Teledyne LeCroy Announces New NVM Express Protocol Analyzer and Exerciser for NVM Express Management Interface

SANTA CLARA, CA --- Teledyne LeCroy announces the availability of their new SMBus protocol-enabled Summit T34 Protocol Analyzer and Summit Z3-16 Exerciser/Test Platform targeted at testing and monitoring SSD devices and systems using the NVM Express (NVMe) protocol. NVMe is associated with high performance storage technology and is now enabling network monitoring in storage systems using PCIe and SMBus signaling which are important components of the new NVM Express Management Interface (NVMe-MI) protocol. The Summit T34 protocol analyzer has been enhanced to support SMBus protocol decoding that is integrated into the current NVMe and PCIe protocol traffic trace display. The protocol exerciser/test platform also has been enhanced to generate SMBus protocol traffic which is useful for testing the NVMe-MI protocol in addition to the standard PCIe, NVMe and SATA Express traffic generation already in use by the storage industry.

A Datacenter is made up of a multitude of servers each with hundreds of SSDs. Failures happen from time-to-time causing potential data loss. To avoid this problem, BMC (Baseboard Management Controller) systems monitor storage devices and determine if there is a drop in performance or change in operating conditions. Pre-emptive action allows problem units to be identified and replaced maintaining high quality data access. The NVMe-MI protocol enables NVMe solid-state drives to be managed by the BMC over either SMBus (out-of-band) or PCI Express (in-band). The Summit T34 and Summit Z3-16 are an important part of system development to verify that the solution is working according to the NVMe-MI specification.

Traffic between the Host (Root Complex) and the DUT (Device Under Test) will be captured by a new class of interposers that have been developed to support both PCIe and SMBus channels. These new interposers include the PCIe External Cable 3.0 Interposer, standard interposers with the CEM connector and other specialized form factors coming soon. The sideband signaling PERST#, WAKE#, and similar functionality can be monitored by the Summit T34 through the interposer, where protocol issues and performance metrics can be analyzed and debugged. RefCLK# signals external to the cable are available on the PCIe External Cable 3.0 interposer for use with the protocol analyzer.

In 2010, Teledyne LeCroy was the first company to introduce a PCI Express protocol analyzer supporting NVM Express (NVMe). Since that time Teledyne LeCroy has added decoding for SATA Express (AHCI/PCIe) and specific probing for U.2 (SFF-8639) and M.2 connector-based storage system and devices. Integrating these PCIe SSD technologies into a single protocol analyzer, and adding targeted storage probing solutions, provides developers versatile tools that can show essential details regarding proper data transmission and bus performance. These tools have been critical to the success of PCIe SSD interoperability testing that has occurred over the last few years.


The Summit T34 Protocol Analyzer, Summit Z3-16 Exerciser and Test Platform, and the new interposers are available to order now.
