MCX555A-ECAT Overview

Intelligent RDMA-enabled network adapter card with advanced application offload capabilities for High-Performance Computing, Web2.0, Cloud, and Storage platforms

ConnectX-5 with Virtual Protocol Interconnect supports two ports of 100Gb/s InfiniBand and Ethernet connectivity, sub-600 ns latency, and very high message rate, plus PCIe switch and NVMe over Fabric offloads, providing the highest performance and most flexible solution for the most demanding applications and markets: Machine Learning, Data Analytics, and more.

HPC Environments

ConnectX-5 delivers high bandwidth, low latency, and high computation efficiency for high performance, data intensive and scalable compute and storage platforms. ConnectX-5 offers enhancements to HPC infrastructures by providing MPI and SHMEM/PGAS and Rendezvous Tag Matching offload, hardware support for out-of- order RDMA Write and Read operations, as well as additional Network Atomic and PCIe Atomic operations support.

ConnectX-5 VPI utilizes both IBTA RDMA (Remote Data Memory Access) and RoCE (RDMA over Converged Ethernet) technologies, delivering low-latency and high performance. ConnectX-5 enhances RDMA network capabilities by completing the Switch Adaptive-Routing capabilities and supporting data delivered out-of- order, while maintaining ordered completion semantics, providing multipath reliability and efficient support for all network topologies including DragonFly and DragonFly+.

ConnectX-5 also supports Burst Buffer offload for background checkpointing without interfering in the main CPU operations, and the innovative transport service Dynamic Connected Transport (DCT) to ensure extreme scalability for compute and storage systems.

FAQs

Frequently Asked Questions

What are the primary interface capabilities of the Mellanox MCX555A-ECAT? +

The MCX555A-ECAT is a versatile Virtual Protocol Interconnect (VPI) adapter. It supports both 100Gb/s EDR InfiniBand and 100GbE Ethernet connectivity via a single QSFP28 port. This flexibility allows IT architects to standardize on one hardware platform for both high-performance computing clusters and high-bandwidth Ethernet data center fabrics.

Does the MCX555A-ECAT support PCIe 3.0 or PCIe 4.0 slots? +

This specific model utilizes a PCIe 3.0 x16 interface. It is designed to provide full line-rate performance for 100Gb/s throughput when installed in a server with sufficient PCIe 3.0 lanes available. Ensure your server motherboard has a compatible physical x16 slot to accommodate the card's form factor and throughput requirements.

What physical form factor does the MCX555A-ECAT utilize? +

The MCX555A-ECAT comes equipped with a tall bracket, making it ideal for standard 2U or larger rack-mount servers. The card's single-port QSFP28 design is optimized for high-density networking environments where cable management and airflow are critical considerations for consistent thermal performance.

Can the MCX555A-ECAT handle low-latency requirements for HPC applications? +

Yes, as part of the ConnectX-5 family, this adapter is engineered for extremely low latency and high message rates. It features advanced offloading capabilities, including hardware-based RDMA (Remote Direct Memory Access) and RoCE (RDMA over Converged Ethernet), which are essential for minimizing CPU overhead in demanding clustered application environments.

Is the MCX555A-ECAT suitable for virtualization and cloud deployments? +

Absolutely. This adapter includes Mellanox Multi-Host technology and SR-IOV support, enabling efficient virtual machine scaling. It allows for the partitioning of a single physical port into multiple virtual functions, ensuring that virtualized workloads receive near-native networking performance while reducing the total number of required network adapters in the infrastructure.

Does this NIC support existing 100GbE switch infrastructure? +

The MCX555A-ECAT is fully compliant with IEEE 802.3 standards for 100GbE. It will interoperate seamlessly with any standard-compliant 100GbE QSFP28 switch. Whether you are using it in Ethernet mode for data center traffic or InfiniBand mode for storage backends, it provides broad compatibility across major enterprise switch vendors.

How does the ConnectX-5 architecture improve CPU efficiency? +

The ConnectX-5 VPI adapter offloads networking tasks such as packet inspection, crypto offloads, and flow steering directly to the card. By offloading these compute-intensive processes from the host processor, the MCX555A-ECAT frees up significant CPU cycles, allowing your servers to dedicate more resources to actual application processing.

What is the recommended power consumption profile for this card? +

While power draw can fluctuate based on traffic load and link type (Ethernet vs. InfiniBand), this card is optimized for high-efficiency data center use. It is designed to adhere to standard PCIe power specifications, ensuring stable operation within the thermal envelopes typical for modern, high-performance enterprise server configurations.
