Broadcom moved vSAN to per tebibyte capacity licensing inside VVF and VCF, which changed the HCI cost equation and reopened the Nutanix comparison for 2026.

Key takeaways

  • vSAN is now capacity priced: licensing runs per tebibyte, with an allowance bundled per core in VVF and a larger one in VCF.
  • The allowance misleads: the bundled capacity covers small footprints; real HCI estates buy paid capacity on top.
  • TCO must be recut: per tebibyte pricing punishes storage heavy clusters that the old per CPU model tolerated.
  • Nutanix is the anchor: a real alternative evaluation moves Broadcom pricing 25 percent or more at renewal.
  • Hardware refresh is the window: HCI decisions made inside a refresh cycle avoid paying twice.
  • Three year caps or nothing: subscription HCI without price protection is an uncapped cost curve.

How is vSAN licensed under Broadcom in 2026?

vSAN licenses per tebibyte of raw capacity, sold standalone or as an allowance inside VVF and VCF, as described on the VMware vSAN product page. The per CPU socket license is gone with the rest of the perpetual portfolio.

  • VVF allowance: a small per core capacity entitlement, sized for modest footprints.
  • VCF allowance: a larger per core entitlement reflecting the private cloud positioning.
  • Paid capacity: everything above the allowance bills per tebibyte per year.

Measure raw capacity per cluster before any quote conversation. The allowance math decides whether your estate is effectively included or materially additional.

What does HCI total cost look like under capacity pricing?

Capacity pricing shifts cost from compute density to storage density, so storage heavy clusters that were cheap per socket became expensive per tebibyte under both VVF and VCF. The TCO model has to be rebuilt, not indexed.

Where estates overpay first

Cold and backup data sitting on vSAN datastores is the first overpayment we find. Per tebibyte pricing makes vSAN a premium tier; treat it as one and move cold data off it.

How should you evaluate Nutanix and other HCI alternatives?

Evaluate alternatives on a like for like workload basis with migration cost included, because the license delta only matters net of the move. Nutanix is the primary anchor, with Azure Stack HCI and external array plus vSphere as secondary paths.

The evaluation that changes pricing

  • Named clusters: pick 2 or 3 real clusters as the migration candidates, not a hypothetical estate.
  • Full cost model: licenses, hardware, migration labor, and retraining over 5 years.
  • Executive sponsorship: a signed off assessment moves Broadcom; a slide does not.

In our 2024 to 2025 renewals, a documented evaluation moved Broadcom HCI pricing 25 to 40 percent even where the buyer ultimately stayed.

When should you stay on vSAN and when should you move?

Stay when your storage profile fits inside or near the bundled allowance and the operational integration pays its way; move when storage density drives the bill and a refresh window is open. The wrong answer is deciding by default at renewal pressure.

  • Stay signals: compute dense clusters, allowance coverage, deep vSphere operational dependence.
  • Move signals: storage heavy growth, an open hardware refresh, team capability on the alternative.
  • Hybrid signal: keep vSAN for hot tiers, externalize cold data, and shrink the licensed capacity.

Whatever the direction, write price caps and renewal protection into the subscription. An uncapped per tebibyte rate on growing data is a structural escalator.

Where the common advice on vSAN HCI evaluation is wrong

The standard advice frames the 2026 decision as VMware versus Nutanix, a platform bake off. We disagree with the frame. In roughly 9 of the 15 plus HCI estates Morten Andersen reviewed in 2024 to 2025, the bigger lever was inside the estate: cold data sitting on premium vSAN capacity and clusters that a refresh cycle could consolidate. Rebalancing storage tiers cut licensed tebibytes 20 to 35 percent before any vendor conversation. The buyer side move is to shrink the licensed footprint first, then run the platform comparison on the smaller estate. Migrating an unoptimized estate just moves the overspend to a new logo.

How to use these numbers

Treat the ranges as negotiation benchmarks, not promises. Your estate sets the baseline; the engagement file tells you what disciplined buyers achieved against the same vendor playbook.

Per tebibyte pricing made vSAN a premium storage tier. Buyers who keep treating it as default storage fund the difference.

What to do next

The moves below turn this analysis into a lower invoice at the next renewal.

A sequence you can run this quarter

  1. Measure raw vSAN capacity per cluster and compare it against the VVF or VCF allowance math.
  2. Identify cold and backup data on vSAN datastores and model moving it to cheaper tiers.
  3. Consolidate clusters where the hardware refresh cycle allows.
  4. Run a named cluster Nutanix evaluation with a full 5 year cost model.
  5. Demand per tebibyte rate caps and renewal protection in any subscription.
  6. Decide stay, move, or hybrid on the optimized estate, not the current one.

Frequently asked questions

How is vSAN licensed in 2026?

vSAN licenses per tebibyte of raw capacity. VVF includes a small per core capacity allowance and VCF a larger one; capacity above the allowance is bought per tebibyte per year. The old per CPU socket licensing is gone.

Did vSAN get more expensive under Broadcom?

For storage heavy clusters, usually yes: we measured 30 to 80 percent increases versus the per CPU era. Compute dense clusters with modest storage can land flat or better because of the bundled allowance, which is why per cluster math is essential.

Is the vSAN capacity included in VVF enough?

Only for modest footprints. The VVF allowance covers small datastores; production HCI estates with dense storage buy paid capacity on top. Run the allowance math per cluster before treating vSAN as included.

Does a Nutanix evaluation actually move Broadcom pricing?

Yes. In our 2024 to 2025 renewals a documented evaluation with named clusters, a full cost model, and executive sponsorship moved pricing 25 to 40 percent, even where the buyer stayed. Undocumented threats moved nothing.

What is the cheapest immediate vSAN optimization?

Move cold and backup data off vSAN datastores. Capacity licensing prices every tebibyte, so externalizing data that does not need HCI performance cut licensed capacity 20 to 35 percent in the estates we reviewed.

When is the right time to decide on HCI direction?

Inside a hardware refresh window. Deciding at renewal pressure without a refresh open means paying for hardware and licenses twice; aligning the two decisions avoided 20 to 30 percent in stranded spend in our engagements.

Should we move everything off vSAN?

Rarely. The defensible pattern is hybrid: keep vSAN for hot tiers where the operational integration pays, externalize cold data, consolidate clusters, and shrink the licensed footprint before any migration decision.

What contract terms matter on a vSAN subscription?

Per tebibyte rate caps, renewal uplift protection, and allowance definitions frozen in the order form. Data grows; an uncapped capacity rate is a built in escalator on that growth.
