Hyperconverged infrastructure sized for the licence maths, not the brochure

Hyperconverged infrastructure for Canadian data centres, designed around what the licensing actually costs per core.

THE WORK

Hyperconverged infrastructure, three pillars, one operator.

One Canadian team sizes the nodes, moves the workloads, and owns the renewal date.

  1. 1

    Size it against the licence

    Licensing is per physical core with a floor of sixteen cores per CPU, so a twelve-core socket bills as sixteen (source: Broadcom, 2026). You pay for that floor whether the silicon has those cores or not, which makes socket choice a licensing decision before it is an engineering one.

  2. 2

    Move without a maintenance weekend

    Workload by workload, with the old estate still running until it isn't needed. Each wave stays reversible until its tests pass, so nobody has to book a Saturday and hope.

  3. 3

    Watch the storage meter

    Capacity is metered per core now: a vSphere Foundation core entitles you to a quarter of a TiB of vSAN, a Cloud Foundation core to a full TiB (source: Broadcom, 2026). The shape of a node sets your storage ceiling.

THE PROOF

Built to last. Evidence over promises.

Perpetual licences are gone, storage is metered per core, and a late renewal carries a 20% penalty with no grace period.

IN PRODUCTION

A Canadian cluster that halved its cores.

Our renewal quote tripled and the reseller's answer was to buy the bigger bundle. SMEnode redesigned the cluster around the core count: fewer, denser nodes, storage rebalanced to what the licence entitled us to. Same usable capacity, half the licensed cores. The migration took a quarter and nobody booked a weekend.

THE DEEP DIVE

Hyperconverged infrastructure in Canada, made real.

Most of what's written about this technology describes what it is. Almost none of it tells you what now decides the cost.

Cores and capacity stopped being separate decisions.

Licensing is per physical core with a floor of sixteen per socket, so a twelve-core CPU bills as sixteen and a socket choice becomes a licensing choice. Storage went the same way: a vSphere Foundation core entitles you to a quarter of a TiB of vSAN, a Cloud Foundation core to a full TiB (source: Broadcom knowledge base, core counting for VCF, VVF and vSAN). Put those together and node shape sets your ceiling. Two clusters delivering identical usable capacity, one wide and shallow and one narrow and deep, can differ by a large multiple in annual cost.

We size before we shop.

That means counting the workloads that need to live on this cluster, measuring real IOPS and working set rather than allocated disk, then solving for the cheapest legal combination of sockets, cores and capacity that carries them with a node to spare. The usual finding is that the estate is licensed for the storage it was allocated instead of the storage it uses, and that gap is where the money is.

The vendor question comes last, and it's smaller than it looks.

We build both VMware and Nutanix across Canadian estates, and the honest tiebreaker is usually your core-to-capacity ratio and what your team can operate at 2am. Worth knowing while you compare: Gartner stopped publishing the Magic Quadrant for Hyperconverged Infrastructure and folded the market into the Magic Quadrant for Distributed Hybrid Infrastructure, so the best-vendor lists still circulating answer a question the analysts stopped asking.

THE METHOD

How our HCI migration and sizing work runs.

Four steps, and step 01 is counting rather than quoting. Before anybody sizes a node we want the workload inventory with real numbers attached: peak IOPS, actual working set, memory in use rather than memory assigned, and which of these systems could leave the cluster entirely. That last column is usually the cheapest line in the whole project, because a workload that moves elsewhere is a workload you never licence again.

  1. Step 01

    Inventory and measure

    Every workload with real IOPS, working set and memory in use, plus an honest column for the ones that don't belong on this cluster at all.

  2. Step 02

    Solve the sizing

    Sockets, cores and capacity worked as one problem against the licence terms, with a node of headroom and a written comparison of the wide and the dense builds.

  3. Step 03

    Migrate in waves

    Workload by workload with the old estate still serving, each wave reversible until its tests pass, and no dependency on a maintenance weekend nobody wants to own.

  4. Step 04

    Hand over the renewal

    The capacity meter watched against entitlement, a diary entry well before the renewal date, and your Canadian team trained on what changes the bill.

QUESTIONS

Hyperconverged infrastructure questions, answered straight.

Answers first, including the sizing arithmetic and the analyst report that no longer exists. An architect takes the call, not a salesperson.

Where the storage lives. A three-tier estate keeps compute, a storage network and an array as separate things you buy, cable and staff separately. Hyperconverged puts storage on the same nodes as compute and pools it in software, so you scale by adding a node. The trade is flexibility for simplicity: three-tier lets you grow storage without buying compute, which still matters if your data grows far faster than your processing.

We build both, so the answer isn't ours to sell you. It usually turns on your core-to-capacity ratio, because the per-core entitlements reward some shapes and punish others, and on what your team already operates confidently. Storage-heavy estates with modest compute tend to look worse under per-core storage metering. If you're mid-renewal with a tripled quote, get the sizing redone before you accept either the bundle or the migration.

Solve cores and capacity together, never in sequence. Count real workload demand rather than allocated disk, apply the sixteen-core-per-socket floor, then check the storage entitlement your licence tier actually grants per core. Add one node of headroom, not thirty per cent of everything. Then price the wide build against the dense build, because they rarely cost the same even when they perform the same.

No, and it's mostly history now. Converged infrastructure meant pre-validated racks of separate compute, network and storage sold as one part number, with the pieces still distinct inside. Hyperconverged collapses the storage into the compute nodes and does it in software. Search interest in the older term has fallen by two thirds in a year, which is a fair reflection of how often anyone buys one.

It costs you. Renewal terms carry a 20% penalty for late renewal with no grace period, and the bundles charge for components such as NSX whether you run them or not (sources: Redress Compliance, VMware Migration Hub). Perpetual licences are gone, so there's no version to sit on while you argue. We put the date in a diary months ahead and name the person who owns it.

When your storage grows much faster than your compute, since paying for cores to hold data is the expensive way to buy a disk. When the estate is a year from a hardware refresh and the current kit is fine, because a migration timed to the refresh costs far less. And when nobody will own the renewal date, as an unwatched capacity meter is how a good design turns into a bad invoice.
