nts
SPI - includes 256Mbit SPI Quad Flash device.
FRU EEPROM - Stores the parameters and personality of the card. The EEPROM capacity is
128Kbit. FRU I2C address is (0x50) and is accessible through the PCIe SMBus. (Note:
Address 0x58 is reserved.)
Overlay
Networks
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.
Quality of
Service
(QoS)
Support for port-based Quality of Service enabling various application requirements for latency
and SLA.
