World-Class Performance
Virtualized Overlay Networks
Infrastructure as a Service (IaaS) cloud demands that data centers host and serve multiple tenants, each with their own isolated network domain over a shared network infrastructure. To achieve maximum efficiency, data center operators are creating overlay networks that carry traffic from individual Virtual Machines (VMs) in encapsulated formats such as Network Virtualization using Generic Routing Encapsulation (NVGRE) and Virtual Extensible Local Area Network (VXLAN) over a logical tunnel, thereby decoupling the workloads location from its network address.
Overlay Networks architecture introduces an additional layer of packet processing at the hypervisor level, adding and removing protocol headers for the encapsulated traffic. The new encapsulation prevents many of the traditional offloading capabilities (e.g. checksum, Time Sharing Option {TSO}) from being performed at the NIC.
 
LREC***1XF-SFP+ effectively addresses the increasing demand for an overlay network, enabling superior performance by introducing advanced NVGRE and VXLAN hardware offload engines that enable the traditional offloads to be performed on the encapsulated traffic.
With LREC***1XF-SFP+, data center operators can decouple the overlay network layer from the physical NIC performance, thus achieving native performance in the new network architecture.
 
I/O Virtualization
LREC***1XF-SFP+ SR-IOV technology provides dedicated adapter resources and guaranteed isolation and protection for virtual machines (VMs) within the server. I/O virtualization with ConnectX*3 Pro gives data center managers better server utilization while reducing cost, power, and cable complexity.
 
RDMA over Converged Ethernet (RoCE)
LREC***1XF-SFP+ utilizing IBTA RoCE technology delivers similar low-latency and high-performance over Ethernet networks. Leveraging Data Center Bridging capabilities, RoCE provides efficient low latency RDMA services over Layer 2 Ethernet. With link-level interoperability in existing Ethernet infrastructure, Network Administrators can leverage existing data center fabric management solutions.
 
Sockets Acceleration
Applications utilizing TCP/UDP/IP transport can achieve industry-leading throughput over *0GbE. The hardware-based stateless offload engines in LREC***1XF-SFP+ reduce the CPU overhead of IP packet transport. Socket acceleration software further increases performance for latency sensitive applications.
 
Storage Acceleration
A consolidated compute and storage network achieves significant cost-performance advantages over multi-fabric networks. Standard block and file access protocols can leverage Ethernet for high-performance storage access.
