Supermicro CBL-MCIO-1270S4T3 - kábel

Internal NVMe cable engineered for high-density storage connectivity, delivering a single MCIO x8 host interface to four OCuLink x4 device ports over a 127 cm span. This passive copper assembly supports PCIe Gen5 signaling and is backward compatible with Gen4, making it a dependable backbone for U.2/U.3 NVMe drive backplanes in Supermicro server and workstation platforms.

Advantages

By consolidating eight host lanes into four independent x4 links, the cable reduces cable clutter while preserving full bandwidth per drive. The MCIO connector's compact footprint improves airflow over traditional multiple SFF-8643 cables, and the 127 cm length offers flexibility in mid-tower and rackmount chassis. RoHS-compliant materials and a black jacket ensure long-term reliability and a clean internal appearance.

Suitable for

• Supermicro motherboards and HBAs with MCIO x8 ports
• NVMe U.2/U.3 drives or backplanes with OCuLink x4 (SFF-8611) connectors
• PCIe Gen4 and Gen5 storage arrays requiring internal cabling
• Server and workstation builds where space and airflow are critical

Key specifications

• Host connector: MCIO x8 (8 lanes)
• Device connectors: 4x OCuLink x4 (SFF-8611), 4 lanes each
• Cable length: 127 cm (1.27 m)
• Data transfer protocol: NVMe
• PCIe generation support: Gen5 (backward compatible with Gen4)
• Material: Copper conductors, black jacket
• RoHS compliant: Yes

Recommendations

Pair with Supermicro NVMe backplanes or drive cages that feature OCuLink inputs to maximize storage density. Verify that your host controller provides an MCIO x8 port before installation. For Gen5 environments, ensure all connected drives and backplanes are Gen5-rated to achieve full performance.
