  • P198 U.2 / U.3 — **Agree** on comparable PCIe lane placement; **partial for sidebands/modes** — Both read **the same SFF-TA-1001 rev 1.1 and SFF-9639 rev 2.2 documents**, with matching hashes. U.3 PCIe-device assignments and the same 11 blank cells agree. U.2 puts lane 0 on E10/E11/E13/E14 and lane 3 on E17/E18/E20/E21; U.3 relocates PCIe lanes to S2-S27. A adds Wilder's U.2 test fixture; B adds Seagate Nytro 5060 and a separate U.3 universal-host column. Host/device E6 and S15, reserved versus fixture-defined HPT roles, and unused power/legacy-data contacts remain variant-specific. Shared SNIA evidence is not independent corroboration; Wilder and Seagate are additional, different device sources.

U.2 / Quad PCIe plug — SNIA reference-guide use

View and evidence limits

Device plug numbers; PCIe PET/PER names are from the host perspective (Table 5-2 note), even on the device. Physical view follows SFF-8639 device-plug drawing.

  • P198 U.2 / U.3 — **Agree** on comparable PCIe lane placement; **partial for sidebands/modes** — Both read **the same SFF-TA-1001 rev 1.1 and SFF-9639 rev 2.2 documents**, with matching hashes. U.3 PCIe-device assignments and the same 11 blank cells agree. U.2 puts lane 0 on E10/E11/E13/E14 and lane 3 on E17/E18/E20/E21; U.3 relocates PCIe lanes to S2-S27. A adds Wilder's U.2 test fixture; B adds Seagate Nytro 5060 and a separate U.3 universal-host column. Host/device E6 and S15, reserved versus fixture-defined HPT roles, and unused power/legacy-data contacts remain variant-specific. Shared SNIA evidence is not independent corroboration; Wilder and Seagate are additional, different device sources.
  • Reference-guide map, not a replacement for the PCI-SIG using specification. Blank use-case cells remain unverified.
  • SFF-9639 expressly warns in section 5 that its tables are a reference guide and the using-interface specifications are definitive. Blank cells were not converted to NC/reserved. The PCI-SIG U.2 module specification was not obtained in this pass.

U.3 / SFF-TA-1001 universal host receptacle

View and evidence limits

Use the separate host-receptacle/device-plug columns. PET/PER on a device still use host-perspective naming; E6 and S15 differ between host and device.

  • P198 U.2 / U.3 — **Agree** on comparable PCIe lane placement; **partial for sidebands/modes** — Both read **the same SFF-TA-1001 rev 1.1 and SFF-9639 rev 2.2 documents**, with matching hashes. U.3 PCIe-device assignments and the same 11 blank cells agree. U.2 puts lane 0 on E10/E11/E13/E14 and lane 3 on E17/E18/E20/E21; U.3 relocates PCIe lanes to S2-S27. A adds Wilder's U.2 test fixture; B adds Seagate Nytro 5060 and a separate U.3 universal-host column. Host/device E6 and S15, reserved versus fixture-defined HPT roles, and unused power/legacy-data contacts remain variant-specific. Shared SNIA evidence is not independent corroboration; Wilder and Seagate are additional, different device sources.
  • Single x4 PCIe lane numbers shown; dual-port use redistributes lane numbering. Blank source cells remain unverified.
  • SFF-9639 expressly warns in section 5 that its tables are a reference guide and the using-interface specifications are definitive. Blank cells were not converted to NC/reserved. The PCI-SIG U.2 module specification was not obtained in this pass.
  • Only the explicit SFF-TA-1001 host/PCIe device columns and single-x4 numbering are mapped. SAS/SATA protocol-specific uses, dual-x2 remaps, Gen-Z and NVMe-oF are not silently combined into those variants; Tables 4-4/4-7 and SFF-9639 Table 6-1 must be followed for the selected mode.

U.3 / SFF-TA-1001 PCIe device plug

View and evidence limits

Use the separate host-receptacle/device-plug columns. PET/PER on a device still use host-perspective naming; E6 and S15 differ between host and device.

  • P198 U.2 / U.3 — **Agree** on comparable PCIe lane placement; **partial for sidebands/modes** — Both read **the same SFF-TA-1001 rev 1.1 and SFF-9639 rev 2.2 documents**, with matching hashes. U.3 PCIe-device assignments and the same 11 blank cells agree. U.2 puts lane 0 on E10/E11/E13/E14 and lane 3 on E17/E18/E20/E21; U.3 relocates PCIe lanes to S2-S27. A adds Wilder's U.2 test fixture; B adds Seagate Nytro 5060 and a separate U.3 universal-host column. Host/device E6 and S15, reserved versus fixture-defined HPT roles, and unused power/legacy-data contacts remain variant-specific. Shared SNIA evidence is not independent corroboration; Wilder and Seagate are additional, different device sources.
  • Single x4 PCIe lane numbers shown; dual-port use redistributes lane numbering. Blank source cells remain unverified.
  • SFF-9639 expressly warns in section 5 that its tables are a reference guide and the using-interface specifications are definitive. Blank cells were not converted to NC/reserved. The PCI-SIG U.2 module specification was not obtained in this pass.
  • Only the explicit SFF-TA-1001 host/PCIe device columns and single-x4 numbering are mapped. SAS/SATA protocol-specific uses, dual-x2 remaps, Gen-Z and NVMe-oF are not silently combined into those variants; Tables 4-4/4-7 and SFF-9639 Table 6-1 must be followed for the selected mode.

Device manual Table 23 contact numbers. SG1/SG2 are separate ground features and are not counted among the 68 P/S/E contacts.

  • P198 U.2 / U.3 — **Agree** on comparable PCIe lane placement; **partial for sidebands/modes** — Both read **the same SFF-TA-1001 rev 1.1 and SFF-9639 rev 2.2 documents**, with matching hashes. U.3 PCIe-device assignments and the same 11 blank cells agree. U.2 puts lane 0 on E10/E11/E13/E14 and lane 3 on E17/E18/E20/E21; U.3 relocates PCIe lanes to S2-S27. A adds Wilder's U.2 test fixture; B adds Seagate Nytro 5060 and a separate U.3 universal-host column. Host/device E6 and S15, reserved versus fixture-defined HPT roles, and unused power/legacy-data contacts remain variant-specific. Shared SNIA evidence is not independent corroboration; Wilder and Seagate are additional, different device sources.
  • Device-specific implementation; do not use it as a universal U.2/U.3 replacement.
  • SFF-9639 expressly warns in section 5 that its tables are a reference guide and the using-interface specifications are definitive. Blank cells were not converted to NC/reserved. The PCI-SIG U.2 module specification was not obtained in this pass.
  • Only the explicit SFF-TA-1001 host/PCIe device columns and single-x4 numbering are mapped. SAS/SATA protocol-specific uses, dual-x2 remaps, Gen-Z and NVMe-oF are not silently combined into those variants; Tables 4-4/4-7 and SFF-9639 Table 6-1 must be followed for the selected mode.
