CN1100E 10 Gigabit Network Card - Dual-Port SFP+ Adapter

The BK835A CN1100E adapter is a dual-port 10 GbE SFP+ Network Card designed for HPEProLiant servers, offering high-speed,wired network connection over optical or copper media. With two 10 GbE ports delivering up to 20 Gb/s total throughput, this card supports FCoE and iSCSI convergence×simplifying infrastructure for virtualised storage and networking. Its low-profile, PCIe 2.0 ×8 form factor ensures flexibility in diverse server chassis deployments and dense data center environments.This adapter is ideal for enterprise, virtualization, and SAN scenarios where performance, power efficiency, and simplified manageability are paramount×delivering enterprise-grade reliability and advanced acceleration for cloud and storage workloads.

Features

This PCI Express 2.0 ×8 plug-in card includes two SFP+ ports supporting up to 10 Gb/s each. Compatible with both direct attach copper cables and optical transceivers (e.g. SR modules), it offers flexible deployment across short and longer data center links. Built on the Emulex OneConnect architecture, it provides protocol offloads for TCP/IP, iSCSI, and Fibre Channel over Ethernet (FCoE), reducing server CPU load and enhancing throughput consistency

Advanced Options

The hardware offloading engine supports features like RSS, TSO, LSO, jumbo frames, VLAN tagging, NIC teaming, and PXE boot. In virtualised environments, it delivers support for VMware NetQueue and Microsoft VMQ to optimize host performance and scale
