4.25, and 8.5 Gb/s Fibre Channel

Cascading of multiple blade chassis allows high density time synchronous domains. Modular blade technology allows quick reconfiguration of chassis.




The Xgig 8.5 Gb/s FC analyzer is the industry’s first 8.5 Gb/s Fibre Channel analyzer. Expanding upon the Xgig FC current analyzer’s capabilities, it is a critical tool for engineers developing and troubleshooting products and systems that involve the FC protocol and ULPs such as iSCSI, FCP, FICON and FCIP. Key features on hardware include:

Industry’s most powerful trace capture: 100% capturing at any line rate up to the maximum data rate of 8.5 Gb/s backed by the largest trace buffer in the industry with 2 GB per SFP port.

Backwards Compatibility: the new 8.5 Gb/s FC mutli-function blade has the same form factor as the previous 4.25 Gb/s FC blade and captures/analyzes 1.065, 2.125, and 4.25 Gb/s FC traffic as well.

Scrambling: Support for scrambling in hardware for 1.065, 2.125, 4.25 and 8.5 Gb/s data rates. To simplify comparisons, scrambling can be easily turned on or off with a single click.

SFP Support: Available in 2- and 4- SFP port blades, the 8G FC blade is also SFP+ plug-in ready. SPF+ is the MSA form factor for 8.5 Gb/s FC transceivers.

Multiple Data Tapping Methods: Two data tapping methods provide options of nominal signal quality impact and data stream clean-up.

Multi-functional: Each blade can be served as a protocol analyzer, Jammer, BERT, and other traffic generation products through simple software configuration, without changing hardware.

Cascadable: Multiple Xgig systems can be cascaded together to group up to 64 time-synchronized ports for comprehensive system analysis and testing.

Client software features include:

Internal and external cross triggering Arm-sharing across all ports in a link Powerful trace filtering and searching

Maximum number of time-synchronized channels Industry’s highest time stamp resolution

Tx/Rx optical power reading

Support for the most recent updates on the 8G FC standard from theT10 committee, such as ARB(ff ) decode and Expert supports.


The Xgig analysis system streamlines resolution of events that cause performance impairments and enables users to design, implement, test, and evaluate FC components and subsystems. This integrated suite of software includes TraceControl, Performance Monitor, TraceView, and Expert.


Comprehensive traffic library

with pre-defined and user-defined FC templates for frames, ordered sets, and errors (see Figure 1) determines the specific conditions and sequences under which trace capture occurs.

Choice of signal regeneration method

determines impact on signal quality.

Multi-level trigger eventsenable users either to start capturing immediately or to wait for a specific network traffic condition to occur before beginning a capture based on operating conditions including timeouts, missing events, and specific memory conditions.

Arm-sharingcovers all ports within a specific link and chassis. Arm and rollback signals are distributed between configurable ports within a link, and all ports in a domain share the arm state. Up to eight such links can be defined within a chassis.


Scramblingfor 1.065, 2.125, 4.25 and 8.5 Gb/s traffic can also be turned on or off within the link speed control window. The default setting for 1.065, 2.125, and 4.25 Gb/s FC traffic is scrambling off; the default for 8.5 Gb/s traffic is scrambling on.

TraceControl can show the live optical power reading of the SFP TX/RX inside the blade, as well as the SFP make and model number.

Domains (sets of port pairs) can be defined within a single chassis (intra-chassis) or across multiple, concatenated chassis (inter-chassis). 32 domains can be simultaneously

capturing on a 64 port sync group. Multiple domains provide great flexibility in using Xgig ports, allowing for efficient support of multiple Xgig users.



Performance Monitor collects and graphically reports performance metrics and data errors in real time whenever there is live FC traffic over any monitored link. Users can view MB/s, Kframes/sec, utilization, frame errors, and physical layer errors from each direction of the link.

Performance Monitor also provides quick snapshots of the current running state of analyzed links, as well as total statistics over time:

LED View

: shows the current status of all ports. LED Summary View

: shows the summary status of all ports.

Meter View

: indicates the current transfer rate and the metered representation of transfers.

Chart View

: shows historical port information over time.

List View : displays a set of Table Views with monitor data for each port.

Just like in TraceControl, the clock rate for ports and the type of signal retiming can be set directly from Performance Monitor.

resembles a spreadsheet, where each trace event is shown as a row and the interpretation of the captured data for each event is displayed in columns. Unlike the competition’s viewing software, TraceView’s spreadsheet is 100% configurable, allowing users to customize views by adding or removing any protocol field as a TraceView column.

Data Inspector, located below the spreadsheet display, offers a detailed interpretation of the raw data of events on the left side. A new event can be selected in the spreadsheet display to change the event displayed in the Data Inspector pane. The right side of the Data Inspector pane shows the hexadecimal values for the event and their ASCII or EBCDIC representations.

data view and a protocol tree view


Dword Viewallows the viewing of trace data in a Double Word format. This view is especially useful for Dword-oriented protocols such as SAS/SATA.

Built-in Histogram Capabilities

represent the entire trace from start to end. The trace can be expanded or collapsed to focus upon a detailed portion of the trace. Bookmarks allow locations to be marked for reference and quick access. Patented Search and Filter Capabilities(see Figure 4), viewed by many as the best available in the industry, enables users to search and filter any field value or string in the entire capture with as few as 2 to 5 clicks.

Expert (see Figure 5) provides a unique and robust set of debugging and analysis capabilities, including automatic sorting through millions of events to identify performance, upper layer protocol, and logical and physical layer issues. FC protocol violations, interoperability problems, performance issues, and errant behaviors are flagged and reported. Finisar’s Expert Analysis supports more than 1800 metrics and 1200 Experts across the protocols such as FC-2/4, FCP, SCSI, iSCSI, FCIP, iFCP, SAS/SATA, SAS-SSP, GigE, IP, IPv6, and TCP. Expert provides four views.

Topology View shows the network topology as derived from the trace data, including the location of initiators, targets, and expanders. Topology view is built from advanced network-detection and topology determination algorithms and shows all devices that are actively participating on each link. Error Log Viewshows errors, warnings, and information events that have been identified within the FC trace. When processing a trace, Finisar’s Expert Analysis tool rebuilds protocol stacks and layers to identify erroneous and other undesirable behaviors within the network.

Graph View shows a highly configurable time-based graph representing activity for the trace. Activity can be tracked for individual or aggregated devices. Data from multiple analyz-ers can be overlaid onto the graph, allowing for simultaneous analysis. Example: A quick view of the graph reveals that the expander is not properly performing load balancing on the links and that there is little or no activity on links 0 and 1. Report ViewA traffic report can be generated from Expert Analysis, which contains the statistics information such as line rate, bus utilization, credit flow, exchange statistics, loop characteristics, arbitration, and SCSI statistics.


As an alternative control program to TraceControl, Frunner allows users to control Xgig hardware through scripts such is often needed for automated testing. Frunner can be called from C/C++, Perl, and Python environments, and allows users to design any combination of customized triggers and controls. In conjunction with Frunner, the Tgptotxtscripting tool formats captured data as text output for easy parsing.
