Feature
Description
Mellanox PeerDirect™
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-5
advanced acceleration technology enables higher cluster efficiency
and scalability to tens of thousands of nodes.
CPU Offload
Adapter functionality enabling reduced CPU overhead allowing more
available CPU for computation tasks.
Open vSwitch (OVS) offload using ASAP
2(TM)
•
Flexible match-action flow tables
•
Tunneling encapsulation/decapsulation
Quality of Service (QoS)
Support for port-based Quality of Service enabling various
application requirements for latency and SLA.
Hardware-based I/O Virtualization
ConnectX-5 provides dedicated adapter resources and guaranteed
isolation and protection for virtual machines within the server.
Storage Acceleration
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
•
Erasure Coding
•
T10-DIF Signature Handover
SR-IOV
ConnectX-5 SR-IOV technology provides dedicated adapter
resources and guaranteed isolation and protection for virtual
machines (VM) within the server.
NC-SI
The adapter supports a Network Controller Sideband Interface (NC-
SI), MCTP over SMBus and MCTP over PCIe - Baseboard
Management Controller interface.
