What is Hyperconvergence, or HCI, or dHCI?

Posted by Roger Carson

One of the biggest concerns customers have is how far they can stretch their budget when it comes to storage. The good news is that there are many options that allow you to reduce your storage footprint without sacrificing the performance you need to run your business. One of the most popular storage solutions for small- and medium-sized businesses is called hyperconvergence.

Knowing More About Hyperconvergence

Hyperconvergence is a term that’s been around for a number of years, but it’s been on the rise recently in the market for large data centers.

The term describes a way of combining multiple servers into a single device to create a more scalable and cheaper solution. For example, a hyperconverged solution can combine multiple servers to create a single server or multiple servers to create a single data center. The technology allows organizations to deliver services more quickly, provide better services, and reduce costs.

In a nutshell, hyperconvergence is the idea of having everything in an environment that allows for the fastest possible access to your data, whether it be storage, networking, or compute. It is a growing trend in the data center to enhance your data center’s ability to store, serve and store your data at the lowest possible latency—and to do so using the lowest amount of energy possible.

HCI vs. dHCI – The Difference

Do you care which type of storage you use? If you are like most people, you probably don’t. However, because storage is a cornerstone of data center design, it’s important to understand the differences. HCI and dHCI are the two most common types of systems, and understanding how they differ is critical to understanding the potential demand for each and the current capabilities of both.

A hyperconverged infrastructure (HCI) is a new category of enterprise computing infrastructure. This means that the system spans across the data center, storage, networking, and physical server environment and capitalizes on the advantages of the converged infrastructure, such as data management and storage scalability.

This technology is the convergence of virtualized compute and storage on the same system, which simplifies the infrastructure in two ways: (1) it reduces the number of physical servers required to be deployed, and (2) it reduces the number of physical storage devices needed.

The term dHCI is the new buzzword in the distributed storage and hyperconvergence space.

The disaggregated hyper-converged infrastructure (dHCI) is a new model that combines all the benefits of the modern distributed data center (HCI) and the value of disaggregation. At its core, dHCI is a design methodology that allows a distributed storage system to scale out the centralized data storage elements and reduce cost by taking advantage of distributed processing power.

This means that it combines the benefits of modern HCI, such as easy provisioning of servers and storage, high-density deployment, and the ability to efficiently scale capacity and infrastructure, with the performance benefits of the disaggregated architecture.

HCI or dHCI – Which Is Better?

When a company builds a big data processing and analytics solution for companies, it often involves a lot of servers and a lot of infrastructures. The conventional solution is to build a HCI or HCI-like platform that includes the servers, network, storage, and software all in one place. With that, companies can easily deploy these platforms on their own and control their software stack, which helps them with flexibility and cost-efficiency. Recently, the disaggregated HCI or dHCI has emerged, which breaks the server, network, and software stack into smaller pieces that companies can easily deploy without considerable effort and investment. So, which one would you choose?

Well, HCI and dHCI are both technologies that enable data center-like performance and density in the data center. They also differ in how production-oriented they are. HCI lets you create a single blade server and scale up in size as needed, dHCI lets you create a cube (a cube by itself is called a hypercube) of servers. HCI is the option that will be more relevant for the enterprise because it can be used to replace multiple servers, while dHCI is useful only for the data center.

Conclusion

Hyperconverged infrastructure (HCI) and disaggregated hyper-converged infrastructure (dHCI) are two of the most common terms you’ll hear about for data center infrastructure and software these days. In a nutshell, HCI and dHCI are the most common options for modern data center environments that use the software defined data center (SDDC) platform and software defined storage (SDS) capabilities. HCI and dHCI are keys to the modern data center, which is why they are often lumped together.
