According to Mellanox, the two new BlueField storage controllers can hit over 4 million IOPS with NVMe-oF. If the network is configured as either Ethernet or InfiniBand, the controllers are able to hit up to 200Gb/s of network and PCIe bandwidth. This level of performance gives the new controllers an edge over NVMe over RoCE (RDMA over Converged Ethernet), InfiniBand, and TCP/IP. The BlueField SoC integrates the ConnectX-5 network adapter, which allows for a a fully-programmable environment for storage software such as compression, encryption, RAID, and virtualization. The BlueField BF1600 and BF1700 also include smart offloads for storage including NVMe-oF, erasure coding, and T10-DIF data integrity signatures.
