Introducing Hyper-Converged Infrastructure


Introducing Hyper-Converged Infrastructure



LIMA has considerable experience in designing, delivering and supporting converged infrastructure platforms.  Recently, we have seen an interest in the relatively new kid on the block – the hyper-converged infrastructure  The two platforms have fundamental distinctions, so this blog takes a first look at the key differences to help our customers identify where HCI fits in the IT infrastructure landscape.

Converged Infrastructure

Converged Infrastructure (CI) is a proven datacentre technology stack consisting of compute, storage, networking and hypervisor that is provisioned as a single platform with known capabilities and compatibilities across the physical stack ensuring the platform is quick to deploy, easy to maintain and has pre-validated builds. 

CI allows higher flexibility within the stack of physical options, allowing for a very granular design of the platform elements. This ensures that the platform receives the correct sizing for the type of storage, compute and networking.  Typically, a CI platform is sized up front and includes additional growth. It is normally purchased as a single platform in a capex model.

Hyper-Converged Infrastructure

Hyper-Converged Infrastructure (HCI) takes the separate commodity hardware elements - compute, storage, networking and hypervisor - and condenses them into dedicated nodes/appliances that easily scale as the resourcing needs increase and most importantly adds a software defined layer to all elements creating automation and orchestration across the entire platform.

Typically, HCI takes a module-based approach where the platform is first sized based on the immediate requirements and additional nodes procured as required.  Additional nodes provide an increase to the specific resources that need expanding.  Typically, HCI is deployed as a hybrid solution alongside the existing legacy platform and expands as the company transitions into cloud/hybrid cloud platforms.

In the right environment, HCI can reduce CAPEX and OPEX costs by up to 50%.

When is a good time to investigate HCI further?

  • If you’re running out of primary storage for VMs

  • If you’re experiencing VM performance degradation

  • If your storage or server hardware is coming to end of life/lease
