Larger, expandable HCI nodes bring big infrastructure benefits

A majority of hyper-converged infrastructure deployments start with three to four HCI nodes that support relatively basic workloads. However, when an organization decides to add more workloads, especially storage-intensive ones, problems can arise. At the heart of the problem is how HCI typically scales three resources -- compute, storage and networking -- in lock-step even though those resources rarely need to scale at the same pace. Eventually, one or two of them become significantly underutilized. More efficient use of HCI resources is critical to engender widespread enterprise adoption. Using HCI for only a few workloads and having other more storage-intensive workloads running on isolated hypervisor clusters or bare-metal systems essentially eliminates the value proposition of HCI. Organizations adopting the technology should aim for the opposite outcome, centralizing all -- or all but a few -- workloads in the HCI environment. HCI environments consist of a cluster of physical servers, called nodes. HCI nodes run on the ...
