Overview
The VIAVI Xgig U.3-Server 4-lane Interposer for PCI Express 5.0 (Xgig5P-PCIe5-X4-U3B) is an active interposer for development, debugging and performance tuning of NVMe SSD operation in high-density storage servers. It captures bidirectional PCIe 5.0 protocol data on 4 lanes at 32GTps and passes it to a VIAVI PCIe 5.0 Analyzer. The interposer supports either 1 link of 4 lanes or 2 links of 2 lanes for dual-port operation, and is compliant with the SFF-TA-1001 connection standard for PCIe signals.
High-speed linear signal redrivers restore the signal quality of the PCIe data lanes across the interposer between the host system and the SSD under test, so that a clean signal reaches the Analyzer for protocol capture and analysis.
Construction
The Front-end module has the same physical size as a 2.5-inch SSD, so it can be inserted into the drive carrier normally used with the server; a lightweight handle can be attached instead for drive insertion. Flex cables allow the Back-end module, which holds the U.3 NVMe SSD under test, to lie on top of the server or on the lab bench. Adjustable tray clamps, shims and a quick-release latch hold the SSD in place and allow it to be swapped quickly. A supplied power brick makes the interposer power independent of the host system.
Operation
The interposer works with the VIAVI Xgig 5P8 and 5P16 PCIe 5.0 analysis chassis, connected through custom high-performance cables, with Xgig analysis tools running on a local or remote Windows PC. In Analyzer mode, data is tapped from both the upstream and downstream paths. In Jammer or Analyzer/Jammer mode, data flows through the Analyzer and is retimed for transmission, enabling error injection. In Analyzer/Exerciser mode, data flows through the interposer to the DUT, supporting endpoint emulation.
Typical uses include debugging and verifying new NVMe controller ICs, new system implementations and firmware, validating system BIOS and software, and quality assurance in manufacturing test.
