The SierraNet M328 is the most cost effective, advanced and fully integrated Ethernet and Fibre Channel data capture, protocol verification, and frame/data modification systems available for developers and protocol test engineers. The M328 protocol analysis systems provide engineers with 100% recording of all Fibre Channel and Ethernet related traffic at full line rates on all ports while maintaining the link integrity through the digital probe technology.

The SierraNet M328 hardware platform and Net Protocol Suite™ user interface provides the highest level of performance and flexibility available in the market. SierraNet offers developers, test and support engineers with a compact, extremely flexible, multi-function protocol analyzer and traffic impairment platform.

The SierraNet M328 employs Teledyne LeCroy’s leading FlexPort™ technology providing ultimate flexibility in analysis of traditional or converged Ethernet and Fibre Channel products in a single platform and the flexibility to add protocol specific features, functionality, and speed support at the time of purchase or later by simply adding optional license keys.  

Each SierraNet FlexPort pair can probe both Ethernet – up to 25GbE – and Fibre Channel – up to 32GFC – links over DAC, AOC or optical transceiver and cabling and eliminates the need for separate “single function” blades, pods, or adapters found in some competitive products.  The pairs may be aggregated to support higher density links, 50GbE (25GbE x 2 links) up to 100Gbps Ethernet (25GbE x 4 links)

In addition to FlexPort technology, the SierraNet M328’s sophisticated analysis software, the Net Protocol Suite™, provides unmatched flexibility with customized data displays that easily and quickly navigate users to specific events of interest.  Decoding in the Net Protocol Suite’s multiple trace views provide superior visibility for troubleshooting low level to application layer issues, decoding traffic per the supported specifications and their associated encoding schemes, and the zero-time search and filter capabilities easily find Ethernet and Fibre Channel events in a contextual and intuitive way.  In a multi-protocol environment, Teledyne LeCroy’s CrossSync™ can synchronize and correlate traces with our other leading protocol analysis tools, such as the PCI Express Gen3 and Gen4 Summit analyzers, to understand how traffic, stimulus, and/or errors propagate across bridges or adapters.

The SierraNet M328 platform is Compact, Portable, and Light Weight. The SierraNet is currently the Smallest (1U) and lightest (9.5lbs) Fibre Channel and Ethernet protocol analyzer and traffic modification platform in the market, saving valuable real estate and rack space in customer labs and is the best portable solution for engineers on the move.  SierraNet provides users the lowest cost of ownership per engineer, and the lack of maintenance or support fees for subsequent years of operation means strained budgets are not tapped just to keep up with evolving specifications and advancements.

The SierraNet M328 offers the fastest and most convenient access to the data that engineers need with either a USB3.0 or GE interface.  As USB is Plug and Play, this is particularly useful when capturing large amounts of data is necessary, but a quick connection to the analyzer is required, such as at a customer site.  In addition to the performance and ease-of-use of the USB3.0 interface, a Gigabit Ethernet Host Interface is also standard on the SierraNet platforms, and the IP Address set-up menus on the front panel eliminate the time and complexity required to configure an analyzer via a null-modem cable and hyper-terminal interface used on competitive products.

The SierraNet M328 also offers the best Time-Stamp Resolution in the market. The SierraNet family has been enhanced with a 1ns time-stamp resolution/accuracy, setting a new industry standard for trace analysis and for timing measurements required for testing high performance SAN products, particularly where latency is a key metric of success.

Additionally, the SierraNet family’s Advanced State Machines are easy to use and help Engineers Trigger, Filter, and Inject errors with surgical precision with up to 4 sequencers and up to 24 states per sequencer to concisely target areas of interest and save precious time. When the user can not accurately define the conditions associated with a problem and needs to capture a broad swath of traffic to identify a cause of an issue, the SierraNet will dynamically assign the largest and most flexible recording memory in the industry to one port or spread the memory use across all eight ports based on the traffic profile.

The Teledyne LeCroy InFusion™ (Jammer) Error Injector and Traffic Modifier tool allows users to verify real-world fault handling for both Ethernet network and Fibre Channel fabric systems.  InFusion is only available for SierraNet platforms enabled with Digital Retimed circuitry and sits unobtrusively in the data path on a live system to programmatically alter or corrupt traffic. InFusion is the ideal tool for stress-testing systems using actual workloads and devices.

SierraNet InFusion supports Ethernet link speeds from 10GbE up to 100GbE and Fibre Channel links up to 32 Gbps, depending on the capabilities of the licensed SierraNet platform. InFusion monitors traffic from both directions in real-time and through the use of customer defined parameters, replaces or modifies any bit, ordered-set, checksum or other parameters with those specified for the test case.

InFusion can change traffic when it detects a specific sequence or reaches a designated time interval, yet it requires no complicated scripts, programming, or simulation tools. InFusion can monitor traffic in both directions and act on events occurring in either direction of the communications link. InFusion can even modify bi-directional traffic within a given test scenario, either from the Originator or from the Responder. InFusion is specifically designed to verify recovery characteristics within a subsystem. An easy, user friendly menu interface with icons and hyperlinks allows you to create specific test Scenarios in just minutes.

Once an InFusion session starts, the system automatically handles protocol handshaking between devices. InFusion transmits a faithful copy of the original data stream down to the CRC value which, if needed, it recalculates. InFusion allows test engineers to systematically verify error recovery in ways not possible with other test platforms.

• Error Injection: Injects CRC, disparity, PCS encoding (8b/10b, 64/66b, etc) framing, and coding errors.
• Break Link Recovery: Programmatically breaks the connection to test link recovery.
• Value Replacement: Monitors the link for specific values, patterns, or ordered-sets (as low as bit level) and replace with user-defined values. You can replace values on every occurrence, after a specified number of occurrences, or after a specified time interval.
• Packet Drop: Removes individual ordered-sets or frames from the stream to verify retry behavior.
• Packet Delay: Capture and individual frame and re-inset into the data stream to verify out-of-order reassembly.
• Ordered-set Manipulation: Replaces handshaking and flow control ordered-sets to help validate robustness of a design.
• Traffic Monitoring: Operates as a traffic monitor, collecting statistical data on user-specified parameters. In this mode, data passes unchanged in both directions.
• Menu-Driven Interface: Allows easy set-up of test Scenarios.

With respect to traffic modification, in the Link Layer you can modify ordered-sets, CRC, scrambled data, and connection Events. You cannot modify clock skew management and signal integrity. InFusion consists of a hardware device that connects to the line under test and a Windows-based software application used to create and download test scripts to the device. You also can use the software application to configure and control the device across an Ethernet or USB link. InFusion test scripts are called Scenarios. Scenarios determine how the hardware device monitors and modifies line traffic. In order to create and download Scenarios the Teledyne LeCroy Net Protocol Suite application must be used. For the InFusion connections, the device is connected between the PHYs of the originator and responder.
