This particular Enterprise Bundle consists of Fabric Watch, ISL Trunking and Advanced Performance Monitoring.
Brocade 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. Fabric Watch tracks a variety of SAN fabric elements, events, and counters. Monitoring fabric-wide events, ports, transceivers, and environmental parameters permits early fault detection and isolation as well as performance measurement. Unlike many systems monitors, Fabric Watch is easy to configure. Network administrators can select custom fabric elements and alert thresholds - or they can choose from a selection of preconfigured settings. In addition, it is easy to integrate Fabric Watch with enterprise systems management solutions. By implementing Fabric Watch, storage and network managers can rapidly improve SAN availability and performance without installing new software or system administration tools.
Brocade ISL Trunking is ideal for optimizing performance and simplifying the management of multi-switch SAN fabrics containing Brocade 1, 2, and 4 Gbit/sec switches and directors and the 8 Gbit/sec solutions. When two or more adjacent ISLs in a port group are used to connect two switches with trunking enabled, the switches automatically group the ISLs into a single logical ISL, or "trunk". The throughput of the resulting trunk can be anywhere from4 Gbit/sec to as much as 68 Gbit/sec.
Brocade Advanced Performance Monitoring is essential for optimizing fabric performance, maximizing resource utilization, and measuring end-to-end service levels in large Storage Area Networks (SANs). 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.
FABRIC WATCH FEATURES:
Constant monitoring for large, heterogeneous SAN fabrics
For a growing number of organizations, SAN fabrics are a mission-critical part of their systems architecture. These fabrics can include hundreds of elements, such as hosts, storage devices, switches, and Inter-Switch Links (ISLs). A flexible solution like Fabric Watch can optimize SAN value by tracking a wide spectrum of fabric events.
Automatic event notification
Fabric Watch lets administrators define how often to measure each switch and fabric element and specify notification thresholds. Whenever fabric elements exceed these thresholds, Fabric Watch automatically provides an event notification that can send a message to an e-mail address.
Rapid deployment and configuration
Fabric Watch is designed for rapid deployment, custom configuration, and immediate fabric monitoring. Network administrators can easily create and modify configuration files using a text editor, and then distribute configurations to all the switches in the SAN through Brocade Fabric OS configuration management utilities. Fabric Watch also comes with preconfigured profiles for rapid, "out-of-the-box" implementations.
ISL TRUNKING FEATURES:
Increased performance with ISL Trunking
ISL Trunking is designed to significantly reduce traffic congestion in storage networks. Up to eight ISLs can be combined into a single logical ISL with a total bandwidth of 68 Gbit/sec that can support any number of devices. To balance workload across all of the ISLs in the trunk, each incoming frame is sent across the first available physical ISL in the trunk. As a result, transient workload peaks are much less likely to impact the performance of other parts of the SAN fabric and bandwidth is not wasted by inefficient traffic routing. ISL Trunking can also help simplify fabric design, lower provisioning time, and limit the need for additional ISLs or switches.
Dynamic path selection for optimized performance
To further optimize network performance, Brocade 4 and 8 Gbit/sec switches and directors support optional Dynamic Path Selection (DPS). Available as a standard feature in Brocade Fabric OS (starting in Fabric OS 4.4), exchange-based DPS optimizes fabric-wide performance by automatically routing data to the most efficient available path in the fabric. DPS augments ISL Trunking to provide more effective load balancing in certain configurations, such as routing data between multiple trunk groups - or in Native Connectivity configurations with Brocade M-Enterprise OS (M-EOS) products. This approach provides "transmit" ISL Trunking from Fabric OS to M-EOS products while M-EOS products provide transmit trunking via Open Trunking, thereby enabling bidirectional trunking support. As a result, this combination of technologies provides the greatest design flexibility and the highest degree of load balancing.
Trunking over distance
Depending on the number of links and link speeds employed, trunks can operate at various distance/bandwidth combinations. For example, trunking can support distances of 345 kilometers for a 2 Gbit/sec, 5-link trunk providing over 10 Gbit/sec of trunk bandwidth, or 210 kilometers for a 4 Gbit/sec, 4-link trunk providing 17 Gbit/sec of trunk bandwidth.
The failure of a link in a route causes the network to reroute any traffic that was using that particular link - as long as an alternate path is available. Brocade Fabric Shortest Path First (FSPF) is a highly efficient routing algorithm that reroutes around failed links in less than a second.
ADVANCED PERFORMANCE MONITORING FEATURES:
END-to-end monitoring of switched fabric sans
Advanced Performance Monitoring enables administrators to monitor both "transmit" and "receive" traffic from the source device all the way to the destination device. Applications such as Web serving, databases, or email can be analyzed as complete systems with near-real-time performance information about the data traffic going between the servers and the storage devices. This end-to-end visibility into the fabric enables administrators to quickly identify bottlenecks and optimize fabric configuration resources.
ALPA- and filter-based monitoring
In loop SAN topologies, ALPA-based monitoring provides the ability to collect CRC error counts in Fiber Channel frames for each address. For direct-attach SAN topologies, filter-based monitoring provides CRC error counts for each implemented filter.
Frame filtering on the first 64 bytes
Advanced Performance Monitoring also provides the unique ability to filter any of the first 64 bytes in a Fiber Channel frame. The counter is incremented each time a frame is filtered through the corresponding port. Predefined port filter statistics include SCSI read/write, read, or write commands; CRC error statistics; and IP versus SCSI traffic comparisons. These statistics give administrators the critical information they need to monitor the SAN fabric.
A counter engine to compile raw data
The counter engine works with the Brocade Frame Filtering capability to collect and compile raw data from the filters into meaningful information. In addition to the standard filters (read, write, read/write, and frame count), administrators can customize filters to qualify frames for statistics gathering.
An improved GUI
Advanced Performance Monitoring makes powerful underlying capabilities simple and easy to use. An enhanced graphical user interface launched from Brocade WEB TOOLS gives administrators "at-a-glance" information needed to anticipate and resolve problems. Administrators can display up to eight performance graphs on a single user-defined management "canvas". Different canvasses can address different users, scenarios, or host applications. Saved canvas configurations enable administrators to change views quickly and easily.
Enhanced reporting capabilities
A rich set of predefined graphs are provided for the most common tasks. In addition, administrators can customize predefined performance graphs on virtually any parameter, and add them to canvas configurations. They can also generate printouts or reports in minutes by using previously saved or customized layouts, along with easy-to-use drag-and-drop screens.
Superior investment protectionProduct Highlights
Advanced Performance Monitoring can be used on any Brocade 2 Gbit/sec switch or director. The performance monitoring features can be used as long as the data path of the target flows through a switch that has Frame Filtering capabilities. Existing Brocade switches do not need to be replaced or modified.
