As you can see, hyperconvergence is a drastically different approach to a data center. It removes the SAN completely. The hypervisor, server, and storage are now all fused into a single appliance called a node. To scale the solution, you just need to deploy additional nodes.
In the design, you’ll notice that the hyperconvergence solution includes both a solid state drive (SSD) and a hard disk drive (HDD), but this may vary by developer. There are all flash hyperconvergence solutions on the market today.
Finally, hyperconvergence is sometimes described as the software defined data center (SDDC), because a hyperconverged infrastructure is managed centrally by a single piece of software. Storage, compute, and the virtual machines are all managed by that same application.
Besides consisting of less physical equipment, hyperconvergence provides a number of important benefits to the IT environment and the business as a whole.
1) Software-defined storage in a hyperconverged infrastructure is software-defined. The storage nodes act as one highly-reliable and redundant pool of storage. Should one node go down, the rest will remain unaffected.
2) Agility: In a hyperconverged infrastructure, your workloads all fall under the same administrative umbrella. This makes it easier to migrate workloads from one location to another.
3) Scalability: Because of the node-based architecture, it is very easy to scale up your hyperconverged data center. Simply add or subtract nodes to match your resource demand.
4) Data protection: Hyperconvergence gives an organization the ability to easily restore data.
5) Cost efficiency: Hyperconvergence brings an affordable economic model to any IT department. Because there is less equipment to purchase, maintain, and support, the recurring costs of supporting a hyperconverged data center are lower.
By delivering virtualization, storage, compute, network, management and data protection in an easy to manage but scalable application, an organization has the ability to seamlessly manage their complex infrastructure. Hyperconvergence is definitely emerging as a pivotal architecture for organizations of all sizes. Not only is it cost effective, but it plays a very important role in managing a company’s infrastructure.
