    Where StorPool put its effort, 2016 to 2026

    Each square is one capability area in one year. The brighter it is, the more the area gained in the Virtualization Storage Ledger that year; 1, 2 and 3 mark that year's biggest pushes.

    Biggest pushes overall: Kubernetes and containers (+2), Hypervisor integration (+1.5), Data protection and DR (+1.5). Already strong in 2015: Hardware and deployment freedom, Resilience and HA, Performance and protocols.

    Top focus each year: 2023 Kubernetes and containers; 2025 Scale and topology; 2026 Hypervisor integration. 8 of 11 years show no gain in any area.

    Snapshot

    • Type: product
    • Owner: StorPool Storage, Sofia, Bulgaria, founded 2011; about 60 staff; self-funded and profitable per the vendor at IT Press Tour 67 (2026-04-08); no acquisition found
    • Licence: commercial, proprietary; quote only, billed on stored data per third-party listings (unverified); no free tier; StorPool One bundles KVM and storage since 2026-03-20
    • Latest release: 21.0.3306 (2026-09-11); major version 21 announced 2023-10-19
    • Support lifecycle: not published; one rolling 21.0 line since 2023 with live updates that do not interrupt service (vendor)
    • Next milestone: none published; the Disaster Recovery Engine has been in beta since 21.0.1212 (2025-03-05) with API v1.1 in 21.0.3305
    • Hypervisors: KVM through OpenStack, CloudStack, OpenNebula, OnApp and Proxmox VE (native client, solution provider listing 2026-04-27); VMware ESXi over iSCSI (KB); Oracle Virtualization is a vendor claim; Hyper-V, XCP-ng, AHV and KubeVirt not found
    • Tier: Software-defined storage
    • Archetype: Dependable builder
    • Evidence grade: B. The 21.0 release notes, hardware requirements, redundancy and encryption pages were read from the vendor knowledge base, and the Proxmox listing from the Proxmox press release. storpool.com did not render, so ownership, pricing and the versions before 21 come from trade press or were not found; the 2015 to 2022 steps are inferred.

    AI say-do, 2023 to 2026: 0 AI items announced; 0 GA, 0 still preview, 0 pending, 0 dropped. No AI item has been announced; the vendor names AI cloud customers only.

    StorPool has announced no AI feature. It lists GPU cloud operators among its customers, but nothing in the release notes serves AI workloads differently from any other block workload, and agents get a REST API without an MCP server.

    Reading

    StorPool scores as mature block storage for KVM clouds whose lines have moved little since 2023 apart from erasure coding, cross-cluster volume migration and the Proxmox VE listing. Resilience stays at 3.5 because no stretched or metro mode was found, and security sits at 1.5 because the design leaves the storage network unencrypted and no RBAC or external key management is documented. Hardware freedom is the strongest line, with mixed drives on any x86 server and Arm arriving. A buyer should get the support lifecycle, the price and the VMware support statement in writing, because none of the three is public and the vendor site could not be read for this edition.

    Open questions and items to re-score

    • First release date and the dates of versions 18 to 20; the production-ready year is a judgement.
    • Support lifecycle and pricing: nothing public; third-party listings describe quote-only, usage-based pricing.
    • Whether the NVMe target service is NVMe/TCP, and whether VMware ESXi is supported beyond iSCSI.
    • Hyper-V, XCP-ng, AHV and KubeVirt support: named on a homepage summary that did not render; unverified.
    • Whether the Disaster Recovery Engine is GA; beta since 2025-03-05, API v1.1 in 2026-07.
    • The Kubernetes driver's release date and its RWX and KubeVirt behaviour.
