric OS®-based directors, and the Brocade DCX™ Backbone.
Brocade® Fabric Watch is an optional Storage Area Network (SAN) health monitor for Brocade switches. Fabric Watch enables each switch to constantly watch its SAN fabric for potential faults—and automatically alert network managers to problems before they become costly failures.
Fibre Channel-based networking technology has revitalized the reliability and performance of server and storage environments—providing a robust infrastructure to meet the most demanding business requirements.
Based on Brocade® Frame Filtering technology and a unique performance counter engine, Brocade Advanced Performance Monitoring is a comprehensive tool for monitoring the performance of networked storage resources. This tool helps reduce total cost of ownership and over-provisioning while enabling SAN performance tuning, reporting of service level agreements, and greater administrator productivity.
The name Beiersdorf is associated with leading international brands across the skin and beauty care sector, such as NIVEA, Eucerin, Labello, La Prairie, Slek, and Hansaplast.
