Top 10 Hyperconverged Infrastructure (HCI) Solutions

hyperconverged infrastructure (HCI) solution is a primary tool for connecting, managing and operating interconnected enterprise systems in a hyperconverged infrastructure (HCI). The technology helps organizations virtualize storage, servers, and networks. While converged infrastructure uses hardware to achieve this objective, HCI takes a software-centric approach.

To be sure, hyperconvergence has its pros and cons. Yet the advantages are clear: HCI boosts flexibility by making it easier to scale according to usage demands and adjust resources faster and more dynamically. By virtualizing components it’s possible to build more efficient databases, storage systems, server frameworks and more. HCI solutions increasingly extend from the data center to the edge. Many also incorporate artificial intelligence and machine learning to continually improve, adapt and adjust to fast-changing business conditions. Some also contain self-healing functions.

By virtualizing an IT environment an enterprise can also simplify systems management and trim costs. This can lead to a lower total cost of ownership (TCO).  Typically, HCI environments use a hypervisor, usually running on a server that uses direct-attached storage (DAS), to create a data center pool of systems and resources. Most support heterogenous hardware and software systems. The end result is a more flexible, agile and scalable computing framework that makes it simpler to build and manage private cloudpublic clouds and hybrid clouds.

How to Select the Right HCI Solution

A number of factors are important when evaluating HCI solutions. These include:

Edge-core cloud integration. Organizations have vastly different needs when it comes to connecting existing infrastructure, clouds and edge services. For instance, an organization may require only the storage layer in the cloud. Or it may want to duplicate or convert configurations when changing cloud providers. Ideally, an HCI solution allows an enterprise to change, upgrade and adjust as infrastructure needs change.

Analytics. It’s crucial to understand operations within an HCI environment. A solution should provide visibility through a centralized dashboard but also offer ways to drill down into data, and obtain reports on what is taking place. This also helps with understanding trends and doing capacity planning.

Storage management. An HCI solution should provide support for setting up and configuring a diverse array of storage frameworks, managing them and adapting them as circumstances and conditions change. It should make it simple to add nodes to a cluster and support things like block file and object-oriented storage. Some systems also offer NVMeOF (non-volatile memory express over fabrics) support, which allows an enterprise to rearchitect storage layers using flash memory.

Hypervisor ease of use. Most solutions support multiple hypervisors. This increases flexibility and configuration options—and it’s often essential in large organizations that rely on multiple cloud providers. But it’s important to understand whether you’re actually going to use this feature and what you plan to do with it. In many cases, ease of use and manageability are more important than the ability to use multiple hypervisors.

Data protection integration. It’s important to plug in systems and services to protect data—and apply policy changes across the organization. It’s necessary to understand whether this protection is scalable and adaptable, as conditions change. Ideally, the HCI environment can replace disparate backup and data recovery systems. This greatly improves manageability and reduces costs.

Container support. A growing number of vendors support containers, or plan to do so soon. Not every organization requires this feature, but it’s important to consider whether your organization may move in this direction.

Serverless support. Vendors are introducing serverless solutions that support code-triggered events. This has traditionally occurred in the cloud but it’s increasingly an on-premises function that can operate within an HCI framework.

Here are ten leading HCI solutions:
