Intel's X520 adapter is known for its high performance, low latency, reliability, and flexibility. The addition of the Intel Ethernet Server Bypass Adapter X520-SR2 delivers all of the 10GbE performance in addition to business continuity in the event of a network failure. The bypass capability removes a single point of failure so that essential business communication can continue while a system failure is diagnosed and resolved. In the event of a power, hardware, or software failure, bypass will automatically activate, allowing network traffic to continue.
The Intel Ethernet Server Bypass Adapter X520-SR2 is a dual-port 10GbE bypass adapter. This adapter is designed for 10 Gigabit performance and multi-core processors. PCIe v2.0 (5 GT/s) support enables customers to take full advantage of 10GbE by providing maximum of 20 Gbps bi-directional throughput per port on an individual dual-port card.
Data center networks are being pushed to their limits. The escalating deployments of servers with multi-core processors and demanding applications such as database clusters, cloud deployments, and video-on-demand are driving the need for 10 Gbps connections. Customers require flexible, dependable, and scalable I/O solutions to meet the rigorous requirements of running mission-critical applications. The Intel Ethernet Server Bypass Adapter addresses the demanding needs of the next-generation data center providing unmatched features and proven, reliable performance.
Intel Virtualization Technology for connectivity (Intel VT-c)
Intel Ethernet controller includes Intel Virtualization Technology for connectivity (Intel VT-c) to deliver virtualized I/O performance optimizations and Quality of Service (QoS) features designed directly into the controller's silicon. Working in conjunction with virtualization-optimized drivers in normal mode, PCI-SIG Single Root I/O Virtualization and Sharing (SR-IOV) can be used to help reduce I/O bottle-necks, and improve the overall server performance.
Hypervisor bypass using SR-IOV
In normal mode, bypassing the hypervisor and allowing direct hardware access by virtual machines, reduces CPU overhead, reduces latency, and increases network throughput. Most of the current hypervisor releases have been enabled to partition a single physical Ethernet controller in to multiple virtual Ethernet controllers that can be used directly by VMs by taking advantage the PCI-SIG SR-IOV standard. The use of these virtual controllers, known as Virtual Functions (VF), enables additional QoS features in the controller's silicon to manage and direct traffic such as traffic isolation, port partitioning with bandwidth allocation and on-chip VF-VF switching.
iSCSI accelerationProduct Highlights
In normal mode, this adapter provides complete support for proven native OS iSCSI initiators as well as iSCSI boot. Intel Ethernet server adapter includes hardware-based iSCSI acceleration features that do not require offoading to a proprietary TCP/IP stack. iSCSI acceleration uses large send offload, receive side coalescing and transmit send offloads to help reduce latency and lower CPU utilization.
