Learn how GPUs, NVMe drives and other IO devices can be efficiently shared in a PCI Express network using SmartIO from Dolphin Interconnect Solutions.
Traditionally, IO devices are statically assigned to a single root complex (host machine), and features such as hot-add, device migration and remote access are not supported flexibly without complex software frameworks. SmartIO eliminates these restrictions and provides a flexible framework for handling PCIe devices and systems. Devices such as GPUs, NVMe drives and other IO devices can be flexibly accessed from remote systems.
We demonstrate how SmartIO is implemented using standard PCIe and Non-Transparent Bridging, show that our system got near-native performance when moving data borrowed GPUs and NVMe drives. We also show how we can dynamically add more GPUs to scale performance.
