PowerScale was among the first storage platforms to support NFSoRDMA and NVIDIA’s GPUDirect Storage, GDS. The low latency direct transfer of data between storage and GPU memory that GDS enables ensures that PowerScale can keep GPUs utilized while running large, demanding AI models.
PowerScale OneFS supports Remote Direct Memory Access (RDMA) over converged Ethernet (RoCEv2). When paired with NFS to enable NFSoRDMA, data is sent directly from the PowerScale network adapter to the compute or application memory, bypassing CPU and operating systems. Combining NFSoRDMA with NVIDIA’s GPUDirect Storage and MagnumIO software modules, data can be transferred directly between NVIDIA GPU memory and PowerScale storage over a low latency, highly efficient network.
