PCIe3 2-Port 40 GbE NIC RoCE QSFP+ Adapter (FC EC3B; CCIN 57BD)
Learn about the specifications and operating system requirements for the feature code (FC) EC3B adapter.
Overview
The PCIe3 2-Port 40 GbE NIC RoCE QSFP+ Adapter is a regular-height, PCIe generation-3 (PCIe3), dual
port, 40-Gigabit Ethernet (GbE) adapter with a PCIe 3.0 host bus interface. The adapter acts as a network
interface controller (NIC) and uses the IBTA RDMA over Converged Ethernet (RoCE) protocols to provide
efficient Remote Direct Memory Access (RDMA) services. The adapter delivers high-bandwidth and
low-latency 40 GbE connectivity, reducing the load on the processor and efficiently using the memory
access. This action off-loads the processor from networking tasks which improves the performance and
scalability of the processor.
The adapter is optimized for enterprise data centers, high-performance computing, transaction databases,
cloud computing, virtualization, storage, and other embedded environments. The adapter improves
network performance by increasing available bandwidth to the processor and by providing enhanced
performance. The adapter provides dedicated adapter resources and protection for virtual machines (VM).
The link aggregation and failover features of the adapter are ideal for critical network applications that
require redundancy and high availability.
The two 40 Gb quad (4-channel) small form-factor pluggable (QSFP+) transceiver ports are used for
connectivity with other servers or switches in the network. Each QSFP+ port provides Ethernet
connectivity with a nominal data rate of 40 gigabits per second (Gbps).
