The Mellanox MCX621102AN-ADAT is a high-performance dual-port 25GbE network adapter from the ConnectX-6 Dx EN series. Designed for next-generation enterprise, cloud, and storage applications, this card delivers exceptional performance, advanced offload capabilities, and efficient data handling. Featuring a PCIe 4.0 x8 interface, dual SFP28 ports, and No-Crypto variant for environments not requiring hardware security offloads, this NIC is ideal for high-throughput, low-latency deployments.
25GbE Dual-Port SFP28
High-speed dual SFP28 connectivity offering 25 Gigabit Ethernet per port, enabling up to 50Gbps aggregate throughput.
PCIe Gen 4.0 x8 Interface
Utilizes the latest PCI Express Gen 4.0 technology for faster data movement and reduced bottlenecks.
ConnectX-6 Dx Silicon
Based on Mellanox's advanced network controller offering enhanced performance, virtualization, and storage acceleration.
No Crypto Variant
Streamlined version without onboard IPsec or TLS crypto acceleration-ideal for environments where security is managed externally.
Full Height (Tall) Bracket
Standard form factor for compatibility with a wide range of server chassis.
