The format and definition of the MAC header is outside the scope of this annex.Description. The eBook, "NVMe over RoCE Storage Fabrics for Noobs!", is now available!

Software support for RoCE v2 is still emerging. Mellanox OFED 2.3 or later has RoCE v2 support and also Linux Kernel v4.5. NVMe over RoCE is a new type of SAN. This protocol provides the same enterprise data services performance and flexibility of ...RoCE v2: The RoCE v2 protocol overcomes the limitation of version 1 being bounded to a single broadcast domain (VLAN). By changing the packet encapsulation to include IP and UDP headers, RoCE v2 can now be used across both L2 and L3 networks. This enables Layer 3 routing, which brings RDMA to network with multiple subnets for great scalability.How Instance Metadata Service Version 2 works. IMDSv2 uses session-oriented requests. With session-oriented requests, you create a session token that defines the session duration, which can be a minimum of one second and a maximum of six hours. During the specified duration, you can use the same session token for subsequent requests.Latest Infrastructure & Networking topics - NVIDIA Developer Forums.
