OCm14102-U4-D Dual-port
10GbE Blade Select Network
Daughter Card (bNDC)
For Dell PowerEdge™ 13th Generation Blade Servers
CONNECT - DATA SHEET
The Dell OCm14102-U4-D dual-port 10Gb Ethernet (10GbE) adapter is based on Emulex’s fourth-
generation OneConnect® Converged Network Adapter (CNA) technology, representing the
leading CNA to support Local Area Network (LAN), Storage Area Network (SAN) and Remote Direct
Memory Access (RDMA) over Converged Ethernet (RoCE) on a single 10GbE adapter.
Dell PowerEdge 13th generation servers, with Dell adapters provided by Emulex, offer multiple
benefits for the Dell enterprise customer, including:
n Accelerating workload performance through consolidation of multiple networking services on a
single high-speed Ethernet adapter platform
n Increasing data center IT agility and scalability through deployment of a secure, private or hybrid,
multi-tenant cloud infrastructure
n Maximizing server hardware utilization through CPU efficient networking
The OCm14102-U4-D dual-port 10GbE adapters offer more scalable virtualization with support for
enhanced Single-Root I/O Virtualization (SR-IOV), SMB Direct RoCE, Dell switch independent NIC
extended partitioning (NParEP) and next-generation overlay networking technologies that address
the requirements of virtual machine (VM) mobility and massive scaling of Layer 2 domains inside
private or hybrid cloud infrastructures.
Accelerated Microsoft application performance with SMB Direct RoCE support
RDMA reduces CPU utilization and data latency and improves throughput by bypassing the host
TCP/IP stack. SMB Direct RoCE leverages Converged Ethernet, also known as Data Center Bridging
(DCB), as a lossless physical layer networking medium. RoCE architecture removes the TCP/IP
stack and a data copy step. This technology works by seamlessly sensing, without user action
or intervention, the presence of an RDMA compliant adapter and switching from standard TCP/
IP networking to SMB Direct mode. Dell customers can now benefit from faster Hyper-V live
migrations and high performance Network Attached Storage (NAS) for applications such as
Microsoft SQL Server and Microsoft Unified Communications and Collaboration applications
(Exchange, Lync and SharePoint).
Emulex Virtual Network Exceleration™ (VNeX)
overlay network offloads for multi-tenant cloud networking
Dell is delivering a superior Overlay Networking solution for Dell PowerEdge 13th generation
servers, by offering the Emulex 10GbE Converged Network Daughter Card for blade servers.
Together, Dell and Emulex offer solutions that include the industry’s only hardware offload support
for Virtual Extensible Local Area Network (VXLAN) and Network Virtualization using Generic
Routing Encapsulation (NVGRE) tunnels. These solutions are designed to simplify VM mobility and
network scalability while optimizing server performance when compared to adapters that lack
offload capability.
