IOV hardware and software plumbing for VMware ESX - journey to uncompromised I/O Virtualization and Convergence

*

One Line Summary

Integration of VMware ESX para-virtual and passthru I/O "plumbing", 10GbE IOV, and protocol acceleration.

Abstract

The dominant trends for I/O “plumbing” in datacenter and cloud are I/O virtualization, I/O fabric convergence, and network/storage/security protocol acceleration.
These trends are not always complimentary. As applications migrate from dedicated servers to virtual machines, they often lose many customary features and performance guarantees. Improving hardware and software I/O support in hypervisors started to bridge this gap, with much still to be done.
The talk will cover the following:
- use of hardware IOV and drivers to provide guaranteed SLA and isolation to multiple “tenants” sharing VMware ESX I/O.
- use of ESX 4.x VMDirectPath (passthru) to recover the cost of I/O para-virtualization.
- mechanisms for delivering network/storage/security hardware acceleration to guest OSes running in ESX and other hypervisors.
