Is HCI a True VMware Alternative?
Storage Switzerland, Tuesday, January 28th, 2025
As IT organizations evaluate their options for exiting VMware, many available options are hyperconverged infrastructure (HCI) as a potential replacement. It makes sense. HCI proposes simplifying IT administrators' lives by converging all of the various components of their infrastructure.
The problem is that HCI just packages virtualization, storage, and networking; it does not integrate them into a single code base. Instead, it recreates the legacy three-tier design, except in software. It ignores the fourth infrastructure tier, data resiliency and protection. As a result, the HCI approach introduces performance, scalability, compatibility, and data vulnerability challenges that must be considered before making the transition.
The Performance and Scalability Limitations of HCI
A key architectural challenge with HCI is that storage and networking are implemented as virtual machines (VMs) rather than core components of the infrastructure software.
