Overview
Host Management is the distinguishing label on the NVIDIA MCX516A-CCHT. Besides two QSFP28 ports at 100GbE and a PCIe Gen3 x16 interface, the title lists UEFI, so this is the build intended for systems where the adapter participates in host-level management and boots under UEFI.
That makes the exact MPN important. A card with the same speed and ports but without those features will not match a bill of materials that calls for them. If your server vendor specified this number, buy the same number.
Two 100GbE ports are enough to uplink to a redundant pair of switches or to feed a storage-heavy host. Plan QSFP28 modules or cables for each cage and confirm the slot is a full x16.
The NVIDIA code 900-9X5AD-0056-ST6 is recorded as an alternative part number. We offer refurbished and used stock. Refurbished units carry a warranty choice of 1 year or 3 years, and used units carry 90 days. Request pricing and include the quantity and server model.
