If you are an IT Architect, Admin, or Site Reliability Engineer (SRE) managing critical workloads on VMware, your 2026 likely began with a singular headache: The Renewal. Since the Broadcom acquisition, the “Broadcom Tax” has become a well-known cost. Between the elimination of perpetual licenses, mandatory shifts to massive subscription bundles, and aggressive 72-core minimums, “standardizing on VMware” has become an exercise in forced over-provisioning.
But there is a risk greater than the price hike: the cost of application downtime.
The “VM Restart” Fallacy: Why VMware HA Isn’t True High Availability
For years, the industry has mistaken “VMware HA” for true High Availability. If a host fails, VMware restarts the VM on another server. While this is a fast reboot, it is not High Availability.
VMware HA only monitors the physical server’s “heartbeat” to determine whether the host is operational or not. It is blind to the world inside the VM. It cannot detect a database that is hung, application services that are deadlocked, or storage that is unavailable.
Today’s mission-critical ecosystems—SAP HANA, SQL Server, Oracle, and AI-driven GPU systems—require more than a “power cycle” approach. They require application-level protection.
SIOS LifeKeeper: True HA via Application-Aware Intelligence
SIOS LifeKeeper provides visibility across your application environment: network, storage, OS, and database layers. It ensures rapid, Application-Aware Failover in compliance with application-specific best practices to deliver reliable uptime, not just a fast reboot.
While Broadcom’s licensing model effectively taxes your growth and tethers you to their ecosystem, SIOS offers true architectural freedom. Our platform-agnostic licensing allows you to migrate workloads to AWS, Azure, or alternative hypervisors without losing your HA protection. With SIOS, you aren’t just buying software; you’re securing an exit strategy from vendor lock-in.
Slashing TCO After VMware Pricing Changes: Protect the App, Not the Hypervisor
Broadcom not only requires you to buy subscription licenses, but it often requires you to upgrade your entire VMware stack or purchase bloated subscription tiers just to access the HA features needed for a single Tier-1 application.
Why upgrade your entire infrastructure license to protect one SQL Server or SAP instance? SIOS provides enterprise-class HA that lives with your application, regardless of which VMware “bundle” the Broadcom mandate. SIOS also gives you the flexibility to purchase subscription or perpetual licenses.
Eliminate the Cost and Complexity of SANs and vSAN Dependencies
Many new VMware bundles push customers toward vSAN, in environments where every millisecond counts, SIOS DataKeeper allows you to build clusters using local, high-performance NVMe storage. You get the protection of a cluster without the proprietary complexity or the “storage tax” of a virtual SAN.
SIOS delivers the capabilities—such as advanced data replication—that VMware typically gates behind its most expensive tiers. By decoupling HA from the hypervisor, you can maintain world-class uptime on more economical VMware licenses, potentially saving six or seven figures on your next renewal.
VMware HA vs. SIOS LifeKeeper and DataKeeper
| Feature | VMware HA (vSphere Foundation) | SIOS LifeKeeper & DataKeeper |
|---|---|---|
| Failover Trigger | Host/Hardware failure only. | Application, OS, Storage, or Network failure. |
| App Intelligence | None. It’s a “black box” restart. | Recovery Kits for SAP, SQL, Oracle, & more. |
| Cloud Flexibility | Requires specific VMware Cloud stacks. | Native in AWS, Azure, GCP, or Hybrid. |
| Storage Model | Dependent on vSAN or Shared Storage. | SANless Clusters via local NVMe/SSD. |
| Licensing | Complex, Core-based, Bundle-heavy. | Predictable, portable, and application-focused. Your choice of perpetual or subscription. |
Reclaim Your Infrastructure Freedom with Application-Level High Availability
SIOS gives you the flexibility to maintain high availability on your own terms while you evaluate your long-term relationship with Broadcom.
By choosing SIOS, you gain the freedom to move workloads between VMware, Nutanix, or the Public Cloud without rewriting scripts or retraining your team. You get uptime determined by the health of the application environment, not just the server’s power light.
If your upcoming renewal feels like a dead end, it’s time to move your High Availability out of the hypervisor and into the application layer.
