1 XGIG PRODUCT FAMILY Protocol Analysis and Traffic Generation for SAS/SATA, Fibre Channel and Ethernet

2 PROTOCOL ANALYZERS AND TRAFFIC GENERATORS FOR SAS/SATA, FIBRE CHANNEL AND ETHERNET The Finisar Xgig family of distributed systems for monitoring, analysis, and testing contains multi-purpose systems designed to help the user meet challenges and accelerate development with today s high speed serial Storage Area Networks (SAN) and subsystems. Finisar Xgig systems are designed around the Fibre Channel, Gigabit Ethernet/iSCSI/FCIP and SAS/SATA protocols (see Figure 1). Xgig's views take the user quickly to the root of problems and issues. FINISAR'S XGIG PLATFORM The Xgig is a powerful Protocol Analyzer and Tester for Fibre Channel, Gigabit Ethernet and SAS/SATA links. It has advanced features such as cross triggering (internal and external) and expert analysis making it an ideal platform for solving challenges with today s high-speed serial buses. Figure 1: High Speed Serial Protocols supported The Xgig employs a chassis and blade hardware architecture. Various blades are available to support the Fibre Channel, Ethernet and SAS/SATA protocols. The blades have the unique ability to be multi-functional. They can be changed from a Protocol Analyzer to a Jammer to a BERT by simply toggling software switches. There is no need to change hardware. The Xgig system either can be placed directly in-line (in the case of SAS/SATA) on a link (see Figure 2) or can non-intrusively monitor the link, using Finisar s family of copper or optical TAPs. Figure 2: Typical Xgig Configuration In addition, multiple Xgig systems can be cascaded together to form a group providing support from two to sixty four time-synchronized analysis or test ports. The Xgig system operates with SAS/SATA, Fibre Channel, and Ethernet traffic simultaneously in either a cascade or non-cascade situation (see Figure 3). This feature is unique to Finisar analyzer and test products. The Xgig system is controlled by user applications that run on a Windows management PC. The PC and the Xgig system are connected through a GbE and LAN connection, enabling remote monitoring and analysis. Figure 3: Using a Cascaded Xgig System with a SAN

3 ❶ ❷ Figure 4: Xgig Trace Control In addition, the Xgig system is able to operate even when the connection to the user s software is severed. Example: A capture can be started, and then the management PC can be disconnected and later reconnected without any interruption to the Xgig system. ANALYSIS Xgig analysis system streamlines resolution of events that cause performance problems and enables users to design, implement, test and evaluate SANs and their components. The integrated suite of software available for analysis includes TraceControl, Performance Monitor, TraceView and Expert. TRACE CONTROL TraceControl is used to define the specific conditions under which the capture occurs. It initiates the capturing and stopping sequence and also provides a traffic library with pre-defined and user-defined templates ❶ for frames, ordered sets and errors (see Figure 4). TraceControl also allows users to define multi-level trigger events, including timeouts and missing events and specific ❷ conditions. As an example, TraceControl can be configured to wait for a specific network traffic condition to occur (such as a certain frame type) before beginning a capture, or start capturing immediately. TraceControl can change a blade function to an Analyzer, BERT, or Jammer and define the protocol for the blade. If the blade is licensed to support the Fibre Channel and Ethernet protocols and the Analyzer and Jammer functions, TraceControl can configure the blade (and individual ports) as a Fibre Channel Analyzer, Fibre Channel Jammer, Ethernet Analyzer or Ethernet Jammer. PERFORMANCE MONITOR When there is live traffic on any of the links being monitored, Performance Monitor collects and graphically reports performance metrics and data errors in real time. Users can view MB/s, Kframes/sec and physical layer errors from each direction of the link (see Figure 5).

4 PROTOCOL ANALYZERS AND TRAFFIC GENERATORS FOR SAS/SATA, FIBRE CHANNEL AND ETHERNET ❸ Figure 5: Xgig Performance Monitor Performance Monitor views provide quick snapshots of the current running state of the links being analyzed, as well as total statistics over time. Chart View displays performance metrics over time for every active, selected port. List View ❸ displays performance data in a tabular format. The units for these tables in each column are selectable via the tabs at the bottom of the List View table. Table views include data transferred in megabytes, data transferred in kiloframes, utilization percentage, frame statistics, frame errors, and physical errors. interpretation of the captured data for each event displayed in columns. You can add, delete, or move columns. Below the spreadsheet view is the Data Inspector pane ❺ that shows detailed interpretation of all the raw data of an event on the left side. You view single events from the spreadsheet display within the Data Inspector pane. To change events, select a new event in the spreadsheet display. The current transfer rate and the metered representation of the transfer rate are shown in Meter View. LED View indicates the current status of all ports and LED Summary View indicates the summary status of all ports. The number of ports that are in a particular state is indicated with the status type. Like TraceControl, you can set the clock rate for ports and the type of signal retiming directly from Performance Monitor. TRACE VIEW TraceView provides simultaneous display of Fibre Channel, Ethernet and/or SAS/SATA data traffic. The basic display in TraceView ❹ is a spreadsheet-like view with each trace event shown as a row and the Three different views are available for event data including a 8/10 bit data view and a protocol tree view. The right side ❻ of the Data Inspector shows the hexadecimal values for the event and their ASCII or EBCDIC representations. The hexadecimal area can be resized for a display of anywhere between 4 and 32 bytes of data per line. The traffic or trace histogram ❼ represents the entire trace from start of capture to end of capture. The trace can expand and collapse to look at a graphic display of a detailed portion of the trace. Meanwhile, bookmarks enable you to mark locations for reference and quick access.

5 ❹ ❺ ❻ ❼ Figure 7: Trace View Software The quick hide tool filters out frames or other event information that you want to remove from the display. Quick hide is primarily for hiding events based on the value of fields as you find them in the display. For example, you can easily hide all data from Port 3. EXPERT Expert provides a unique and robust set of debugging and analysis capabilities. It automatically sorts through millions of events to identify performance, upper layer protocol, logical and physical layer issues. Protocol violations, interoperability problems, performance issues and errant behaviors can be flagged and reported. Expert provides three views: the Topology View, the Error Log and the Graph View. The Topology View shows the network topology as derived from the trace data. The topology is built from advanced network detection and topology determination algorithms and shows any devices that are actively participating on the monitored links. The Error Log ❽ shows a list of Expert Errors, Warnings and Information Events that have been identified within a trace. When processing a trace, the Xgig Expert rebuilds protocol stacks and layers to identify erroneous and other undesirable behaviors within the network. The Graph View ❾ shows a highly configurable time-based graph representing activity for the trace. Activity can be tracked for individual devices or for aggregated devices. Data from multiple Analyzers can be overlaid onto the graph, allowing for simultaneous analysis.

6 ❽ 4 Gb/s Optical SFP ❾ 1 Gb/s Copper SFP Figure 8: Xgig Expert MULTI-FUNCTIONALITY 10 Gb/s XFP SAS/SATA SFP Jamming With the Xgig Jammer, network managers can manipulate traffic on a network to simulate errors in real time and to verify that the recovery process operates as expected. It is used in conjunction with one or more Xgig Analyzers to capture modified traffic and the system response to that traffic. The Jammer can trigger the Analyzer, and the Analyzer can arm the Jammer. The Xgig Jammer is transparent to the network, acting like an additional length of cable. Traffic passes through the Jammer until it detects a specific sequence of events. The Jammer makes a user-defined modification to a specified frame or ordered set, and then the module returns to pass-through mode. Bit Error Rate Test (BERTs) Physical-layer testing requires worst-case data loading and bit-by-bit data checking with results presented in an industry-accepted format. The Xgig BERT verifies data integrity by sending industrystandard worst-case data patterns through network devices. These data patterns are designed to stress the physical layer of the system, with patterns specifically developed to check frequency response, data dependencies, and network interface components. With bit-by-bit comparison, any difference between the transmitted and received data is detected, counted, and captured for additional analysis. Unique data patterns can be created to meet special test requirements.

7 The Xgig BERT is protocol-aware for Gigabit Ethernet and Fibre Channel. The unit recognizes data modifications allowed by devices on the link and does not report them as errors. It can also greatly reduce manufacturing test times for test hubs, host bus adapters, Fibre Channel RAIDs, and other active or passive devices by stressing all of the components in the data path. NETWISDOM The Xgig Analyzer can be used with Finisar s NetWisdom, a SAN performance-monitoring tool that helps ensure SAN health and uptime. When NetWisdom detects a problem on the SAN, the Xgig Fibre Channel Protocol Analyzer takes a trace and captures a sample of traffic on the link. Xgig s Expert software then reviews and analyzes the trace information and reports the problem. Please refer to the NetWisdom data sheet for additional information on this product.
