Borrowing Pooled Devices

SmartIO supports multiple ways to use devices added to the SmartIO pool, including borrowing with device lending, both bare-metal and with guests, and using the SISCI API for low level access. See the sub-pages for more details.

Borrowing Device	Driver Software	Concurrent Use
Using Native Device Drivers	Native driver	Only with SR-IOV devices
Passthrough of non-SR-IOV pooled devices to unmodified guests	Native guest driver	None
Using Dolpin dis_nvme driver	Dolphin’s dis_nvme driver	Yes, non-SR-IOV NVMe drives can be shared in a cluster
SmartIO with SISCI	Driver must be ported or developed for SISCI API	Yes, but must be coordinated by driver software
