Hyper-Converged Solutions

Organizations that are planning to upgrade or realign their datacenter solutions have to consider one important innovation: hyper-converged systems. Hyperconvergence has taken the IT storage world by storm. A hyper-converged infrastructure (HCI) enables businesses to integrate multiple IT segments into a single entity while reducing the cost and complexity involved in the process. Businesses can depend on a single vendor for support options.

What is hyperconvergence?

Hyperconvergence is a software-defined infrastructure that virtualizes all the elements of the underlying hardware. Hyperconverged platforms include a combination of the hypervisor for virtualization, a software-defined storage solution, and virtualized networking in a single system.

Hyperconverged systems allow storage systems, servers, and networking switches all to be managed as a single system, across all instances of the infrastructure. The major difference between converged and hyper-converged infrastructure is that everything ranging from storage area network as well as the storage abstractions are implemented virtually in software, in contrast, to physically in hardware as in converged infrastructure.

In simple terms, the hypervisor, storage, and server are all fused unto a single node. To scale the solution, additional nodes are deployed.

Things to know about hyper-convergence

hyper-convergedHyperconvergence has not appeared out of the blue; it is the next level of converged infrastructure. In a traditional IT environment, the storage staff handles all operations such as procurement, provisioning, deployment, and support. The same is the case with the server and networking staff. Instead of managing multiple departments, components, and training sessions, hyper-convergence enables you to combine all these components into a single entity. When computing, networking, storage, and virtualization tools are integrated as a software-defined framework, it allows organizations to scale out by leveraging innovations at the storage controller software layer.

Converged infrastructures are intended to do the same. However, hyper-converged systems focus on data control and management, so they offer software-defined storage without focusing on networking. In a converged infrastructure, separate components are engineered together for an integrated IT environment. However, a hyper-converged infrastructure is a modular system that is designed to scale out by adding extra modules. Moreover, they are built on low-cost x86 hardware. They come with a simplified architecture and a simplified management system. Hyperconverged systems are available as software, appliance, or reference architecture. You can either buy a pre-manufactured system or build your own HCI system.

Who uses hyper-converged systems?

In today’s highly competitive IT world, businesses are required to instantly provision resources. Simplicity and flexibility are the two important requirements. Organizations are looking at agile software development methodologies that provide a greater level of flexibility to get new applications up and running. Hyperconverged systems are the answer. However, the technology is still in the early stages. Most businesses are only using hyper-converged systems to deploy virtual desktop infrastructure, analytics, and general-purpose workloads. Very few companies use them for mission-critical applications and high-performance storage. However, this is expected to change quickly as organizations become more familiar with this technology.

Benefits of Hyper-converged systems

  1. Simple Deployment. Most industry-leading virtualization solutions have their own Hyperconverged Infrastructure (HCI). Hence, deploying HCI becomes simple, especially at locations where local IT staff is not available.
  2. Scalability. Since HCI has node-based architecture, it is easy to scale it up in accordance with the resource demand. It follows a building block approach, thus allowing organizations to build units as needed, thus improving scalability.
  3. Lower Costs. Models used by HCI solutions is similar to that of public cloud providers, thus reducing upfront costs and infrastructure purchases. There is less equipment that needs to be purchased, maintained, and supported in HCI. Additionally, the recurring costs of supporting the HCI data center are lower in the long term.
  4. Software-defined Storage. Software-defined storage has benefits of high reliability, redundancy, and data protection. Since HCI has software-defined storage, it reaps the benefits of software-defined storage, eventually ensuring connectivity and uptime.
  5. Simple Management. HCI solutions usually have a simple to use interface that allows workloads to run on the VM/application level. Hence, the management of the infrastructure becomes easier.
  6. Better Performance. Hyperconvergence allows organizations to deploy diverse types of applications in a shared resource pool. Since each node of the infrastructure can handle everything ranging from processing, storage, and input/output operations, organizations can focus on applications rather than individual resource needs. This in turn leads to better performance.

The future of hyper-converged systems

Hyperconverged infrastructure is not the ultimate answer to datacenter issues; there are certain limitations. For instance, you have limited options when it comes to making a granular upgrade or tweaking the system. If the storage is low and the compute is good, you still have to add extra appliances to upgrade the computing as well. Another challenge is the collaboration between different departments. For instance, storage staff may not want to expand the configuration for computing requirements or vice versa. Going forward, these issues can be addressed. As multiple vendors are collaborating on datacenter designs, hyper-converged systems are surely going to be a pivot point in shaping the changing IT technologies.
