Frequently Asked Questions

What is the primary interface and data rate for the Mellanox MCX311A-XCAT? +
The MCX311A-XCAT is a high-performance ConnectX-3 EN network interface card featuring a single SFP+ port. It supports 10GbE Ethernet connectivity, making it an ideal solution for bandwidth-intensive applications that require low latency and high throughput in data center or enterprise server environments.
What PCIe generation and lane configuration does this NIC require? +
This adapter utilizes a PCIe 3.0 x8 interface to ensure maximum data transfer efficiency between the network and the host system. It is backward compatible with PCIe 2.0 slots, though performance may be limited by the bandwidth constraints of the older interface generation.
Is the MCX311A-XCAT compatible with common virtualization environments? +
Yes, this card supports advanced virtualization features, including hardware-based I/O virtualization and SR-IOV. These capabilities allow the NIC to provide efficient resource sharing among multiple virtual machines, significantly reducing CPU overhead and improving overall network performance in dense virtualized server deployments.
Can this Mellanox card be used in low-profile server chassis? +
The MCX311A-XCAT is typically supplied in a standard form factor, but its physical design is compatible with many server architectures. Please verify your specific chassis clearance and bracket requirements, as this card is designed for high-density environments where standard PCIe expansion slots are available for high-speed network connectivity.
Does this NIC support RDMA over Converged Ethernet (RoCE)? +
The ConnectX-3 architecture is well-regarded for its support of RDMA over Converged Ethernet (RoCE). This technology allows for direct memory access between servers, bypassing the OS kernel to achieve ultra-low latency and reduced CPU utilization, which is essential for high-performance computing and storage area network applications.
What operating systems are supported by the MCX311A-XCAT drivers? +
Mellanox provides robust driver support for a wide array of enterprise-grade operating systems, including major Linux distributions, VMware ESXi, and Microsoft Windows Server. Users should verify the specific driver version on the manufacturer's website to ensure compatibility with their current kernel or environment version to maintain system stability.
How does the MCX311A-XCAT handle network traffic processing? +
This card utilizes hardware offloading engines for common tasks such as TCP/UDP/IP checksums and large send offload. By offloading these compute-intensive tasks from the host processor to the dedicated NIC hardware, the system can preserve CPU cycles for primary application workloads while maintaining consistent network performance.
What type of transceiver modules can I use with this SFP+ port? +
The SFP+ port on this card is designed for flexibility, supporting both direct attach copper (DAC) cables for short-reach, low-latency connections and optical transceivers for longer distances. When selecting transceivers, ensure they are compatible with the 10GBASE-SR or 10GBASE-LR standards to ensure reliable communication over your preferred cabling infrastructure.
Does BuyRouterSwitch.com provide assistance for bulk purchasing of Mellanox NICs? +
Yes, we specialize in supporting large-scale enterprise rollouts. If you require a high volume of MCX311A-XCAT units for a data center upgrade or a large infrastructure project, please reach out to our sales team.
