ConnectX-7 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
•
NVMe over TCP acceleration
ConnectX-7 SR-IOV technology provides dedicated adapter resources and guaranteed
isolation and protection for virtual machines (VM) within the server.
•
Collective operations offloads
•
Vector collective operations offloads
•
MPI tag matching
•
MPI_Alltoall offloads
•
Rendezvous protocol offload
330-370 million messages per second.
The secure boot process assures booting of authentic firmware/software that is
intended to run on ConnectX-7. This is achieved using cryptographic primitives using
asymmetric cryptography. ConnectX-7 supports several cryptographic functions in its
HW Root-of-Trust (RoT) that has its key stored in on-chip FUSES.
The Secure firmware update feature enables a device to verify digital signatures of
new firmware binaries to ensure that only officially approved versions can be installed
from the host, the network, or a Board Management Controller (BMC). The firmware
of devices with "secure firmware update" functionality (secure FW), restricts access
to specific commands and registers that can be used to modify the firmware binary
image on the flash, as well as commands that can jeopardize security in general.
For further information, refer to
Block-level encryption and checksum offloads.
ConnectX-7 technology maintains support for host manageability through a BMC.
ConnectX-7 PCIe stand-up adapter can be connected to a BMC using MCTP over SMBus
or MCTP over PCIe protocols as if it is a standard NVIDIA PCIe stand-up adapter card.
For configuring the adapter for the specific manageability solution in use by the
server, please contact NVIDIA Support.
