OCM14000-OCP Datasheet, PDF (2/4 Pages) List of Unclassifed Manufacturers – Data acceleration with RoCE support

OCm14000-OCP 10GbE
Ethernet Network Adapters
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.
Emulex VNeX offload technology powered by a multi-core 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
Emulex 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
Emulex 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 and 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.
