Hyper-converged infrastructure
A hyper-converged infrastructure (aka hyperconvergence) is an IT infrastructure framework for integrating storage, networking and virtualization computing in a data center.[1] In a hyperconvergence environment all elements of the storage, compute and network components are optimized to work together on a single commodity appliance from a single vendor.[2][3][4] The term is a neologism of Converged infrastructure.[5][6]
Features
At a high level, hyperconvergence can support data center availability and reliability requirements, infrastructure is managed and workloads are deployed through a single interface to the underlying operating hardware.[7] The difference between converged and hyper-converged infrastructures is that the building blocks of each of the subsystems in converged infrastructures are used for their originally intended purposes the server is separate and used as a server, just as the storage subsystem is separate and used as functional storage.[8][9][10]
An important aspect of hyperconvergence is to move away from monolithic, hardware-defined infrastructures and evolve into software-defined intelligent environments.[11][12][13] Its infrastructures are made up of commodity x86-based servers equipped with direct-attached storage.[14][15] It includes the ability to plug and play into the data center pool.[16][17] All physical data center resources reside on a single administrative platform for both hardware and software layers.[18] Optimally utilizing commodity servers for infrastructure needs, together with single vendor management, eliminates traditional data center inefficiencies and reduces the total cost of ownership (TCO) for data centers.[19][20][21][22]
Potential impact
The potential of the hyper-converged infrastructure defined data center is that companies will no longer need to rely [23] on different hardware and software, rather it will define applications and all of the resources they require including compute, storage, networking, security, and availability. It is likely to further drive down prices for data center hardware and simplifies management and increase resource-utilization rates.[24][25][26] A Converged infrastructure fosters IT objectives by implementing pools of computers, storage and networking resources that can be shared by multiple applications and managed collectively.[27][28]
