OCm14102-U4-D Dual-port 10GbE Blade
Select Network Daughter Card (bNDC)
Emulex VNeX tunnel offload is powered by a multi-core adapter ASIC engine that accelerates
the performance of overlay networking. By offloading the Ethernet packet header
encapsulation process, while simultaneously preserving legacy stateless TCP offloads,
Emulex VNeX provides full native network performance with reduced server CPU utilization
in an overlay network environment, enabling greater VM density. It also results in increased
server power efficiency reducing data center energy and cooling expenses. Additionally, this
technology allows Dell customers to massively scale networks to meet the growing demands
of simultaneously servicing many user groups.
Optimized bandwidth allocation with support for new Dell NParEP
Dell has doubled the NIC partitioning bandwidth with the new Dell NParEP feature supported
on Emulex OCx1410x adapters. Dell PowerEdge 13th Generation servers, with Emulex
OCm14102-U4-D network adapters, offer customers the ability to configure up to 16 NIC
functions (partitions) per adapter, or up to eight NIC functions per port. Alternatively, up to
two of the functions (partitions) on each port can be configured with one ISCSI and one FCoE
storage function. NParEP is ideal for virtualized server environments because bandwidth
allocation can be optimized to support I/O intensive applications, virtualization services and
server management functions.
Flexible storage connectivity using concurrent FCoE and iSCSI hardware offloads
OCm14102-U4-D supports FCoE offload, using the same field-proven Emulex drivers that
work with Emulex LightPulse® Fibre Channel Host Bus Adapters (HBAs). OCm14102-U4-D also
supports hardware iSCSI offload, running storage traffic over a DCB Ethernet fabric, delivering
performance that is superior to iSCSI solutions based on software initiators and standard NICs.
OCm14102-U4-D has concurrent mode support, providing Dell customers with the ability to
support NIC, iSCSI and FCoE offloads on the same physical port with Dell NParEP technology.
Optimized host server virtualization density using SR-IOV
SR-IOV provides a more cost-effective solution than multiple physical adapter ports by
optimizing I/O for VMs, enabling higher host server virtualization ratios to deliver maximum
server return on investment (ROI). SR-IOV enables multiple VMs to directly access the
OCm14102-U4-D’s I/O resources, thus allowing the VM’s network I/O to bypass the hypervisor’s
virtual switch 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, lower CPU
utilization and significantly reduced latency as compared to the alternative of software-
emulated NIC devices that are implemented in the hypervisor.
Simplified management using the Dell iDRAC8 framework
or Emulex OneCommand® Manager application
The Dell OCm14102-U4-D supports both Dell and Emulex management tools, and is fully
integrated with Dell’s Lifecycle Controller management scheme. Dell Lifecycle Controller
provides fast, efficient, secure local and remote deployment, configuration and update
capabilities. The Emulex OneCommand Manager application provides centralized management
of Dell adapters based on 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, enabling ’single
window pane’ management for VMware deployments.
Enterprise-class performance and reliability
Leveraging four generations of advanced, field-proven controller and adapter technology,
the Dell OCm14102-U4-D meets the robust interoperability and reliability requirements of
enterprise cloud and scale-out data centers.
