Broadcom Inc. XE4310R 10Gb Ethernet Controller XE4310R

XE4310R is a single chip, dual-port 10Gb Ethernet (10GbE) controller targeting enterprise applications requiring 10Gb wire-speed performance, multi-protocol offload capabilities and advanced I/O virtualization. The XE4310R Controller has two 10GbE interfaces that support XAUI, CX-4, KR and KX-4 physical interfaces, and an x8 PCI Express (PCIe) 2.0 host bus interface. Dual 10GbE network ports can be configured as active/active or active/passive modes of operation. XE4310R also supports quad-port 1GbE 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® family of Network Adapters that provide 10GbE server connectivity for networking and storage with high performance protocol offloads for TCP/IP, TCP Chimney Offload Engine (TOE), iSCSI and FCoE. Key Features Dual 10Gb MAC and dual XAUI/10GBASE-CX4/10G BASE-KX4/10GBASE-KR interfaces Full hardware-based TCP/IP offload including fragmentation, reassembly and out-of-order processing to minimize host CPU utilization and maximize multi-core applications processing Complete FCoE offload based on 10 generations of field-proven Emulex LightPulse® Fibre Channel adapters Complete iSCSI offload including header and data digests, supported by third-generation iSCSI software Large on-chip buffers, assisted by innovative cache architecture, maximizes performance and reduces the number of external components and memories required Voltage controlled oscillator (VCO) technology for improved signal integrity and reliability Target Applications Blade servers Enterprise servers Web servers High performance clustered servers Network Attached Storage (NAS) iSCSI target controllers
