PCI-SIG
Founded in 1992, PCI-SIG defines interoperable high-speed bus standards, form-factors, and runs compliance programs. The PCI Express interface doubles bandwidth each generation—while maintaining backward compatibility—so new platforms can eliminate data-movement bottlenecks and sustain AI performance across CPUs, GPUs, and accelerators.
SNIA and PCI-SIG collaborate through a formal liaison agreement to advance interoperability between PCI Express® technologies and the storage ecosystem. The alliance enables coordination across enterprise storage form factors, high-speed cabling, connectors, and PCIe-based device integration supporting modern data center architectures.
Collaboration between SNIA and PCI-SIG focuses on aligning SNIA Small Form Factor (SFF) specifications with the PCI Express specification suite to ensure interoperability across modern data center platforms. Defined work areas include Enterprise and Datacenter Standard Form Factor (EDSFF) technologies, enterprise drive form factors and connector ecosystems (including U.2), multi-lane internal and external high-speed cabling, PCIe external cabling and OptiLink technologies, and related pin and signal definitions.
Through structured information sharing and technical engagement, experts from both organizations exchange feedback, review specifications, and coordinate alignment efforts that support scalable enterprise, cloud, and AI infrastructure. The liaison framework also enables ongoing exploration of future interoperability opportunities, including advancements in EDSFF, I3C, and flexible I/O enablement.
