Converged and Hyperconverged Infrastructure: One System Instead of Three Silos
Converged infrastructure (CI) and hyperconverged infrastructure (HCI) are two ways to simplify the data center by integrating compute, storage and networking. Converged infrastructure pre-validates discrete components into one supported stack; hyperconverged infrastructure goes further, running compute and software-defined storage together on clustered industry-standard nodes, with no separate SAN, scaled by adding nodes and managed from one console.
The appeal is operational. Three-tier infrastructure, separate servers, SAN and switches, is flexible but complex, with separate teams, tools and refresh cycles. CI and HCI reduce that to a single system, which is why they dominate virtualisation, VDI and edge. And with VMware licensing costs rising after the Broadcom acquisition, the choice of HCI platform and hypervisor has become one of the most consequential infrastructure decisions enterprises face.
Three-Tier, Converged or Hyperconverged?
The three architectures suit different workloads and operating models. The table below sets out where each fits.
| Architecture | What it is | Best for | Examples |
|---|---|---|---|
| Three-tier | Separate compute, storage and network, managed independently | Large, specialised or high-performance workloads | Servers plus SAN plus switches |
| Converged (CI) | Pre-validated stack of discrete compute, storage and network | Standardised deployments, predictable scaling | Reference architectures on Dell, HPE |
| Hyperconverged (HCI) | Software-defined compute and storage on clustered nodes | Virtualisation, VDI, edge, simpler operations | Nutanix, Dell VxRail, HPE SimpliVity |
HCI is the fastest-growing of the three because it removes the separate SAN and the specialism it demands. An HCI cluster typically starts at three nodes and grows in single-node increments, so capacity is added in small, predictable steps. Platforms such as Nutanix, Dell VxRail and HPE SimpliVity, along with disaggregated options like HPE Alletra dHCI where compute and storage still scale separately, cover most enterprise cases.
VMware Alternatives: Choosing a Hypervisor After the Broadcom Change
The Broadcom acquisition of VMware moved licensing to subscription bundles and raised costs for many customers, which has put the hypervisor choice back on the table for the first time in years. The main options are below.
| Hypervisor | Strengths | Best for |
|---|---|---|
| VMware vSphere | Mature, broadest ecosystem and feature set | Existing VMware estates, feature-rich environments |
| Nutanix AHV | Included with Nutanix, simpler licensing, tight HCI integration | VMware alternative, HCI-first deployments |
| Red Hat OpenShift Virtualization | Runs VMs and containers on one open platform | Container-and-VM estates, open-source strategy |
| Microsoft Hyper-V / Azure Local | Included with Windows Server, Azure hybrid integration | Microsoft-centric environments, Azure hybrid |
There is no single right answer. Staying on VMware, moving to Nutanix AHV, or running a mix can each be correct depending on the estate, the applications and the numbers. Proactive models the licensing and migration effort and lays out a costed path. A VMware migration, to Nutanix AHV, Hyper-V or another platform, is then run as a staged project so running workloads are not disrupted.
Why Converged and Hyperconverged? Why It Matters Now
- One system, not three silos: compute, storage and networking integrated, cutting complexity, tools and teams.
- Scale by node: incremental growth without re-architecture or forklift upgrades.
- Hypervisor choice: VMware, Nutanix AHV, Red Hat or Hyper-V, matched to your estate and licensing.
- A costed path off VMware: a migration-tested route to alternatives as Broadcom licensing reshapes costs.
- Simpler operations: one console and a small starting footprint, ideal for edge, VDI and lean teams.
- Built-in resilience: distributed storage, data services and snapshots, with no single SAN to fail.
For a decade the question was which SAN and which servers. Today, for a large share of virtualised workloads, the better question is whether you still need three separate tiers at all. HCI consolidates them, and for VDI, edge sites and general virtualisation it is usually simpler, faster to stand up and easier to run. The exceptions, very large or specialised workloads, still favour discrete compute and storage, and a good partner tells you which case you are in.
The VMware change has made this urgent. As a Dell Platinum Partner working across Nutanix, Red Hat and Microsoft as well as VMware, Proactive assesses the estate, models the licensing, and lays out a costed path, whether that is staying on VMware, moving to Nutanix AHV, or a mix, then migrates in stages without disrupting running workloads.
Converged and Hyperconverged Across India: Why the Estate Decides the Design
Indian enterprises arrive at HCI from different places. A GCC standardising a virtualisation platform across sites is a different problem from a manufacturer with VDI and edge needs, or a bank weighing the cost of renewing a large VMware estate against migrating it.
Workload mix, the size of the existing VMware footprint, edge and remote-site needs, and licensing budgets all shape the right answer here rather than on a datasheet. Proactive has designed and migrated converged and hyperconverged infrastructure across manufacturing, BFSI, healthcare, IT and ITeS and GCC environments in Delhi, Mumbai, Bengaluru, Pune and Hyderabad, matching the architecture and hypervisor to each estate.
Proactive Data Systems: The Partner That Designs, Migrates, and Runs
Choosing a platform is the easy part. Migrating a live virtual estate to it, without downtime and without surprises on licensing, is the part that rewards experience.
Proactive brings over three decades of enterprise infrastructure delivery, certified engineers and an ISO 9001:2015 quality system. As a Dell Platinum Partner working across Nutanix, VMware, Red Hat and Microsoft, we design and deliver converged and hyperconverged infrastructure on Dell, HPE and Nutanix, on the hypervisor that fits your estate and your budget.
Converged and hyperconverged infrastructure pulls together the rest of the data center stack. It works alongside Compute Solutions, Storage, AI Infrastructure, Data Protection and Cyber Recovery, and Data Center Networking, so the integrated system fits the wider estate.
From assessment and platform selection through migration, optimisation and ongoing support, backed by a 24/7 service desk, Proactive builds converged and hyperconverged infrastructure that simplifies operations today and keeps your options open tomorrow.
