Similar to the FUJITSU S26361-F3067-E21, the S26361-F3953-L210, also marketed as PLAN EM X557-T2, is an Open Compute Project (OCP) compatible network adapter designed to deliver robust and high-speed network connectivity. Featuring two 10GBASE-T Ethernet ports, this adapter enables high-speed data transfers over standard twisted-pair copper cabling, supporting distances up to 100 meters. Such capabilities make it suitable for a wide array of applications, including cloud deployments, high-performance computing environments, and data-heavy storage applications. The X557-T2 incorporates state-of-the-art power efficiency technologies and advanced networking features like Quality of Service (QoS), virtual LAN (VLAN) tagging, and virtual machine device queues (VMDq) for optimized data flow and reduced server load, ensuring both operational efficiency and environmental sustainability. Its OCP specification compliance ensures that it integrates seamlessly into OCP-certified systems, making it a versatile choice for modern data centers looking to leverage the benefits of open hardware standards.
