BenefitsNVIDIA LinkX Ethernet cables and transceivers are designed to maximize the performance of High-Performance Computing networks, requiring high-bandwidth, low-latency connections between compute nodes and switch nodes. NVIDIA offers one of the industry’s broadest portfolios of 40Gb/s, 56Gb/s and 100Gb/s cables, including Direct Attach Copper cables (DACs), copper splitter cables, Active Optical Cables (AOCs) and transceivers in a wide range of lengths from 0.5m to 10km. In addition to meeting Ethernet standards, NVIDIA tests every product in an end-to-end environment ensuring a Bit Error Rate of less than 1E-15.
 

Telecommunications service providers are moving towards

disaggregation, server virtualization, and orchestration as key tenets to

modernize their networks. Likewise, they’re also moving towards Network

Function Virtualization (NFV), which enables the rapid deployment of new

network services. With this move, proprietary dedicated hardware and

software, which tend to be static and difficult to scale, are being replaced

with virtual machines running on commercial off-the-shelf (COTS) servers.

For telecom service providers, choosing the right networking hardware is

critical to achieving a cloud-native NFV solution that is agile, reliable, fast

and efficient.

Telco service providers typically leverage virtualization and

cloud technologies to better achieve agile service delivery and efficient

scalability; these technologies require an advanced network infrastructure

to support higher rates of packet processing. However, the resultant

east-west traffic causes numerous interrupts as I/O traverses from kernel

to user space, eats up CPU cycles and decreases packet performance.

Particularly sensitive to delays are voice and video applications which

often require less than 100ms of latency.

ConnectX-5 adapter cards drive extremely high packet rates, increased

throughput and drive higher network efficiency through the following

technologies; Open vSwitch Offloads (OvS), OvS over DPDK or ASAP²,

Network Overlay Virtualization, SR-IOV, and RDMA. This allows for secure

data delivery through higher-performance offloads, reducing CPU resource

utlization, and boosting data center infrastructure efficiency. The result is

a much more responsive and agile network capable of rapidly deploying

network services.
