Mellanox Innova-2 Flex Open Benefits
Benefit | Description |
Open Platform for Custom-made Logic Accelerations | Mellanox Innova-2 Flex Open card holds a Xilinx KU15P FPGA with 520K LUTs, 70Mb of internal RAM and 1970 DSP blocks. It is a powerful tool that allows users to implement top-of-the-line acceleration engines. MNV303212A-ADLT is packed with on-board 8MB DDR4@2400MHz and connected with x8 PCIe gen4 to the host, delivering over 100Gb/s of throughput, the FPGA is primed to deliver top-notch performance and meet the most demanding offload tasks. |
Single PCIe Slot for Advanced Network Adapter and Custom Acceleration | Mellanox Innova-2 Flex Open packs Mellanox state of the art ConnectX-5 network adapter ASIC with Xilinx KU15P FPGA in one convenient HHHL adapter card, thus obviating the necessity for two separate cards for networking and offload. This frees up PCI slots for other applications, as well as saving on power. |
Ease of Deployment | Mellanox Innova-2 Flex Open is fully compatible with software running on other Mellanox ConnectX-5 adaptersa, and therefore allows a seamless transition from your current adapter to the Flex Open adapter. |
Security | Customers can integrate their proprietary security application logic and utilize both the card's FPGA offload capabilities and advanced network features to achieve highly optimized and unique solutions. Custom hardware encryption accelerators and Mellanox Innova-2 Flex Open modular board architecture can be combined to serve a variety of security use cases, including network-distributed Denial-of Service (DDoS) protection, software encryption and more. |
Storage | Mellanox Innova-2 Flex Open offers the ability to accelerate and scale different types of storage applications. For example, it can help deliver transparent data compression, decompression or de-duplication capabilities, improving overall storage utilization while not adding any additional load on the CPU. |
HPC and Machine Learning | Mellanox Innova-2 Flex Open helps to address the main challenges of HPC and Machine Learning by enabling higher speed and lower latency interconnect, and by performing customer-specific in-network compute. Mellanox Innova-2 Flex Open delivers the ability to program customer-specific in-network compute logic on top of Mellanox Innova-2 Flex Open accelerations, which include Tag Matching, RDMA and GPUDirect® with rCUDA. Communication latency can be reduced by an order of magnitude, and Machine Learning inference and training stages can be greatly accelerated by offloading specific computational elements to Mellanox Innova-2 Flex Open. |
