Frequently Asked Questions
What are the primary performance specifications of the Mellanox ConnectX-5 MCX515A-CCAT? +
The MCX515A-CCAT is a high-performance 100GbE single-port adapter utilizing the QSFP28 form factor. It leverages a PCIe 3.0 x16 host interface, ensuring low-latency data transfers and high throughput for data-intensive enterprise applications. This card is designed to offload CPU-intensive tasks, optimizing overall server efficiency in high-speed networking environments.
Is the MCX515A-CCAT compatible with standard PCIe slots in modern servers? +
Yes, this card features a PCIe 3.0 x16 interface and comes with a tall bracket, making it ideal for standard 2U or larger rackmount servers. Ensure your server chassis supports the full-height bracket and that you have an available x16 physical slot to accommodate the bandwidth requirements for 100GbE operations.
What type of optical transceivers or cables does the MCX515A-CCAT support? +
As a QSFP28 interface card, the MCX515A-CCAT supports a variety of 100GbE connectivity options. You can utilize 100G QSFP28 optical transceivers for long-reach fiber deployments, or opt for Direct Attach Copper (DAC) cables and Active Optical Cables (AOC) for short-reach, high-speed connectivity within the data center rack.
How does the ConnectX-5 architecture improve virtualization performance? +
The ConnectX-5 architecture features advanced hardware offloads for virtualization, including SR-IOV and OVS offload capabilities. These features allow the card to handle packet processing directly, significantly reducing CPU overhead and latency for virtual machines, making it an excellent choice for cloud infrastructures and high-density virtualization platforms.
Does this NIC support RoCE for high-performance computing? +
The MCX515A-CCAT supports RDMA over Converged Ethernet (RoCE), which is essential for low-latency networking in storage and HPC environments. By enabling direct memory access between servers, RoCE offloads data movement tasks from the host processor, resulting in faster application response times and higher efficiency for clustered computing workloads.
What is the physical bracket configuration for this specific Mellanox SKU? +
This specific SKU, the MCX515A-CCAT-VHBRSN, is shipped with a pre-installed tall bracket (full-height). It is engineered for standard server slots that require the full height dimensions. If your deployment environment consists of low-profile or 1U half-height servers, you will need to ensure your chassis is compatible with this form factor before installation.
Can I use the MCX515A-CCAT for network storage applications? +
Absolutely. This adapter is highly effective for NVMe-over-Fabrics (NVMe-oF) and other storage-intensive networking tasks. Its high 100GbE throughput combined with low-latency hardware offloads ensures that storage arrays connected via Ethernet perform with the speed and reliability required for enterprise-grade flash storage systems.
How does the ConnectX-5 handle packet processing compared to standard NICs? +
Unlike standard NICs, the ConnectX-5 utilizes specialized on-board hardware engines to handle traffic shaping, packet header inspection, and complex offloads. This offloading capability frees up system CPU cycles, allowing your applications to utilize more computational resources while maintaining line-rate performance at 100GbE speeds, even during peak traffic periods.
How can I request a bulk quote for multiple Mellanox ConnectX-5 cards? +
