PeerDirect™ communication provides high-efficiency RDMA access by eliminating unnecessary internal data copies between components on
the PCIe bus (for example, from GPU to CPU), and therefore significantly reduces application run time. ConnectX-6 advanced acceleration
technology enables higher cluster efficiency and scalability to tens of thousands of nodes.
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 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 SR-IOV technology provides dedicated adapter resources and guaranteed isolation and protection for virtual machines (VM) within
the server.
The adapter supports a Network Controller Sideband Interface (NC-SI), MCTP over SMBus and MCTP over PCIe - Baseboard Management
Controller interface.
• Tag Matching and Rendezvous Offloads
• Adaptive Routing on Reliable Transport
• Burst Buffer Offloads for Background Checkpointing
The adapter supported Wake-on-LAN (WoL), a computer
network message.
In STBY mode, only port0 is available.
