Haku-saareyaasha oo ka mid ah: : The host system initiates the process by creating a dedicated Submission Queue (SQ) and Completion Queue (CQ) pair for latency measurement. This isolation prevents interference from other I/O operations. The start addresses and lengths of these queues are configured in the FPGA’s test logic. Queue Pair Creation : The host queues an NVMe command and rings the doorbell, prompting the device to fetch the command from the SQ. Command Injection : The device issues a PCIe Transaction Layer Packet (TLP) to fetch the command. The FPGA’s snooping logic monitors for read requests within the SQ address range, retrieves the transaction Tag (a unique identifier for the transaction), and records it internally. PCIe Transaction Snooping : As the FPGA continues monitoring, it matches the Tag in subsequent response packets, extracts the NVMe command ID from the TLP payload, and starts a high-resolution latency timer—typically driven by FPGA clock cycles in the nanosecond range. Tag Matching and Timer Start : The FPGA then watches for command completion responses in the CQ address range. When the NVMe command ID in the completion response matches the saved command ID, the timer stops, and the measured latency is reported back to the host.

Integration Flexibility Taageerada oo ku saabsan Ecosystem Storage : Cloud providers and enterprise IT teams can use this technology for real-time latency analytics across large fleets of NVMe devices, enabling dynamic QoS management and proactive troubleshooting. Data Center Optimization : Manufacturers can integrate this IP into test platforms to validate SSD latency under extreme workloads, replacing expensive and less flexible protocol analyzers. Storage OEM Validation : In latency-sensitive environments like autonomous vehicles or industrial edge computing, Sindhu’s method provides the granularity needed to certify storage subsystems for real-time operation. Autonomous and Edge Systems : As CXL adoption grows for memory pooling and computational storage, the patent’s PCIe snooping framework lays the groundwork for similar measurement techniques across new protocols.
