Overview
The M.2 form factor is the dominant SSD interface across laptops, desktops, workstations and servers, and its support for NVMe over PCIe makes it a key connection point for storage development and validation. The VIAVI Xgig 4-lane M.2 Interposer (Xgig6P-PCIe6-X4-MD2M) is an active interposer designed for M.2 SSD development. It enables protocol analysis of communication between an M.2 PCIe SSD and the host system, capturing bidirectional PCIe 6.0 data on each of 4 lanes at up to 64GT/s.
The interposer works together with the VIAVI Xgig 6P16 analysis platform chassis. It supports use in servers, workstations, desktop and notebook PCs, and other system types, and is applied to debug and verification of new M.2 PCIe SSD cards and system implementations, firmware development, validation of system BIOS and software, and manufacturing test.
High-speed linear signal redrivers buffer the system data signals so that a clean signal is delivered to both the analyzer and the device under test, supporting accurate protocol capture and full decode of data traffic and link states. Low-loss custom high-performance cables are supplied for the connection to the VIAVI analyzer.
Setup and operation
The PCIe SSD is mounted into the interposer's M.2 card tray and the interposer is cabled to the VIAVI analysis platform chassis. The M.2 DUT cable and PCB are then installed in the system under test and plugged into the interposer pod. Data flows between the host CPU and the SSD as normal and is tapped for the analyzer. In analyzer mode, both upstream and downstream data are tapped as analyzer inputs; in Analyzer/Exerciser mode, data flows through the interposer to the DUT.
