SMUGDESK MCX555A-ECAT ConnectX-5 VPI 100G PCIe 3.0 x16 QSFP28 Network Card

SKU CH-FG0E-AFK7X

Single-port QSFP28 adapter delivering 100GbE or EDR InfiniBand with PCIe 3.0 x16, RDMA offload and ~750ns latency for HPC and NVMe storage clusters

  • Single QSFP28 port runs 100GbE or EDR InfiniBand at 100 Gbps
  • PCIe 3.0 x16 bus works in 1.1, 2.0, 3.0 and 4.0 x16 or x8 slots
  • Hardware offload for RDMA, RoCE v1/v2, NVMe-oF and GPUDirect cuts CPU load
  • Ultra-low latency around 750 ns suits HPC, AI and distributed storage
  • Full-height and low-profile brackets fit standard rack and compact SFF servers

Single-port 100G VPI adapter

The SMUGDESK MCX555A-ECAT is a new network interface card built on the NVIDIA Mellanox ConnectX-5 VPI controller. It provides a single QSFP28 port that auto-switches between 100GbE Ethernet and EDR 100Gbps InfiniBand. The card targets servers and workstations running HPC clusters, AI computing, NVMe-oF storage or cloud virtualization workloads.

PCIe 3.0 x16 slot and QSFP28 transceiver

Verify that the host has a PCIe 3.0 x16 slot; the card is also compatible with PCIe 1.1, 2.0 and 4.0 x16 or x8 motherboard slots. A matched QSFP28 optical or copper transceiver is required for the chosen 100G, 50G, 40G, 25G or 10G link rate. Driver support covers Windows Server, Linux, VMware ESXi and FreeBSD with OFED and WinOF-2 suites.

Passive heatsink for 24/7 rack duty

A large passive heatsink dissipates heat without a fan, enabling silent 24/7 operation in rack environments. Hardware offload for RDMA, RoCE v1/v2, NVMe-oF, GPUDirect, RSS, MSI-X, 9.6KB jumbo frames and IEEE 802.1Q VLAN/PFC/ETS reduces CPU overhead. Ultra-low latency of ~750ns supports sustained high-speed transmission.

Highlights

  • Single QSFP28 port runs 100GbE or EDR InfiniBand at 100 Gbps
  • PCIe 3.0 x16 bus works in 1.1, 2.0, 3.0 and 4.0 x16 or x8 slots
  • Hardware offload for RDMA, RoCE v1/v2, NVMe-oF and GPUDirect cuts CPU load
  • Ultra-low latency around 750 ns suits HPC, AI and distributed storage
  • Full-height and low-profile brackets fit standard rack and compact SFF servers

Questions about this item

Does the card include a QSFP28 transceiver or must one be purchased separately?

The adapter ships with a single QSFP28 port; transceivers and matching optical or copper cables are not included and must be bought separately.

Which speed mode should be chosen for a 100 GbE fabric versus an EDR InfiniBand fabric?

The port auto-switches between 100 GbE Ethernet and EDR 100 Gbps InfiniBand, and is backward compatible with 50G, 40G, 25G and 10G rates when paired with appropriate transceivers.

What does the 750 ns latency figure mean for real workloads?

The ultra-low 750 ns latency design reduces server CPU overhead for HPC clusters, AI computing, distributed storage and cloud virtualization, enabling stable 24/7 operation.
