Best Choice for Virtualization:
The explosive growth in virtualization is leading to an increasing demand for network performance. With more Virtual Machines (VMs) running on each multi-core server, networking traffic is dramatically increased with each VM competing for available I/O bandwidth. DW-599/X520 10g network card addresses networking bottlenecks in virtualized environments. These adapters enable network-intensive applications to achieve the performance expected in a virtualized environment.
The X520 10g Ethernet Lan Cards provides the best networking performance available in the industry, whether the physical port is configured in an emulation mode using the virtual switch in the Virtual Machine Monitor (VMM), or is directly assigned to a virtual machine. In the emulation mode, Intel’s I/O technology, Virtual Machine Device queues1 (VMDq) optimizes network performance by offloading data sorting and copying from the software Virtual Switch in the VMM to the Intel Ethernet 82599 10 Gigabit Controller. This configuration is best suited for a large number of VMs running standard applications that have limited bandwidth and latency requirements.
Unified Networking and Storage:The X520 10g Optical Network Card lowers your data center total cost of ownership (TCO) by providing the ability to route LAN and SAN traffic over a single fabric.
Support for FCoE:FCoE encapsulates Fiber Channel frames over standard Ethernet networks, enabling Fiber Channel to take advantage of 10 GbE networks while preserving its native protocol. The DW-599/X520 10g Optical Network Card offer FCoE hardware acceleration to provide performance comparable to FC HBAs. The server adapters support Data Center Bridging, also known as Converged Enhanced Ethernet (CEE), which allows customers to configure traffic classes and priorities to deliver a lossless Ethernet fabric. An Intel Ethernet X520 server adapter reduces TCO by eliminating redundant fabrics and saves the cost of expensive FC HBAs and FC switch ports.
Support for iSCSI:The server adapters provide complete support for proven native OS and VMM iSCSI initiators as well as iSCSI boot.
The X520 10g Optical Network Card do it all 10 Gigabit LAN, FCoE, and iSCSI; truly delivering on the promise of unified networking.
Reliable Performance:The X520 10g Optical Network Card include a number of advanced features that allow it to provide industry-leading performance and reliability.
Security Optimizations:The adapters support IPsec offload for Microsoft’s Network Access Protection (NAP), Active Directory, and future security capabilities in Windows* 7. An LR-LINK 10G lan card allows customers to run a secure network environment without sacrificing performance.
PCIe v2.0 (5 GT/s):PCIe v2.0(5GT/s) support enables customers to take full advan- tage of 10 GbE by providing a maximum of 20Gbps bi-directional throughput per port on a single dual port card.
Designed For Multi-core Processors:Support for technologies such as multiple queues, receive-side scaling, multiple MSI-X vectors, and Low Latency Interrupts allow the DW-599/X520 Optical Network Card to provide high-performance, 10 Gigabit connectivity in multi-core server blades. These technologies distribute network processing across multiple CPU cores, improving overall performance.
