The Intel 10 Gigabit CX4 Dual Port Server Adapter from Rorke Data offers the lowest cost per port of all the current 10 GbE interconnects. The low-profile PCI express form factor combined with two CX4 ports and a low-power envelope for energy efficiency, makes the board ideal for slot-constrained environments. The 10 GBASE-CX4 Adapter is well-suited for shorter distance and low latency requirements.
The CX4 Dual Port Server Adapter provides bandwidth-intensive applications with highly affordable 10 GbE network performance for distances up to 49.2' (15 m) with standard twin axial or up to 328' (100 m) with Intel connects cable. When implemented within multi-core processor environments, the CX4 Adapter offers advanced networking features for efficient distribution of Ethernet workloads across CPU cores.
The Virtual Machine Device queue* (VMDq) technology offloads data sorting and data copying from the virtual machine monitor (VMM) software layer to the hardware, improving overall throughput and CPU utilization on virtualized servers.
The CX4 Dual Port Server Adapter supports iSCSI acceleration through Intel I/OAT and provides advanced features for unified storage connectivity.
Next-Generation 10 Gigabit Performance
10 Gigabit Ethernet has moved past the early adoption stage and is rapidly becoming mainstay for backbones within enterprise and service provider networks. The escalating deployments of servers with multi-core processors and demanding applications such as High Performance Computing (HPC), database clusters and video on demand are driving the need for 10 Gigabit connections. Designed to meet the need of high-speed, low-latency interconnects of HPC clusters, the CX4 Dual Port Server Adapter provides bandwidth-intensive applications with highly affordable 10 GbE network performance for distances up to 49.2' (15 m) with standard twin axial or up to 328' (100 m) with Intel connects cable. Based on the Intel 82598EB 10 Gigabit Ethernet Controller, the CX4 Dual Port Server Adapter is designed to meet the throughput requirements of bandwidth-hungry applications. It can also be used in wiring closets and server racks, as well as data centers to aggregate servers.
When implemented within multi-core processor environments, the CX4 Dual Port Server Adapter offers advanced networking features for efficient distribution of Ethernet workloads across CPU cores. Load balancing of interrupts using MSI-X enables more efficient response times and improved application performance. CPU utilization can be lowered further through stateless offloads such as TCP segmentation offload, header replications/splitting, and Direct Cache Access (DCA).
Multiple Queues Optimized for Virtual Environments
The CX4 Dual Port Server Adapter is optimized for virtualized environments, supporting multiple queues and alleviating I/O bottlenecks between virtual machines. The VMDq* technology offloads data sorting and data copying from the virtual machine monitor (VMM) software layer to the hardware, improving overall throughput and CPU utilization on virtualized servers. Additionally, the Dual Port Server Adapter enables I/O Acceleration Technology2 (Intel I/OAT) with support for QuickData for faster I/O processing on the new quad-core and dual-core Intel Xeon processor-based servers.
*Intel VMDq requires an operating system that supports VMDq
Advances for Unified Storage
The fast growth in storage capacity coupled with server virtualization has brought the need for Storage Area Network (SAN) to the forefront. To satisfy this growing demand, the CX4 Server Adapter supports iSCSI acceleration through Intel I/OAT and provides advanced features for unified storage connectivity. Fast and reliable networked storage can be achieved via native iSCSI support with Microsoft, Linux and VMware operating systems as well as support for iSCSI remote boot.
Direct Cache Access (DCA)
The I/O device activates a pre-fetch engine in the CPU that loads the data into the CPU cache ahead of time, before use, eliminating cache misses and reducing CPU load.
Intel 82598EB 10 Gigabit Ethernet Controller
Industry-leading, energy-efficient design for next-generation 10 Gigabit performance and multi-core processors.
Enables higher bandwidth and throughput from standard and low-profile PCIe slots and servers.
Load Balancing on Multiple CPUs
Increases performance on multi-processor systems by efficiently balancing network loads across CPU cores when used with Receive-Side Scaling from Microsoft or Scalable I/O on Linux.
Accelerates I/O with higher throughput and lower CPU utilization by offloading processing overhead.
