Scalable I/O Virtualization (SIOV)
SIOV is hardware-assisted I/O virtualization designed for the hyperscale era, with the potential to support thousands of virtualized workloads per server.
- SIOV moves the non-performance-critical virtualization and management logic off the device and into the virtualization stack. It uses a scalable identifier on the device to address the workloads’ memory.
SIOV delivers key benefits vs. prior art:
- Reduces the per-VM virtualization cost on the devices
- More efficiently supports large numbers of VMs and containers
- Provides more flexibility to the virtualization stack for provisioning & composability.
Benefit: Virtualized I/O devices become much more configurable and scalable while delivering near-native performance to each VM/container/microservice.
SIOV R1
Scalable I/O Virtualization, Revision 1 was contributed to OCP by Intel and Microsoft:
SIOV R2
Scalable I/O Virtualization, Revision 2 working group scope:
- Ensure specification is compatible across multiple host and device architectures to provide a consistent usability experience.
- Ensure specification meets new, emerging, and complementary usages (confidential computing, etc.).
- Ensure a viable ecosystem transition path to SIOV Revision 2.0 from existing ecosystem (SR-IOV, SIOV R1).
