Feature Description
Storage
Acceleration
A consolidated compute and storage network achieves significant cost-performance advantages over multi-fabric networks. Standard block and file access protocols can
leverage RDMA for high-performance storage access.
• NVMe over Fabric offloads for the target machine
• T10-DIF Signature Handover
BlueField-2 SmartNIC may operate as a co-processor offloading specific storage tasks from the host, isolating part of the storage media from the host, or enabling
abstraction of software-defined storage logic
using the BlueField-2 Arm cores. On the storage initiator side, BlueField-2 SmartNIC can prove an efficient solution for hyper-converged systems to enable the host CPU to
focuson computing while all the storage interface is handled through the Arm cores.
NVMe-oF Nonvolatile Memory Express (NVMe) over Fabrics is a protocol for communicating block storage IO requests over RDMA to transfer data between a host computer and a
target solid-state storage device or system over a network. BlueField-2 DPU Controller may operate as a co-processor offloading specific storage tasks from the host using its
powerful NVMe over Fabrics Offload accelerator.
SR-IOV DPU Controller SR-IOV technology provides dedicated adapter resources and guaranteed isolation and protection for virtual machines (VM) within the server.

GPU Direct The latest advancement in GPU-GPU communications is GPUDirect RDMA. This new technology provides a direct P2P (Peer-to-Peer) data path between the GPU Memory
directly to/from the HCA devices. This provides a significant decrease in GPU-GPU communication latency and completely offloads the CPU, removing it from all GPU-GPU
communications across the network. BlueField BF2500 DPU Controller uses high-speed DMA transfers to copy data between P2P devices resulting in more efficient system
applications.
Crypto The BlueField-2 DPU Controller crypto enabled versions include a BlueField-2 IC which supports accelerated cryptographic operations. In addition to specialized instructions
for bulk cryptographic processing in the Arm cores, an offload hardware engine accelerates public-key cryptography and random number generation are enabled.
Security
Accelerators
A consolidated compute and network solution based on BlueField DPU Controller achieves significant advantages over a centralized security server solution. Standard
encryption protocols and security applications can leverage BlueField-2 compute capabilities and network offloads for security application solutions such as:
• Connection Tracking
• Statefull firewall
Out-of-Band
Management
The BlueField-2 DPU Controller incorporates a 1GbE RJ45 out-of-band port that allows the network operator to establish trust boundaries in accessing the management
function to apply it to network resources. It can also be used to ensure management connectivity (including the ability to determine the status of any network component)
independent of the status of other in-band network components.
