OCm14102-UX-OCP Converged Network Adapter

OneConnect 10GbE Open Compute Project Mezzanine Card

Currently Viewing:

The OneConnect® OCm14000-OCP 10Gb Ethernet (10GbE) Converged Network Adapter (CNA) provides high performance 10GbE connectivity in an Open Compute Project (OCP) mezzanine card form factor.

The OCm14000-OCP adapter enables:

  • Increased data center IT agility and scalability through deployment of a secure multi-tenant cloud
  • Optimized server hardware utilization, by scaling high density virtualization
  • User-controlled bandwidth partitioning delivered across workloads and management services

The OCm14000-OCP CNA is designed for the high bandwidth and scalability demands of enterprise applications, more scalable virtualization with support for enhanced Single Root I/O Virtualization (SR-IOV) and Network Interface Card (NIC) 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 from 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 (TCO), energy efficiency, and reduced complexity in the scalable computing space. The OCm14000-OCP adapter adheres to the mezzanine card specification for OCP v2.0 motherboards.

Emulex 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 networking 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.

Emulex 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 adapter leverages RDMA* over Converged Ethernet (ROCE), enabling server-to-server data movement directly between application memory, without any CPU involvement; thus providing high throughput and data acceleration on a standard Ethernet fabric, without the need for any specialized infrastructure or management.

Flexible workload storage connectivity with FCoE and iSCSI offloads
The OCm14000-OCP adapter supports FCoE offload, using the same enterprise-class Emulex drivers that work with Emulex LightPulse® Fibre Channel (FC) Host Bus Adapters (HBAs). The OCm14000-OCP adapter also supports iSCSI offload, providing performance that is superior to iSCSI solutions, based on software initiators and standard NICs. Finally, the OCm14000-OCP adapter also has the ability to support NIC and iSCSI or Fibre Channel over Ethernet (FCoE) offloads on the same port.

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 return on investment (ROI). SR-IOV provides a more cost-effective solution than multiple, physical adapter ports. SR-IOV enables multiple VMs to directly access the OCm14000–OCP adapter’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 (also known as NIC partitioning or NPAR)
Emulex Universal Multi-Channel (UMC) is ideal for virtualized server environments because bandwidth allocation can be optimized to support VM migration, management, and I/O-intensive applications. UMC allows multiple Peripheral Component Interconnect (PCI) physical functions (PFs) to be created on each adapter port. As a CNA, each adapter can be configured with up to 16 functions.

The key benefits of deploying Emulex UMC technology include:

  • Lower TCO
  • Consolidates multiple 1GbE adapters, associated cables, and switch ports
  • Higher VM workload bandwidth allocation to drive higher VM density on host servers
  • Lower per-Gb bandwidth cost compared to deploying multiple 1GbE adapters

Optimized I/O utilization

  • Granular bandwidth provisioning minimizes wasted idle bandwidth and waste of dedicated 1GbE adapters
  • Enables Service Level Agreement (SLA)-based provisioning and deployment

Simplified deployment

  • UMC is not dependent on specialized OS support
  • Works with any 10GbE switch

UMC is ideal for virtualized server environments because bandwidth allocation can be optimized to support I/O-intensive applications, VM migration, and management functions.

Simplified management: OneCommand® Manager application
The OneCommand Manager application provides centralized management of Emulex OneConnect CNAs and LightPulse 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.
