Enable NVMe Storage over Ethernet on your FPGA — Low-Cost, Reliable, Scalable
Keep your NVMe SSDs in the rack or in the network, yet access them like local drives over the Ethernet you already own. Design Gateway's NVMeTCP-IP core offloads the full NVMe/TCP stack into FPGA logic — delivering remote storage with zero host-CPU protocol load.
|
Keep Compute Where It Is. Move the Media to the Network.
NVMe/TCP is the most affordable network storage protocol — running over standard Ethernet with no dedicated switches or HBAs. When the full stack runs in FPGA hardware, it wins over RDMA (RoCE) and Fibre Channel on three key fronts:
|
Why NVMe/TCP Wins
| 💰Low-Cost — commodity Ethernet switches and cabling; no expensive FC fabric or lossless RDMA switches required |
| 🛡️Reliable — TCP's acknowledgment mechanism retransmits lost data automatically, even on standard lossy networks |
| 📈Scalable — add hosts and SSDs through general Ethernet switches; no special fabric or topology rules |

Story 1 — Scalable NVMe over TCP Initiator on Alveo U50
|
|
Four Remote SSDs, Four Independent 25G Links, Zero CPU Load
DG's Alveo U50 reference design gives a host parallel access to four NVMe SSDs over four independent 25G NVMeTCP links. Each NVMeTCP25G-IP core runs one NVMe/TCP session in hardware, with PCIe/XRT DMA moving data straight to host memory — ideal for AI/HPC, video processing, and high-speed data acquisition.

Story 2 — Cloud Storage Accelerator
|
|
Remote NVMe for VMs — with the Host CPU Set Free
DG's Cloud Storage Accelerator (with DYNANIC) offloads NVMe/TCP into FPGA hardware so VMs reach remote NVMe SSDs over standard Ethernet while the CPU stays on VM workloads. Compared to Fibre Channel, NVMe/TCP over Ethernet is the lower-cost, more scalable path — without dedicated FC switches or HBAs.

|
NVMe/TCP vs Fibre Channel
For cloud storage gateways, NVMe/TCP over standard Ethernet consistently beats Fibre Channel on cost, scalability, and manageability.
