Five things to know about Virsto:

1. Software only
   Virsto delivers purpose-built software defined storage, integrated seamlessly into your existing VMware vCenter and Microsoft System Center VMM environment.  No new specialized hardware appliances or storage devices to take up data center space and administration resources.
2. Non-disruptive
   Virsto’s storage hypervisor delivers high performance, space efficient virtual storage at the individual VM level, serving up advanced per-VM data services from any existing block-based storage device, from JBOD to SSD.
3. More efficiency
   By delivering up to 90% more capacity from the storage you already own, Virsto lets you defer new storage purchases. Our high performance snapshots and writeable clones deliver production-speed, space-efficient thin provisioning. In doing so, Virsto makes current standard practices – over-provisioning storage capacity to ensure adequate VM performance – a thing of the past.
4. Greater agility
   To achieve the promise of the Software Defined Datacenter, storage provisioning must keep up with fluid, policy-driven enterprise computing demands. Virsto’s storage hypervisor allows you to provision storage for virtual environments in just seconds. Our solution eliminates all of the wait time associated with writing data copied over to new VMs, delivering per-VM flexibility and agility through software defined storage.
5. Better performance
   Virsto's storage hypervisor provides the best of both worlds: Up to 10x better performance than traditional thin-provisioning, while delivering up to 90% more space efficiency than thick VMDKs.
