XE4310R is a single-chip, dual-port 10 Gigabit Ethernet (10GbE) Ethernet Controller targeting enterprise applications requiring 10 Gigabit (10Gb) wire-speed performance, multi-protocol offload capabilities and advanced I/O virtualization. The XE4310R controller has two 10Gb Ethernet (10GbE) interfaces that support XAUI, CX-4, KR and KX-4 physical interfaces, and an x8 PCI-Express Gen2 host bus interface. Dual 10GbE network ports can be configured as active/active or active/passive modes of operation. XE4310R also supports quad-port GbE and a mix of dual-port 10GbE and 1GbE.

The XE4310R controller is built around an array of eight programmable packet engines (PEs), plus an additional ARM9 processor. By offloading TCP/IP, Fibre Channel over Ethernet (FCoE) and iSCSI protocol processing from the host CPU to dedicated PEs, XE4310R delivers a highly integrated, low power, high performance 10GbE solution ideal for accelerating network and storage application performance on servers and storage systems.

I/O virtualization technology is a key technology for XE4310R controllers, allowing network and storage resources to be carved up into multiple hardware-isolated and protected virtual network and virtual storage interfaces. Virtual network and virtual storage interfaces can be assigned to virtual machines (VMs) to realize near-native performance. Fine-grain Quality of Service (QoS) management features allow precise bandwidth allocation and management for individual virtual network and storage interfaces through centralized policies using industry-standard management APIs. XE4310R addresses the need for advanced enterprise class I/O virtualization with driver support for VMware ESX, Linux KVM, Xen and Microsoft Hyper-V hypervisors.

XE4310R controllers are a key component of the Emulex OneConnect® Universal Converged Network Adapter (UCNA) product line that provides10 GbE server connectivity for networking and storage with high performance protocol offloads for TCP/IP, TCP Chimney Offload Engine (TOE), iSCSI and FCoE.
