== 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.  

'''''Value Proposition''''':  Virtualized I/O devices become much '''more configurable and scalable''' while delivering '''near-native performance''' to each VM/container/microservice, with support for confidential computing.

== SIOV R2 ==

Scalable I/O Virtualization, Revision 2 workstream 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).
