PCIe2 LP 2-Port 10GbE RoCE SFP+ Adapter (FC EL27; CCIN EC27)

Learn about the specifications and operating system requirements for the feature code (FC) EL27 adapters.

Overview

The FC EL27 PCIe2 LP 2-Port 10GbE RoCE SFP+ adapter is a low-profile adapter equivalent to the FC EC27.

The adapter is a PCIe generation-2 (PCIe2), dual port, 10-Gigabit Ethernet (GbE) adapter with a PCIe 2.0 host bus interface. The adapter delivers high-bandwidth and low-latency 10 GbE connectivity. The adapter is optimized for high-transaction databases, cloud computing, virtualization, storage, and other data center applications. The adapter improves network performance by increasing available bandwidth to the central processing unit (CPU) and providing enhanced performance. The two 10 Gb small form-factor pluggable (SFP+) transceiver ports are used for connectivity with other servers or switches in the network. Each SFP+ port provides Ethernet connectivity with a nominal data rate of 10 gigabits per second (Gbps), and uses the SFP+ copper twinaxial cables up to 5 m (16.4 ft) in length. The link aggregation and failover features of the adapter are ideal for critical network applications that require redundancy and high availability.
