QNAP QXG-25G2SF-CX6 Dual-Port 25GbE Network Card

Advanced Networking for Virtualization and Data Centers Elevate Your Network with QXG-25G2SF-CX6 The QNAP QXG-25G2SF-CX6 is a high-performance network expansion card featuring the NVIDIA Mellanox® ConnectX®-6 Lx SmartNIC controller. It supports PCIe Gen4 (backward compatible with Gen3/Gen2) and offers up to 25 Gbps transfer speeds. This card is ideal for I/O-intensive and latency-sensitive applications in virtualization environments and data centers. Key Features High-Speed 25GbE Networking Delivers up to 25 Gbps transfer speeds, supporting 10/25Gbps for fast and efficient networking. Port Trunking for Enhanced Bandwidth Combines multiple ports to achieve up to 50GbE, accelerating file sharing and intensive data transfer. SR-IOV Support for Virtualization Allocates bandwidth resources directly to VMs, ensuring reliable applications and reduced CPU overheads. RoCE Support for VMware® Virtualization Enables direct network access in RAM, reducing latency and enhancing performance in VMware® environments. Forward Error Correction (FEC) for Reliable Data Transfer Supports FEC to overcome packet loss in fast, long-distance networks, ensuring reliable data transmission. Broad Compatibility Compatible with specific QNAP NAS models, Windows® 10, Windows Server®, and Linux® (driver required), making it versatile for various system applications. FEC Modes for Different Network Needs NO FEC: Lowest latency, ideal for shortest distances. BASE-R FEC (Firecode): Approximately 80ns latency, suitable for middle distances. RS-FEC (Reed Solomon): Approximately 260ns latency, best for the longest distances. Notes for Optimal Setup FEC Mode Compatibility: Ensure both the source and receiver use the same FEC mode. Switch Compatibility: Check if your switch's firmware supports FEC. If not, disable the FEC function on the NIC through the NAS or computer operating system. Summary The QNAP QXG-25G2SF-CX6 network expansion card is a powerful solution for enhancing network performance in virtualization environments and data centers. Its combination of high-speed connectivity, SR-IOV, RoCE support, and FEC makes it an ideal choice for demanding network environments, ensuring fast, efficient, and reliable data transfer. Magbasa pa
