Current quantity and pricing are confirmed at RFQ.Product overview
MCX556A-ECAT is the exact legacy OPN for an NVIDIA ConnectX-5 VPI adapter with two 100Gb/s QSFP28 ports for EDR InfiniBand or 100GbE and a PCIe 3.0 x16 host interface. NVIDIA lists the product line as end-of-life, making exact-part verification relevant for installed-base spares and legacy sourcing. Buyers planning simultaneous traffic across both ports should account for NVIDIA's documented PCIe host-bandwidth limitation; current availability is confirmed by RFQ.

Lifecycle & procurement context
Manufacturer lifecycle: Discontinued / EOL
MCX556A-ECAT has two network ports capable of up to 100 Gb/s each, but NVIDIA states that the PCIe 3.0 x16 host interface cannot support the theoretical 200 Gb/s aggregate bandwidth when both ports operate at 100 Gb/s.
Lifecycle is manufacturer product status, not a statement of current stock. Availability and price are confirmed by RFQ.
