What are the scaling downfalls of legacy NAS systems based on a 20+ year old shared-nothing storage architecture? In this episode, VAST CTO Andy Pernsteiner breaks down what a shared-nothing architecture is, it's barriers to scale and affordability, and just how to overcome them with an all-new storage architecture that enables an exabyte-scale, affordable all-flash NAS data center.
