The MA-L block F4:15:32 is registered to "PETAiO (NanJing), Inc." at 17/F, Block A, Weien Building, No. 73 Huachuang Road, Yan Chuang Park, Jiang Bei New Area, Nanjing, Jiangsu, CN 211800. PetaIO (Chinese name 鹏钛存储) is an enterprise storage company founded in 2017 and headquartered in Nanjing, China, that designs SSD host-controller chips and ships enterprise NVMe SSDs in U.2, M.2, E1.S, and AIC form factors. Its products target hyperscale data centers, cloud computing, and distributed storage, and its self-developed controller families (Titanium DC, Titanium XP) advertise support for PCIe 5.0, CXL 2.0, NVMe 2.1, and OCP 2.5. An OUI assignment for a storage-controller vendor is consistent with enterprise SSD/CXL devices that expose a network- or PCIe-addressable identity in data-center fabrics. A standard OUI caveat applies: IEEE publishes no registration date for OUI/MAC prefix assignments, so any "date registered" surfaced by third-party MAC lookup tools is a database artifact, not an IEEE fact, and is recorded here as Unknown. No public CVEs or supply-chain security incidents specific to PetaIO were found as of June 2026.

- Analyst note
- an F4:15:32 globally-administered address identifies genuine PetaIO-registered hardware (an enterprise storage controller/SSD); as with any OUI, randomized/locally-administered MACs and re-badged silicon mean OUI alone is not a complete asset identifier.
