Summary

Teledyne LeCroy has announced industry’s first EDSFF interposer for SSD protocol analysis: EDSFF interposer. It combines some advanced technologies and give the SSD better performance. Read this post to get some related information.

Teledyne LeCroy Introduces the Latest Interposer Card

You know Teledyne LeCroy is a worldwide leader in protocol test solutions. Recently, it introduces its latest interposer card for analysis of enterprise and datacenter small form factor (EDSFF) E1.S as well as E1.L type solid-state drives (SSDs) and devices.

This ESDFF interposer can work with the Summit family of protocol analyzers. It is using the PCI Express® (PCIe) 4.0 specification with data rates from 2.5 GT/s to 16 GT/s and link widths of up to x4. You can see its advantages are obvious.

Teledyne LeCroy EDSFF Interposer for SSD Protocol Analysis

Indeed, EDSFF devices are important and growing segment in the storage devices market. The EDSFF interposer card, which is also known as the ruler SSD (RSSD) form factor, can work with the Summit PCIe protocol analyzer to monitor, capture, and record PCIe traffic between a host backplane and EDSFF devices.

Development Situation of EDSFF Devices

At present, the engineers who are developing and troubleshooting EDSFF devices master an effective way to capture and analyze the transmitted PCIe 4.0 data.

John Wiedemeier, Sr. is the Product Marketing Manager in the Protocol Solutions Group, Teledyne LeCroy. According to the words from him, the EDSFF SSD has a huge market. The engineers from the company do their best to develop this product. Their rich experience will largely shorten the development and testing period.

Tip: Data loss issue always happens by mistake. If you lose your important files on SSD, you can use MiniTool Power Data Recovery, a professional data recovery software, to rescue them.

The interposer supports PCIe host interfaces like the NVM Express (NVMe) protocol with data rates up to 16 GT/s and link widths up to x4.

In addition, the PCIe 4.0 x4 EDSFF Interposer can offer connectivity and monitoring capability for E1.S or E1.L type devices aimed at enterprise systems that utilize the SFF-TA-1002 multi-lane card edge connector.

With this EDSFF Interposer, four form factor types can be analyzed, including the EDSFF 1U short/narrow and EDSFF 1U short/wide form factors as defined in SFF-TA-1006 specification as well as the two 1U long version form factors as defined in the SFF-TA-1007 specification.

The EDSFF interposer tracks all PCIe protocol traffic between the host and EDSFF device/SSD and then records it on the Summit PCIe 4.0 protocol analyzer where protocol problems and performance metrics can be further analyzed and debugged.

Industry's First PCIe 4.0 x4 EDSFF Interposer for SSD Protocol Analysis

Indeed, this is the world’s first industrial PCI Express protocol analyzer with NVMe decoding functionality. After it was first announced, the company has added decoding for SCSI Express (SOP/PQI) and SATA Express (AHCI/PCIe).

Combining all of these three PCIe SSD technologies into a single protocol analyzer can offer developers versatile tools which can show essential details regarding proper data transmission and bus performance. Over the past years, these tools are always the core of the PCIe SSD interoperability testing.

Good news is that this PCIe 4.0 x4 EDSFF interposer is available now. You can order it by contacting the company. Just visit its official site to get contact information of the company.
