Where virtual computing is headed

Virsto already delivering on these value propositions

CLOUD SCALE

Beyond thestorage array

VASTLY HIGHER UTILIZATION

Always thinly provisioned,no VM duplication

VIRTUAL STORAGE ARCHITECTURE

Abstract VM storagefrom hardware

RADICALLY NEW ECONOMICS

Distributed, commodity,hardware independent

VDI complicates the storage problem

VDI workloads even more random,

write intensive

Much wider variability between peak

and average IOPS

Scale: provisioning/managing

thousands of VM images

VDI storage costs even higherAugust 2011 © Virsto, confidential
