NVMe-oF Targets

NVMe-oF targets provide block access using the NVMe protocol over a network. eEKAS exposes NVMe-oF over TCP and can also use RDMA/RoCE when suitable hardware or a software RoCE configuration is available.

Target types

  • NVMe-oF over TCP works over Ethernet and is the general-purpose option for NVMe network access.
  • NVMe-oF over RDMA uses RDMA-capable Ethernet or InfiniBand. If no RDMA-capable device is present, eEKAS shows a note that software RoCE can be created in Network Management.

When to choose NVMe-oF

  • Use NVMe-oF for latency-sensitive block workloads where client operating systems support it.
  • Use NVMe/TCP when you want broad compatibility over standard Ethernet.
  • Use RDMA/RoCE only when the network has been designed and tested for it.

Before going live

  • Confirm IP Group placement and failover behavior.
  • Verify MTU and network configuration on every participating node.
  • Test reconnect behavior from the client before placing production workloads on the target.
