Designed for Multi-Core Processors
Support for iSCSI
Optimized for Virtualization
The LR-LINK LREC9042PF-2SFP Adapter showcases a suite of hardware assists that improves overall system performance by lowering the I/O overhead in a virtualized environment. This optimizes CPU usage, reduces system latency, and improves I/O throughput. These features include:
• Virtual Machine Device Queues (VMDq)
• Intel I/O Acceleration Technology (Intel I/OAT)
Virtual Machine Device queues (VMDq)
VMDq reduces I/O overhead on the hyper visor in a virtualized server by performing data sorting and coalescing in the network silicon. 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 hyper visor, which directs them to their respective virtual machines. Relieving the hyper visor of packet filtering and sorting improves overall CPU usage and throughput levels.
Reliable Performance
The adapter includes a number of advanced features that enable it to provide industry-leading quad-port 1GbE performance and reliability.
PCIe* v2.0 (5GT/s)
PCIe v2.0(5GT/s) support enables customers to take full advantage of the 100Mbps by providing a maximum of 2.0 Gbps bidirectional throughput per port on a single quad-port card.
For today’s demanding virtualized data center environments, the new LR-LINK LREC9042PF-2SFP Adapter delivers ultimate flexibility and scalability.
