TCP/IP, UDP checksum offload (TCO) moves the TCP and IP checksum offloading from the CPU to the network adapter. Large send offload (LSO) or TCP segmentation offload (TSO) allows the TCP segmentation to be handled by the adapter rather than the CPU.

When connected to Hewlett Packard Enterprise Virtual Connect FlexFabric 20/40 F8 Modules, the HPE FlexFabric 650M adapter provides 20GbE performance. It offers a rich set of offload technologies including overlay network tunneling and storage, increasing virtualization performance and host efficiency. The HPE 650M is a dual-speed adapter that can also operate at 10GbE when connected to Hewlett Packard Enterprise Virtual Connect Flex-10/10D Module or HPE 6125XLG Ethernet Switch. Combining both the FlexibleLOM and Mezzanine adapters in a single BladeSystem ProLiant server can provide up to 80Gb/s of converged bi-directional Ethernet bandwidth, helping to alleviate network bottlenecks.

Notes:
This adapter requires a minimum of 2GB of server memory.
This adapter supports linking at 10Gb/s when not connected to a Flex-20 device.
