The IBM EC29 is a low-profile, PCIe Generation 2 interface card that provides two ports of 10 Gigabit Ethernet connectivity. Specifically designed for use in high-performance computing and data center environments, it supports the RoCE (RDMA over Converged Ethernet) standard, allowing for high efficiency, low latency data transfers over Ethernet networks. The SR (short reach) designation indicates its suitability for connections within the same data center. Its compact, low-profile form factor makes it an ideal choice for servers where space is at a premium. Enhanced with advanced features such as hardware offloads for network virtualization, QoS for traffic prioritization, and energy-efficient Ethernet, the EC29 is designed to deliver superior performance, reliability, and power efficiency, making it suitable for a wide range of applications including cloud computing, storage networking, and enterprise data networking.
