Eight free buyer side tools for the IBM estate. PVU and Red Hat calculators, ILMT sub capacity readiness, ELA true up math, audit defense checklist, and a mainframe MSU model.
Eight free tools across the IBM estate, from PVU and Red Hat sizing to ILMT readiness, ELA true ups, audit defense, and mainframe MSU math. Each encodes the Redress engagement file across IBM Passport Advantage, Cloud Pak, and ELA deals. Pick the tool that matches your live IBM decision and run the math before the meeting.

IBM PVU products are priced by processor value units per core on the physical host. Without a compliant ILMT deployment, IBM bills every PVU product at full capacity, counting every core in the cluster rather than the cores the workload actually uses.
ILMT is the only tool IBM accepts as proof of sub capacity. If it is missing, late, or stopped reporting, the discount disappears and the cluster bills in full.
| Basis | Full capacity (no ILMT) | Sub capacity (ILMT compliant) |
|---|---|---|
| Cores counted | Every core in the physical host or cluster | Only the virtual cores assigned to the workload |
| ILMT requirement | None, but you pay for all cores | ILMT installed, reporting every 30 minutes, quarterly reports kept |
| 32 core host, 4 vCPU workload | 32 cores licensed | 4 cores licensed |
| Typical overpay | Baseline | Often 60 to 85 percent lower |
| Audit posture | Compliant by default, expensive | Compliant only if ILMT evidence is clean |
Sub capacity pricing collapses to full capacity in three common cases. ILMT was installed late, so no continuous record exists for prior quarters. ILMT stopped reporting on some hosts and nobody noticed. Or the quarterly PVU reports were never generated and signed. The readiness check scores all three before IBM does.
An IBM Enterprise License Agreement fixes a price for a basket of products over a term, usually three years. The true up at anniversary is the largest single buyer side leverage point on the contract.
A true up bill lands when measured deployment exceeds the licensed basket at the anniversary. The fix is to count deployment against entitlement every quarter, not once a year.
The breakeven point is the deployment level at which the ELA fixed fee costs less than the equivalent Passport Advantage licenses plus support. Above breakeven, renew the ELA. Below it, exit to discrete licensing at certification.
Most ELAs do not break even on the second term. The buyer recommitted at a deployment forecast that overshot actual use. Model the true up eighteen months out, not at the anniversary letter, and the renewal reshapes itself.
Run the ILMT sub capacity readiness check first if you license PVU products on virtualized hosts. Without a compliant ILMT deployment IBM bills sub capacity workloads at full capacity, which is the single most expensive default in the IBM catalogue. After ILMT, run the PVU calculator to size your actual entitlement, then the audit readiness assessment to score exposure.
The PVU calculator is accurate to within roughly 5 to 10 percent of contract pricing on standard configurations. It encodes IBM's published PVU table per processor model and the sub capacity rules ILMT enforces. Custom bundles, Cloud Pak VPC conversions, and grandfathered Passport Advantage terms still need human review.
No. The calculator output is buyer side benchmark data. Sharing your modeled entitlement or true up exposure with IBM removes your information advantage before the negotiation starts. Run the math internally, build the position, then engage IBM with anchored numbers.
Yes. The Red Hat subscription calculator models socket pair and core based subscriptions for RHEL, OpenShift, and Ansible. IBM now sells Red Hat through Passport Advantage and as Cloud Pak entitlements, so the tool reconciles standalone Red Hat subscriptions against Cloud Pak VPC bundling.
Yes. Every Redress IBM tool is free to use. We do not gate them behind a paywall. Some assessments ask for a corporate email to send the scored result. None require payment.
Quarterly, and within 30 days of any IBM Passport Advantage price change or sub capacity policy update. PVU per core values, Cloud Pak VPC ratios, and Red Hat subscription terms are the fields we track most closely.
PVU prices a product by processor value units per core on the underlying hardware, while VPC prices Cloud Paks by virtual processor core regardless of host model. The PVU calculator handles legacy Passport Advantage products; Cloud Pak estates use the VPC math, which the same tool converts so you can compare the two entitlement models side by side.
We run the buyer side process end to end. Morten Andersen and the IBM practice run the entitlement math internally, benchmark your PVU and ELA pricing against our engagement file, build the negotiation and audit defense strategy, and sit at the table for the final round. We are not an IBM partner.
Tool output is the anchor. Walk into the IBM meeting with a PVU number you trust and the negotiation reshapes itself.
