NVMe Protocol Analysis Features for Storage Development and Test36:27

As storage developers make the transition from legacy SAS and SATA protocol-based SSDs to the more advanced NVMe and SATA Express technologies, they are encountering limitations in available design and test tools including limited trace recording times and a lack of standardized analysis reports for PCIe-based storage. These two issues are significant for the newer technologies of NVMe and SATA Express due to the following:

  • High performance SSD testing can require recording data traffic beyond a few minutes. This is not possible for many protocol analyzers due to limitations in their recording architectures.
  • While some test tool suppliers have claimed support for the NVMe and SATA Express protocols, support for these protocols has remained minimal. This has hampered developer's productivity due to the use of reporting systems designed for the older technologies, which are not optimized for quality testing on NVMe and SATA Express products.

The Summit T34 protocol analyzer, specifically targeted at PCIe storage applications, now supports long trace recordings with a new NVMe Enhanced Mode. The Summit T34 can also be configured with up to 64 GB of trace recording memory. NVMe Enhanced Mode builds on and optimizes the existing deep buffer memory to allow users long recording time capability. Depending on the speed of the DUT (Device Under Test), the recording time can be maximized to up to several hours for a single trace capture. This feature is useful for tasks such as measuring performance or determining how well your Queue handling algorithms are functioning. An example of the metrics that are now available include the ability to measure the NVMe queue distribution over a sustained period of time. The ability to gather queue behavior for long periods helps driver and OS developers fine tune their applications and balance queue loads for optimized product performance.

With over a decade of experience in providing PCI Express, SAS/SATA and other serial data protocols with standardized error analysis and product performance reports, Teledyne LeCroy has now created an NVMe and SATA Express SSD Performance and Analysis capability. Trace Expert™, a new feature in the PCIe Protocol Suite, creates a detailed report that the SSD industry requires to obtain a common understanding of how their SSD or storage systems are operating and includes information on the necessary PCIe based components. Information such as NVMe queues, commands, doorbell and control registers and many other metrics are captured, analyzed and organized into a detailed report providing developers a comprehensive status document for their products including a wide range of performance statistics.

In addition to the standard storage protocols, all of our NVMe platforms also fully support, Trusted Computer Group (TCG), Single Root I/O Virtualization (SRIOV), Multi-Root I/O Virtualization (MRIOV) and Address Translation Services (ATS). A full list of capabilities, views and reports can be found on the product pages (listed below) for each of our analyzers.

The Summit Z416 exerciser is Teledyne LeCroy's fifth generation PCI Express (PCIe) protocol exerciser, leveraging years of experience in providing advanced protocol test tools to the PCI Express community. Supporting traffic generation at data rates to 16 GT/s with link widths up to 16 lanes, the system is designed for developers who need a protocol test system supporting the PCI Express 4.0 specification.

In addition to traffic generation, the system also supports protocol analysis capability, featuring the industry-standard CATC Trace as well as a wide variety of other traffic displays and data reports. The Summit Z416 supports full traffic generation and device/host emulation, as well as providing the industry a platform for development of standardized compliance test suites. In addition the system provides error injection functions to enable developers to test error recovery routines important to reliable interoperability of PCI Express 4.0 products.

A Wealth of Features

Intuitive software controls blend sophisticated traffic generation and analysis capability with ease-of-use, allowing test suites to be rapidly customized to meet specific test requirements. One feature that helps troubleshoot PCIe links is the ability to fully exercise the Link Training & Status State Machine (LTSSM) transitions. The powerful scripting language also allows for the creation of Transaction Layer Packets (TLPs) and Data Link Layer Packets (DLLPs) at PCIe 4.0 data rates of 16 GT/s. Flow Control and ACK/NAK's policies and structures can be defined and generated under user control. Features addressing LTSSM structures include providing bus traffic to emulate the all states of the LTSSM from the Detect state, to the L0 state and maintaining the L0 state between the host and device. The exerciser also supports lane reversal and can control all polarity and scrambling configurations. An important feature to note is that traffic emulation supports dynamic equalization and Skip EQ training and can handle autonomous speed switching between all combinations of speeds. The exerciser also has the capability to perform error injection for training sequences, as well as standard traffic, both at the packet level and on a per lane basis. Packet fields not explicitly specified by the user are generated automatically (such as packet numbering and CRCs). The configuration space can be emulated for any device including endpoints, bridges and switches. Support for all PCIe 4.0 data rates allows the Summit Z416 to produce test cases that test the device's ability to auto-negotiate data rates with other devices. In addition, the ability of the Summit Z416 to produce a wide variety of programmed traffic allows the user to introduce controlled error conditions. As an example, a trace file captured in the Analyzer can be exported and used as the basis for a test script, with selected programmed errors, introduced at critical stages to test the device's ability to recognize an recover from error conditions. This allows for detailed testing of simple error recovery and complex multiple error conditions, creating more resilient products that perform well even under less than ideal conditions.

Protocol Analysis Included

The Summit Z416 can also support up to sixteen (16) lanes of protocol analysis. Using its high speed trace memory (up to 8 GB), the Summit Z416 can monitor, capture, decode and analyze PCIe protocols with data rates up to 16GT/s (Gen4). The application display is highly configurable and can be modified to most users' debugging styles. Many features are available including a hierarchical display, protocol traffic summaries, detailed error reports, timing calculators, bus utilization graphs, and the ability to create userdefined test reports allowing developers to troubleshoot intricate problems and finish their projects on time. PCIe storage decodes such as NVMe, SATA Express (AHCI and ATA), SCSI Express (PQI and SOP), TCG (Trusted Computing Group), Precision Time Management (PTM) and virtualization decode such as Single and Multi-Root I/O Virtualization (SRIOV and MRIOV) as well as Address Translation Services (ATS) are available to broaden its capabilities to many different industry segments.

Test Platform

PXP-400 Test Platform provides Host Emulation Teledyne LeCroy's PCIe 4.0 Test Platform for the Summit Z416 Protocol Exerciser provides a convenient, powerful and flexible two CEM compliant backplane for PCIe devices at data rates up to 16 GT/s and with lane widths up to x16. The Test Platform allows the Summit Z416 to act as a host system, enabling extensive protocol-level esting of PCIe devices. For use as a host emulator, the Summit Z416 is plugged into one of the PCIe x16 slots and connected to the power source, then the Device Under Test (DUT) is plugged into the alternate PCIe x16 slot with slot power provided to the DUT by the Test Platform. In addition to using the Test Platform with the Teledyne LeCroy Summit Z416, the user can connect two of their own devices and use the Test Platform as a PCIe backplane.

Test Fixtures

Two test fixtures are also available to help with testing PCIe 4.0 devices: a PCIe Verification Load Board (VLB) for testing PCIe platforms such as server or mother boards, and the PCIe Validation Base Board (VBB) for testing PCIe Add-in Cards. Each of these test fixtures will aid developers in conducting electrical tests.
