Description

Description:

The LR-LINK LREC9701EF-SFP PCIe Single-Port Server Adapter Is PCIe GbE network adapters. Built with the Intel 82576 Gigabit Ethernet Controller, these new adapters showcase the next evolution in GbE networking features for the enterprise network and data center. These features include support for multi-core processors and optimization for server virtualization.

Designed for Multi-Core Processors

These single-port adapter provide high-performing, single- port Gigabit connectivity in a multi-core platform as well as In a virtualized environment. In a multi-core platform, the adapters support different technologies such as multiple queues,  receive-side  scaling,   MSI-X,  and  Low  Latency Interrupts, that help in accelerating the data across the platform, thereby Improving application response times, The I/O technologies on a multi-core platform make use of the multiple queues and multiple Interrupt vectors available on the network controller. These queues and interrupt vectors help in load balancing the data and interrupts amongst themselves in order to lower the load on the processors and improve overall system performance. For example, depending upon the latency sensitivity of the data, the low level latency interrupts feature can bypass the time interval for specific TCP ports or for flagged packets to give certain types of data streams the least amount of latency to the application.

Optimized for Virtualization

The LR-LINK LREC9701EF-SFP Single-Port Server Adapter showcase the latest virtualization technology called Intel Virtualization Technology for Connectivity (IntelVTfor Connectivity).IntelVT for Connectivity is a suite of hardware assists that improve overall system performance by lowering the I/O overhead in a virtualized environment. This optimizes CPU usage, reduces system latency, and improves I/O through-  put.IntelVT for Connectivity
includes:
Virtual Machine Device Queues (VMDq)
Intel I/O Acceleration Technology
Use of multi-port adapters in a virtualized environment is very important because of the need to provide redundancy and data connectivity for the applications/workloads in the virtual machines, Due to slot limitations and the need for redundancy and data connectivity, it is recommended that a virtualized physical server needs at least six GbE
ports to satisfy the I/O requirement demands.
Virtual Machine Device queues (VMDq)
VMDq reduces I/O overhead created by the hypervisor in a virtualized server by performing data sorting and coalescing in the network silicon.2 VMDq technology makes use of multiple queues in the network controller. As data packets enter the network adapter, they are sorted, and packets traveling to the same destination (or virtual machine) get grouped together in a single queue. The packets are then sent to the hypervisor, which directs them to their respective virtual machines. Relieving the hypervisor of packet filtering and sorting improves overall CPU usage and throughput levels.
