Frequently Asked Questions
What are the primary performance specifications of the Mellanox ConnectX-4 Lx MCX456A-ECAT adapter? +
The MCX456A-ECAT is a dual-port 10/25GbE adapter designed for high-performance data centers. It delivers significant throughput and low latency, utilizing PCIe 3.0 x8 connectivity. This card is engineered to handle demanding enterprise workloads, providing advanced offloading capabilities that ensure efficient data transfer and reduced CPU utilization during peak network traffic.
Which interface type does the MCX456A-ECAT support for network connectivity? +
This adapter features two SFP28 ports, allowing for flexible connectivity options. It supports both 10GbE and 25GbE data rates, making it an ideal choice for organizations transitioning from 10G infrastructure to higher-speed 25GbE environments. The SFP28 interface ensures compatibility with standard optical transceivers and direct attach copper cables for various data center reaches.
What server environments is the MCX456A-ECAT compatible with? +
The MCX456A-ECAT is compatible with most standard x86 rack-mount and tower servers that feature available PCIe 3.0 expansion slots. Because it adheres to industry-standard PCIe form factors, it integrates seamlessly into heterogeneous environments running major operating systems like Linux, Windows Server, and various virtualization platforms, provided the appropriate drivers from the manufacturer are utilized.
How does this card improve server efficiency in virtualized deployments? +
By leveraging hardware-based offloading engines, the MCX456A-ECAT significantly improves efficiency in virtualized environments. It supports features like SR-IOV and RDMA over Converged Ethernet (RoCE), which allow virtual machines to bypass the hypervisor overhead. This results in reduced CPU cycles, lower latency for inter-VM communication, and overall better performance density per physical server host.
What is the physical form factor of the MCX456A-ECAT? +
The MCX456A-ECAT is manufactured in a standard low-profile PCIe form factor. This design makes it highly versatile, as it can be installed in compact 1U rack-mount servers or larger chassis using the included bracket accessories. Its compact size ensures it does not obstruct airflow or interfere with other components within densely packed server environments.
Is the MCX456A-ECAT suitable for storage-intensive networking applications? +
Absolutely. Thanks to its support for RoCE and high-bandwidth 25GbE throughput, this card is exceptionally well-suited for storage-area network (SAN) and network-attached storage (NAS) applications. It enables fast, low-latency data access that is critical for high-performance storage clusters and enterprise-level database management, helping to eliminate network bottlenecks often found in standard storage deployments.
Does the MCX456A-ECAT require specific driver installations? +
Yes, optimal functionality and performance of the MCX456A-ECAT require the installation of the latest Mellanox OFED (OpenFabrics Enterprise Distribution) drivers or the native inbox drivers provided by your specific operating system. Keeping these drivers up to date is essential for ensuring compatibility with the latest firmware releases, security patches, and advanced network acceleration features.
What cooling requirements should be considered for this network interface card? +
The MCX456A-ECAT is designed to operate within the standard thermal envelopes of enterprise-grade servers. It relies on the chassis-level forced-air cooling system to maintain safe operating temperatures. To ensure reliability and longevity, it is important that the host server provides adequate airflow across the PCIe slots and that the ambient room temperature remains within the manufacturer's specified range.
