What the Ledger says
Portworx is the strongest Kubernetes-native entry in this group on resilience, DR and Kubernetes depth, and since 3.4.0 it covers what a KubeVirt VM needs: shared RWX block for live migration and zero-RPO synchronous DR, both GA. Hypervisor integration is capped at 3.5 because only KubeVirt platforms are served, and the data services line stays at 3 because there is no deduplication, inline compression or erasure coding. The commercial side is where a buyer should look: the free tier is gone, most release lines are supported for six months, and several headline features need a Pure FlashArray behind the cluster. Check which release line is the Extended Maintenance Release before you deploy.
Portworx's AI story is Pure1's: a GA Copilot that answers questions about Portworx telemetry and an MCP connection that is still a plan. The storage itself has no GPU or AI-workload feature verified, and agents drive it through its CRDs and API like any other Kubernetes resource.
Capability by area
Buying, lock-in and release record
Buying and licence (commercial risk)(lower is better)
- Price and licence volatility3
- Free tier removed 2025-02-10; new PX-KV and Edge SKUs; no public price list
- Purchase constraints3.5
- Subscription only, quote based; 30-day trial is the only free option
- Channel and access2
- Public docs and operator images; support tied to subscription; partner terms not found
- Owner stability1.5
- Owned by a listed company since 2020; rebranded Everpure in 2026 with a strategy shift toward data management
- Cost of staying supported3.5
- Most lines expire after six months; an EMR line must be chosen to get 18 months
Technical lock-in(lower is better)
- Formats1.5
- Standard PVCs; KubeVirt disks are raw or qcow2 images on PVCs
- Export path2
- CSI snapshots, CloudSnap to object stores and Portworx Backup; no export of VM disks to a non-Kubernetes target documented
- Stack coupling3.5
- Needs a Kubernetes distribution and the Portworx data plane; KubeVirt platforms only
- Hardware / cloud coupling2
- Software-defined on any drives, cloud drives or vSphere; ActiveCluster, cross-array snapshots and realms need Pure FlashArray
- Skills and tooling coupling3
- Kubernetes plus pxctl and Portworx-specific tooling
Release credibility
- Cadence4
- A feature release every three to six months (3.5 in 2025-11, 3.6 in 2026-04, 3.7 in 2026-09) with a published support table
- Roadmap transparency2.5
- Public release notes and forum posts; no public dated feature roadmap
- Say-do3.5
- KubeVirt RWX block and sync DR announced 2025-04, early access 2025-06, GA 2025-09; Pure Fusion integration slipped past its H1 FY27 target and MCP connectivity is still planned
- Velocity4
- Several capabilities per feature release
- Lifecycle stability2
- Six months of support per non-EMR line and 18 months for one EMR a year; Essentials removed and capped at 3.2.2.1
