Very High Density Cable Interconnect (VHDCI) is a compact 68-contact multipurpose connection type.
VHDCI is optimized for applications that require high-performance but have space limitations. The technology is most commonly used in SCSI-3 attached hard drives, which was the purpose it was originally designed for. VHDCI is also used in RAIDs, SANs, and other storage arrays.
VHDCI can function as a multi-monitor connector, each supporting two DVI connections for display. Despite having many contact pins, VHDCI’s smaller size makes it possible to fit four connectors on a PCIe back-plate. That capacity enables support of up to eight monitors on a single graphics card. Performing as an external eight-lane PCIe, VHDCI can connect other devices and systems, as seen in Nvidia Quadroplex video processing arrays.
