The concept of the software-defined datacenter (SDD) is gaining recognition, as IT moves away from infrastructure traditionally defined by hardware toward a more flexible infrastructure built around software and dynamic allocation of resources. In the SDD, all virtualized storage, server, networking and security resources required by an application can be defined by software and provisioned automatically. Virsto’s VM-centric storage hypervisor is purpose built to deliver software-defined storage: the missing link for storage agility, performance and efficiency to realize more agile IT.

1. The Storage Hypervisor:
The missing link for the Software Defined Datacenter
Gregg Holzrichter,
Aug 2012 VP Marketing

2. VMware’s Software Defined Datacenter Vision
The foundation for cloud computing.
Intelligent software that abstracts out hardware resources,
pools it into aggregate capacity, enabling automation to efficiently dole it out
as needed by applications.

3. Storage is the remaining impediment to the
Software Defined Datacenter
Compute & Network Current Storage Architecture:
now Pooled, Agile not virtualization ready
Native Hypervisor Storage Options:
