Adapter functionality enables reduced CPU overhead leaving more CPU resources available for
computation tasks.
Open vSwitch (OVS) offload using ASAP
• Flexible match-action flow tables
• Tunneling encapsulation/decapsulation
Support for port-based Quality of Service enabling various application requirements for latency
and SLA.
ConnectX-6 Dx provides dedicated adapter resources and guaranteed isolation and protection
for virtual machines within the server.
A consolidated compute and storage network achieves significant cost-performance advantages
over multi-fabric networks. Standard block and file access protocols can leverage
• RDMA for high-performance storage access
• NVMe over Fabric offloads for the target machine
ConnectX-6 Dx SR-IOV technology provides dedicated adapter resources and guaranteed
isolation and protection for virtual machines (VM) within the server.
• Tag Matching and Rendezvous Offloads
• Adaptive Routing on Reliable Transport
• Burst Buffer Offloads for Background Checkpointing
NVIDIA offers a full IEEE 1588v2 PTP software solution, as well as time-sensitive related features
called "5T". NVIDIA PTP and 5T software solutions are designed to meet the most demanding
PTP profiles. ConnectX-6 Dx incorporates an integrated Hardware Clock (PHC) that allows
ConnectX-6 Dx to achieve sub 20u Sec accuracy and also offers many timing-related functions
such as time-triggered scheduling or time-based SND accelerations (time-based ASAP²).
Furthermore, 5T technology enables the software application to transmit fronthaul (ORAN)
compatible in high bandwidth. The PTP part supports the subordinate clock, master clock, and
boundary clock.
ConnectX-6 Dx PTP solution allows you to run any PTP stack on your host.
NVIDIA offers ConnectX-6 Dx cards with SyncE support including an improved holdover to meet
ITU-T G.8273.2 class C.
Enabled in MCX623106TN-CDAT, MCX623106TC-CDAT,
CDAT.
NVIDIA offers ConnectX-6 Dx with an integrated GNSS receiver to allow a compact and efficient
solution for a Grand Master at every server.
Enabled in MCX623106G[N/C]-CDAT
