What is hyperconverged infrastructure?

Hyperconverged infrastructure (HCI) is a combination of servers and storage into a distributed infrastructure platform with intelligent software to create flexible building blocks that replace legacy infrastructure consisting of separate servers, storage networks, and storage arrays. More specifically, it combines commodity datacenter server hardware with locally attached storage devices (spinning disk or flash) and is powered by a distributed software layer to eliminate common pain points associated with legacy infrastructure.

How does hyperconverged infrastructure help with IT efficiency?

HCI reduces your datacenter footprint by reducing typical infrastructure stacks down to scalable building blocks with compute, storage, and networking built in. And this drastically reduced footprint enables you to run the same infrastructure at the edge as in your core datacenters, resulting in additional efficiency while improving resiliency and performance.

What is the difference between converged and hyper converged?

Converged infrastructure (CI) is a different way of purchasing traditional infrastructure and is typically pre-integrated by a vendor or Systems Integrator. Despite pre-integration, CI is built on the same hardware-centric components, and it doesn’t remove organizational silos or solve the problems related to traditional infrastructure. In contrast, Hyperconverged Infrastructure (HCI) completely re-thinks the way infrastructure can be designed, purchased, deployed, managed, and expanded.

Is hyperconvered infrastructure technology scalable?

Similar to public cloud services, hyperconverged infrastructure solutions enable IT teams to start with what they need today and scale incrementally to precisely meet application demands. With HCI, you can non-disruptively scale out your environment with modular building blocks as your business needs grow. In contrast, with traditional infrastructure, each tier is sized based on specific needs.

Can hyperconvergence simplify storage?

Data is growing at 50% or more per year, and that data is stored on block, file, and object storage. New requirements for visibility and control are increasing demands on storage administrators. And cloud storage has become an important tier that must be considered in any storage architecture. But traditional storage infrastructure can’t keep up with the demands caused by these new realities. It’s siloed, which creates complexity, limits flexibility, and reduces utilization.

What applications can be run on hyperconverged infrastructure?

Some prime examples of what apps run on HCI: Databases: Oracle, SAP HANA, Microsoft SQL Server, MySQL, PostgreSQL, IBM DB2, and many others Business Critical Applications: Virtualized server applications like Oracle E-Business Suite, SAP Business Suite, Microsoft Dynamics, Epic, Meditech and more, supported on all major hypervisors Big data: Splunk, MongoDB, Elastic, Hadoop and more Cloud-native: Build and deploy cloud native applications with Kubernetes, Docker, Puppet, ChefVirtual desktop infrastructure (VDI): Citrix, VMware Horizon Remote Office and Branch Office (ROBO): Print and file servers, office services, custom applications

What kind of hardware is used with hyperconverged infrastructure environments?

The components of HCI include a distributed infrastructure plane and a distributed management plane.The distributed infrastructure plane runs across a cluster of nodes delivering storage, virtualization, and networking services for guest applications—whether they’re VMs or container-based apps. The management plane lets you easily administer your global HCI resources from one place and one view. It eliminates the need for separate management solutions for servers, storage networks, storage, and virtualization.
