On April 24 VMware published a technical paper titled: The VMware Reference Architecture for Stateless Virtual Desktops on Local Solid-State Storage with VMware View 5 which introduce the use of local solid-state drives (SSDs) within a physical host to offload the majority of desktop virtualization IOPS needed.
The objective of this model is to significantly reduce the hardware infrastructure costs of desktop virtualization environments while providing an highly scalable architecture.
