High Performance Networking for Enterprise Virtualization and the Cloud
The OneConnect® OCm14000-OCP 10Gb Ethernet (10GbE) Network Adapters provide high performance 10GbE connectivity in an Open Compute Project (OCP) mezzanine form factor.

The OCm14000-OCP adapters enable:

  • Increased data center IT agility and scalability through deployment of a secure multitenant cloud
  • Optimized server hardware utilization by scaling high density virtualization
  • Deliver user-controlled bandwidth partitioning across workloads and management services

The OCm14000-OCP adapters are designed for the high bandwidth and scalability demands of enterprise applications, more scalable virtualization with support for RDMA* over Converged Ethernet (RoCE*) fabric, enhanced Single Root I/O Virtualization (SR-IOV) and Network Interface Card (NIC) port partitioning, and next generation overlay network technologies that address the need for virtual machine (VM) mobility and massive scaling of Layer 2 subnets inside private or hybrid cloud infrastructures.

The Open Compute Project Foundation is a rapidly growing community of engineers around the world whose mission is to design and enable the delivery of the most efficient server, storage and data center hardware designs for scalable computing. The OCP designs are maximized for total cost of ownership, energy efficiency and reduced complexity in the scalable computing space. The OCm14000-OCP adapters adhere to the mezzanine card specification for OCP v2.0 motherboards.

Virtual Network Exceleration (VNeX™) Overlay Network Offloads for Multi-Tenant Cloud Networking
Scaling existing technologies for private or public multi-tenant infrastructures requires networking solutions that can enable VM-to-VM communication and virtual workload migration across Layer 2 and Layer 3 boundaries without impacting connectivity or performance.

At the same time, these solutions need to ensure isolation and security for thousands or millions of tenant networks. However, with existing technology, the available 4094 Virtual Local Area Network (VLAN) IDs are insufficient to isolate/secure each tenant in a data center (private cloud) or hybrid cloud environment.

Virtual Extensible Local Area Network (VXLAN), supported by VMware and Linux, and Network Virtualization using Generic Routing Encapsulation (NVGRE), supported by Microsoft, are two next generation overlay network solutions that address these requirements. These solutions are a frame-in-frame data packet encapsulation scheme enabling the creation of virtualized Layer 2 subnets that can span physical Layer 3 IP networks. Traffic from each VM is mapped to a specific virtual network; the packets are then routed transparently over the existing physical infrastructure.

VNeX offload technology powered by a multicore adapter ASIC engine accelerates the performance of network virtualization by offloading the header encapsulation process, while simultaneously preserving legacy stateless TCP offloads, providing full native network performance in a virtual network environment.

Remote Direct Memory Access (RDMA*) Support
The OCm14000-OCP adapters leverage RoCE* enabling server to server data movement directly between application memory without any CPU involvement providing high throughput and data acceleration on a standard Ethernet fabric without the need for any specialized infrastructure or management.

Optimized Host Virtualization Density with SR-IOV Support
SR-IOV optimizes I/O for VMs, enabling higher host server virtualization ratios to deliver maximum server ROI. SR-IOV provides a more cost-effective solution than multiple, physical adapter ports. SR-IOV enables multiple VMs to directly access the OCm14000’s I/O resources, thus allowing VM networking I/O to bypass the host and take a path directly between the VM and the adapter, eliminating redundant I/O processing in the hypervisor. This, in turn, allows higher I/O performance and lower CPU utilization as compared to the alternative of software-emulated NIC devices that are implemented in the hypervisor.

Optimized Bandwidth Allocation with Emulex Universal Multi-Channel Port Partitioning
Universal Multi-Channel (UMC) is ideal for virtualized server environments because bandwidth allocation can be optimized to support virtual machine migration, management and I/O intensive applications. UMC allows multiple Peripheral Component Interconnect (PCI) physical functions to be created on each adapter port. Each port on the OCm14000 can be configured with up to eight functions.

Simplified Management Emulex OneCommand Manager Application
The OneCommand Manager provides centralized management of Emulex OneConnect Converged Network Adapters (CNAs) and LightPulse® Fibre Channel Host Bus Adapters (HBAs) throughout the data center from a single management console. The OneCommand Manager application provides a graphical user interface (GUI) and a scriptable command line user interface (CLI). OneCommand Manager for VMware is fully integrated with VMware vCenter to simplify management for virtual server deployments.

Fourth Generation Platform Delivers Enterprise-Class Reliability & Performance
Leveraging generations of advanced, field-proven controller and adapter technology, OCm14000-OCP adapters meet the robust interoperability and reliability requirements of enterprise and scale-out data centers.
