Abstract
A modern data center typically contains a number of specialized storage systems which provide centralized storage for a large collection of data center applications. These specialized systems were designed and implemented as a solution to the problems of scalable storage, 24x7 data access, centralized data protection, centralized disaster protection strategies, and more. While these issues remain in the data center environment, new applications, new workload profiles, and the changing economics of computing have introduced new demands on the storage system which drive towards new architectures, and ultimately towards a hyperconverged architecture. After reviewing what a hyperconverged architecture is and the building blocks in use in such architectures, there will be some predictions for the future of such architectures.

Definition
Hyper-convergence (hyperconvergence) is a type of infrastructure system with a software-centric architecture that tightly integrates compute, storage, networking and virtualization resources and other technologies from scratch in a commodity hardware box supported by a single vendor

Why Hyperconverged
If it’s so good, why haven’t we been
using it all along?
