ConnectX-3 adapter cards with Virtual Protocol Interconnect (VPI) supporting InfiniBand and Ethernet connectivity provide the highest performing and most flexible interconnect solution for PCI Express Gen3 servers used in enterprise data centers, high-performance computing, and embedded environments.
ConnectX-3 delivers low latency, high bandwidth, and computing efficiency for performance-driven server and storage clustering applications. Efficient computing is achieved by offloading from the CPU protocol processing and data movement overhead such as RDMA and send/receive semantics allowing more processor power for the application. CORE-Direct brings the next level of performance improvement by offloading application overhead such as data broadcasting and gathering as well as global synchronization communication routines. GPU communication acceleration provides additional efficiencies by eliminating unnecessary internal data copies to significantly reduce application run time. ConnectX-3 advanced acceleration technology enables higher cluster efficiency and large scalability to tens of thousands of nodes.
RDMA over converged Ethernet
ConnectX-3 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.
Applications utilizing TCP/UDP/IP transport can achieve industry leading throughput over InfiniBand or 10 or 40GbE. The hardware-based stateless offload engines in ConnectX-3 reduce the CPU overhead of IP packet transport. Sockets acceleration software further increases performance for latency sensitive applications.
ConnectX-3 Virtual Intelligent Queuing (Virtual-IQ) with SR-IOV technology provides dedicated adapter resources and guaranteed isolation and protection for virtual machines (VM) within the server. I/O virtualization with ConnectX-3 gives data center managers better server utilization while reducing cost, power, and cable complexity.
Precision data centers
ConnectX-3 IEEE 1588 precision time protocol circuitry synchronizes the host clock to the data center master clock for accurate data delivery time stamping and data center SLA measurements. The hardware-based mechanisms ensure high accuracy and low jitter.
Storage acceleratedProduct Highlights
A consolidated compute and storage network achieves significant cost-performance advantages over multi-fabric networks. Standard block and file access protocols can leverage InfiniBand RDMA for high-performance storage access. T11 compliant encapsulation (FCoIB or FCoE) with full hardware offloads simplifies the storage network while keeping existing Fiber Channel targets.
