Frequently Asked Questions
What are the primary performance specifications of the Mellanox ConnectX-3 MCX312B-XCCT? +
The MCX312B-XCCT is a dual-port 10GbE adapter designed to deliver high-bandwidth performance with low latency. It supports PCIe 3.0 x8 connectivity, ensuring efficient data throughput for demanding enterprise applications. This card is engineered to handle intensive I/O workloads, making it an excellent choice for data centers requiring consistent, high-speed networking performance.
Which operating systems and software environments are compatible with this NIC? +
This Mellanox adapter is highly versatile, supporting a broad range of operating systems including major Linux distributions, Windows Server editions, and various virtualization platforms like VMware ESXi. By utilizing standard drivers and Mellanox's robust software stack, it integrates seamlessly into existing enterprise infrastructure, providing reliable connectivity across diverse hardware and software ecosystems.
Does the MCX312B-XCCT support hardware offloading technologies? +
Yes, this card features advanced hardware offloading capabilities, including stateless offloads for TCP, UDP, and IP. By offloading these protocol-processing tasks from the host CPU, the MCX312B-XCCT significantly reduces processor overhead. This allows your server to dedicate more cycles to core business applications, effectively increasing overall system efficiency and reducing latency in virtualized or high-performance computing environments.
What type of physical connectivity does the MCX312B-XCCT utilize? +
The card is equipped with two SFP+ ports, which provide the flexibility to use various 10GbE fiber-optic transceivers or direct-attach copper (DAC) cables. This physical interface allows for versatile deployment options, enabling you to choose the appropriate media type that best fits your distance requirements and existing switch port infrastructure within your server rack.
Is the MCX312B-XCCT suitable for high-frequency trading or low-latency clusters? +
Absolutely. The ConnectX-3 series is widely recognized for its ultra-low latency architecture. Designed specifically for high-performance computing (HPC) and sensitive financial applications, this card excels at minimizing packet processing time. Its ability to maintain high throughput with minimal jitter makes it a reliable choice for time-sensitive network traffic and clustered computing nodes.
How does the PCIe 3.0 x8 interface affect the deployment of this network card? +
The PCIe 3.0 x8 interface ensures that the network adapter is not a bottleneck for your server’s internal bus. With ample bandwidth provided by the Gen3 lanes, the card can support full-duplex 10GbE traffic on both ports simultaneously without saturating the bus. It fits standard PCIe slots, making it easy to deploy in most modern enterprise server chassis.
Can this Mellanox card be used for virtualized server environments? +
It is an ideal choice for virtualized environments due to its support for advanced virtualization technologies, including SR-IOV. SR-IOV allows the NIC to present itself as multiple virtual functions, enabling virtual machines to access the network hardware directly. This significantly boosts throughput and reduces latency for virtualized applications compared to traditional software-based switching methods.
What power efficiency features are built into this ConnectX-3 adapter? +
Mellanox engineered this card with power efficiency in mind, optimizing its performance-to-watt ratio for enterprise use. By leveraging efficient silicon design and intelligent power management features, the card maintains stable operation while minimizing total energy consumption. This helps data centers manage their power budgets effectively, especially when deploying high densities of these cards across multiple server racks.
How can I obtain a bulk quote for multiple MCX312B-XCCT units? +
