The IBM 2CC1 PCIe2 4-Port Adapter is a high-speed network interface card designed to meet the demands of modern data centers and enterprise networking environments. It features two 10 Gigabit Ethernet ports for Fiber Channel over Ethernet (FCoE) connections via SFP+ transceivers, and two 1 Gigabit Ethernet ports for traditional networking via RJ45 connectors. This versatile adapter allows for the convergence of data and storage networking, facilitating the delivery of high-bandwidth, low-latency network connectivity for servers and storage systems. By supporting FCoE, the IBM 2CC1 enables the reduction of network complexity and costs by consolidating data and storage traffic onto a single network infrastructure. The PCIe2 interface ensures compatibility with the latest server platforms and provides sufficient bandwidth to support the high-speed data transfers required by today's applications. The adapter's advanced features, such as hardware offloads for FCoE and TCP/IP processing, further enhance performance and relieve the host CPU from intensive networking tasks. The IBM 2CC1 adapter is an ideal solution for organizations looking to streamline their networking infrastructure while achieving superior performance and reliability.
