Cable Supermicro Mini Cool Edge IO x8 to Slim SAS x8 45cm PCIe Gen5 CBL-MCIO-1270S4T2

This Supermicro CBL-MCIO-1270S4T2 cable is a 45 cm Mini Cool Edge IO x8 to Slim SAS x8 assembly designed for PCIe Gen5 environments. It provides an x8 lane electrical connection between a Mini Cool Edge IO connector and a Slim SAS x8 receptacle, enabling high-bandwidth links in rack servers, storage enclosures, and workstation configurations that require compact, low-profile cabling. The cable is intended for internal system use where PCIe Gen5 throughput and signal integrity are required over a short, direct connection.

Advantages

The cable supports PCIe Gen5 signal rates across an x8 lane configuration while maintaining a compact form factor suitable for dense server and storage layouts. Its 45 cm length allows flexible routing within chassis without excess slack. The Mini Cool Edge IO and Slim SAS connectors offer a low-profile mechanical footprint, enabling compatibility with tight internal spaces and standard drive backplanes. Overall, the design emphasizes reliable high-speed data transmission and straightforward installation in compatible systems.

Suitable for

• Connecting controller cards to drive backplanes in servers and storage enclosures
• Internal high-speed links in PCIe Gen5-capable systems
• Compact rackmount or dense chassis deployments where low-profile cabling is required
• Upgrading or building storage arrays that use Slim SAS x8 interfaces

Key specifications

• Connector A: Mini Cool Edge IO x8 (internal)
• Connector B: Slim SAS x8 (internal)
• Lane configuration: x8 electrical lanes
• Length: 45 cm
• Supported interface: PCI Express Gen5 signaling
• Orientation: Low-profile, internal cable assembly for chassis routing

How to use

Install the cable by plugging the Mini Cool Edge IO x8 end into the designated Mini Cool Edge connector on the controller or host card, and insert the Slim SAS x8 end into the corresponding drive backplane or enclosure port. Ensure both connectors are fully seated and any retention mechanisms are engaged to secure the connection. Route the cable to avoid sharp bends and contact with heat sources or moving parts inside the chassis. Verify system firmware and drivers support PCIe Gen5 operation for full bandwidth availability.

Usage recommendations

For optimal performance, keep the cable length and routing as direct as possible, avoid tight radii when bending, and confirm compatibility with your server or storage platform's internal connector layout. Use static-safe practices when installing the cable and power down the system before making or removing internal connections.
