IBM 4662-ALBM – 25/10 GbE (RoCE) 2 Port Adapter Cards (Pair)

Detailed Description:

The IBM 4662-ALBM represents a pair of high-performance Ethernet adapter cards, each providing two ports capable of 25GbE or 10GbE connectivity. These adapters are specifically designed to support RDMA over Converged Ethernet (RoCE), a network protocol that allows remote direct memory access (RDMA) over an Ethernet network. This capability significantly enhances data transfer efficiency and reduces latency, making these adapters ideal for high-performance computing (HPC), storage networking, and data center applications.

By leveraging RoCE technology, the IBM 4662-ALBM adapters enable more efficient data transfers between servers and storage systems, minimizing CPU overhead and improving overall system performance. The dual-port configuration provides added flexibility and redundancy, ensuring continuous operation and high availability of network services. Additionally, these adapters support advanced networking features such as virtualization, traffic prioritization (QoS), and network partitioning (NPAR), providing a scalable and versatile solution for modern IT infrastructure.
