What Is RoCEv2?

RoCEv2 (RDMA over Converged Ethernet v2) is a protocol that implements RDMA on Ethernet. Its packets are encapsulated in UDP/IP, so they can be routed across layer-3 networks. RDMA moves data directly between the memory of two machines, bypassing the operating-system kernel, which keeps latency and CPU usage low.

Nearby terms

NVMe-oF
NVMe-oF (NVMe over Fabrics) extends the NVMe protocol from the PCIe bus inside a server onto the network, so that many servers can share remote NVMe storage over Ethernet, InfiniBand and other fabrics while keeping performance close to a local drive.
HBM (high-bandwidth memory)
HBM (high-bandwidth memory) is the stacked, high-bandwidth memory used on AI accelerators, in other words GPU memory. It is extremely fast but limited in capacity and expensive, and model weights and KV cache compete for it.

Test jointly first, decide afterwards

Every engagement starts with a gated joint test of about 10 weeks. Four gates are passed in sequence; if one is missed, the project stops there, so you never pay for a benefit that was not demonstrated.
