More

Teledyne LeCroy has been an industry leader in storage protocol analysis. The storage SSD/Drive technology is now moving towards a PCI Express host based interface. Teledyne LeCroy supports the following:



-NVM Express

-SCSI Express

-SATA Express

Teledyne LeCroy offers five PCI Express protocol analyzer platforms (Summit™ T3-16, Summit T3-8, Summit T34, Summit T28, and Summit T24). The Summit T3-16 Analyzer is Teledyne LeCroy's fifth generation architecture and highest performance platform. It provides full bidirectional support of x16, x8, x4, x2, and x1 at data rates up to 8 GT/s. With 8 GB of trace memory, it offers enough capacity for analyzing and recording extensive PCI Express data streams. Supporting lane widths up to x8 at 8 GT/s, the Summit T3-8 offers the same powerful features and as an option allows for two T3-8 systems to be connected together to achieve a full x16 lanes at 8 GT/s. Ideal for embedded systems monitoring and analysis is the Summit T28, smaller and a more cost effective PCI Express protocol analyzer for x8 lanes at 5GT/s. While all of the Summit analyzers support PCIe storage protocols like NVM Express, SATA Express and SCSI Express, the Summit T34 is addresses PCIe storage analysis with a small, portable form factor, x4 lane width and a deep recording buffer of 32 GB of memory. For portability and ease-of-use the Summit T24 protocol analyzer offers analysis support for x1-x4 lanes at 2.5/5GT/s. The Summit T24 is Teledyne LeCroy's most optimized and low cost analyzer for analysis of PCIe 2.0 add-in-boards.

All Summit analyzer platforms use the PCI Express iPASS connector for probing. Teledyne LeCroy features the largest selection of PCIe based interposers and probing solutions. Teledyne LeCroy's PCI Express Protocol Analyzer solutions employ non-intrusive and transparent probing technologies thereby allowing fully unaltered data pass-through. In addition, it leverages the intuitive and powerful Teledyne LeCroy’s Trace expert software system, embedding a deep understanding of the PCI Express protocol hierarchy and intricacies and presents this knowledge to the user in a colorful, intuitive and easy to use graphical display, allowing users to quickly capture and validate PCI Express product designs. These analyzers enable IP, semiconductor, switch, software and system developers as well as add-on card vendors to quickly identify protocol violations and ultimately reduce development and debugging time.

Developers can use Teledyne LeCroy's PCI Express Protocol solutions to easily capture and decode PCI Express Transaction Layer Packets (TLPs), Data Link Layer Packets (DLLPs), and low-level link traffic, including Training Sequences and Skip Ordered-sets. Some of the errors detected include: 8b/10b errors, such as invalid symbols and incorrect running disparity; CRC errors; idle data errors; and EDB (End-of-Packet Bad) errors. They also provide a detailed display of split transactions, correlating requests transmitted from one PCI Express endpoint with completions received from the endpoint at the opposite end of the link.

Teledyne LeCroy is well known for its technical leadership. Customers have come to depend on Teledyne LeCroy supporting protocols while they are early in development when these tools are essential.

Exercisers

The PCI Express exercisers can generate PCI Express transactions, observe behavior, and perform both stress testing and compliance testing. The Summit Z3-16 supports the new Specification 3.0 ("Gen3") data rates of 8 GT/s across up to 16 lanes. The Summit Z3-16 Exerciser supports up to x8 lane widths at data rates of 2.5 GT/s. As complete solutions, both the Summit T3-16 and Summit Z3-16, or PETracer/Trainer™ systems give you the unique ability to record (capture) live traffic, modify the traffic, and then playback the exact data stream, or "script," using the exerciser.

Protocol Test Card

Teledyne LeCroy offers an integrated and automated compliance testing system, including Protocol Test Cards, approved by the PCI-SIG® as a standard tool for compliance testing for developers working with both the PCIe 2.0 and 3.0 specifications. In addition, the Summit Z3-16 exerciser is the only approved tool to run the UNH-IOLs NVM Express Conformance Tests. These tests are required for the NVM Express Integrators test.

 

Teledyne LeCroy provides NVM Express, SATA Express and SCSI Express protocol decoding, analysis and test equipment to SSD storage companies worldwide. It works closely with the following organizations providing equipment to its members and conformance programs.

NVM Express, Inc. consists of more than 60 companies from across the industry. NVM Express was formed as an industry association to define a new storage interface protocol, NVM Express, to enable the full performance potential provided by Non-Volatile Memory based storage technology, such as PCI Express Solid State Drives in a standards based approach that enables broad ecosystem adoption and interoperability. www.nvmexpress.org/

The UNH-IOL offers conformance and interop testing for NVMe hosts and devices, helping products to qualify for the NVMe Integrators List. UNH-IOL also uses their NVMe interop test bed to enable heterogeneous testing across various OS, drivers, and hardware platofrms to prove the viability and robustness of NVMe. www.iol.unh.edu/testing/storage/nvme

Test services include:

  • Conformance testing using the IOL INTERACT PC Edition software
  • Conformance testing using the IOL INTERACT Teledyne-LeCroy Edition software
  • Interoperability testing using VDbench software

 

The SATA-IO provides the industry with guidance and support for implementing the SATA specification. www.sata-io.org/

The SCSI Trade Association provides the industry with guidance and support for implementing the SCSI specification. www.scsita.org/
