Item Description
“SMBus Interface” Allows BMC connectivity using MCTP over SMBus or MCTP over PCIe protocols.
“Voltage
Regulators”
Voltage supply pins that feed onboard regulators.
“CPLD Interface” Controls the networking port LEDs.
ConnectX-6 Dx IC
The ConnectX®-6 Dx EN family of adapter IC devices delivers two ports of 10/25/40/50/100Gb/s or a
single-port of 200Gb/s Ethernet connectivity paired with best-in-class hardware capabilities that
accelerate and secure cloud and data-center workloads.
Encryption
ConnectX-6 Dx brings security to every end-point, including:
Purpose-built inline acceleration engines that offload IPsec and TLS data-in-motion and XTS-
AES data-at-rest cryptographic operations.
Stateful firewall solution acceleration, powered by Open vSwitch connection tracking and
Mellanox’s ASAP2 technology.
Embedded hardware root-of-trust and support for RSA-based secure firmware update and
secure boot, providing guaranteed integrity of the network adapter.
Ethernet SFP28/SFP56/QSFP56 Interfaces
The network ports of the ConnectX®-6 Dx adapter card are compliant with the IEEE 802.3 Ethernet
standards listed inFeatures and Benefits. Ethernet traffic is transmitted through the QSFP56
connectors on the adaptercard.
