Mellanox ConnectX-3 EN Gigabit Ethernet Media Access Controller (MAC) with PCI Express 3.0 delivers high-bandwidth and industry-leading Ethernet connectivity for performance-driven server and storage applications in enterprise data centers, high-performance computing, and embedded environments.
Clustered databases, web infrastructure, and high frequency trading are just a few applications that will achieve significant throughput and latency improvements resulting in faster access, real-time response and more users per server. ConnectX-3 EN improves network performance by increasing available bandwidth while decreasing the associated transport load on the CPU especially in virtualized server environments.
ConnectX-3 is well suited for blade server and LAN on Motherboard (LOM) designs. Its integrated PHYs, and minimal additional external component requirements were designed for a small PCB footprint. It also has an array of power saving features with real-time monitors that lower total system power usage.
World-class Ethernet performance
RDMA over Converged Ethernet - ConnectX-3 utilizing IBTA RoCE technology provides efficient RDMA services, delivering low-latency and high-performance to bandwidth and latency sensitive applications. 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 10 or 40 GbE. The hardware-based stateless offload and flow steering engines in ConnectX-3 reduce the CPU overhead of IP packet transport, freeing more processor cycles to work on the application.
ConnectX-3 EN with Virtual Intelligent Queuing (Virtual-IQ) technology provides dedicated adapter resources and guaranteed isolation and protection for virtual machines (VM) within the server. ConnectX-3 EN gives data center managers better server utilization and LAN and SAN unification while reducing costs, power, and complexity.
Precision data centers
ConnectX-3 EN 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.
A consolidated compute and storage network achieves significant cost-performance advantages over multi-fabric networks. Standard block and file access protocols can leverage RDMA for high-performance storage access. T11 compliant encapsulation (FCoE) with full hardware offloads simplifies the storage network while keeping existing Fiber Channel targets.
Quality of ServiceProduct Highlights
Resource allocation per application or per VM is provided and protected by the advanced QoS supported by ConnectX-3 EN. Service levels for multiple traffic types can be based on IETF DiffServ or IEEE 802.1 p/Q allowing system administrators to prioritize traffic by application, virtual machine, or protocol. This powerful combination of QoS and prioritization provides the ultimate fine-grained control of traffic - ensuring that applications run smoothly in today's complex environments.
