• SPI - includes 256Mbit SPI Quad Flash device.
• FRU EEPROM - Stores the parameters and personality of the card. The EEPROM
capacity is 128Kbit (or 16KB). FRU I2C address is (0x50) and is accessible
through the PCIe
In order to better scale their networks, datacenter operators often create overlay
networks that carry traffic from individual virtual machines over logical tunnels in
encapsulated formats such as NVGRE and VXLAN. While this solves network scalability
issues, it hides the TCP packet from the hardware offloading engines, placing higher
loads on the host CPU. ConnectX-7 effectively addresses this by providing advanced
NVGRE and VXLAN hardware offloading engines that encapsulate and de-capsulate the
overlay protocol.
Support for port-based Quality of Service enabling various application requirements
for latency and SLA.
