Feature
Description
Storage
Acceleratio
n
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 target machine
• Erasure Coding
• T10-DIF Signature Handover
SR-IOV
Mellanox ConnectX-6 Dx SR-IOV technology provides dedicated adapter resources and guaranteed
isolation and protection for virtual machines (VM) within the server.
High-
Performan
ce Accelera
tions
• Tag Matching and Rendezvous Offloads
• Adaptive Routing on Reliable Transport
• Burst Buffer Offloads for Background Checkpointing
PPS In/Out
SMAs
Mellanox offers a full IEEE 1588v2 PTP software solution, as well as time-sensitive related
features called “5T”. Mellanox PTP and 5T software solution 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, the 5T technology enables the software application to transmit fronthaul
(ORAN) compatible in high bandwidth. The PTP part supports slave clock, master clock, and
boundary clock.
ConnectX-6 Dx PTP solution allows you to run any PTP stack on your host.
With respect to testing and measurements, selected Mellanox adapters allow you to use the PPS-
out signal from onboard SMA connecter, ConnectX-6 Dx also allows to measure PTP in scale, with
PPS-In signal. The PTP HW clock on the Network adapter will be sampled on each PPS-In signal,
and the timestamp will be sent to the SW.
Enabled in MCX623106PN-CDAT, MCX623106PE-CDAT and MCX623106PC-CDAT.
