Credibility: 15.5 / 25

Criterion	Score	Basis
Cadence	4	A dated minor every two to three months from 3.8.1 (2024-04-24) to 3.20.1 (2026-08-09); STS and LTS streams described without a calendar
Roadmap transparency	2.5	Public release notes with known and fixed issues; no roadmap
Say-do	3	Few forward announcements; Ubuntu and Okta shipped as announced; cross-cluster DMS clones have stayed in preview since 3.13.1 and the Proxmox plug-in is still Tech Preview
Velocity	3.5	Security and operations steps in most releases; protocol and DR breadth grows slowly
Lifecycle stability	2.5	Support covers the latest release and the two before it, which is six to nine months on the STS stream; LTS durations not published; upgrades from the previous three lines

Commercial risk: 11.5 / 25 (lower is better)

Criterion	Score	Basis
Price and licence volatility	1.5	Public per-TB price; no history of changes found
Purchase constraints	2.5	Subscription per TB with support bundled; no perpetual or free option
Channel and access	2.5	Public docs; packages from a vendor repository; partner terms not found
Owner stability	2.5	Private, venture and strategic backed since 2016; a new AI product line in 2026; no acquisition found
Cost of staying supported	2.5	Must stay within the latest three releases unless on the LTS stream

Technical lock-in: 8.5 / 25 (lower is better)

Criterion	Score	Basis
Formats	2	Standard NVMe/TCP namespaces any Linux or ESXi initiator can mount; proprietary on-disk layout
Export path	1.5	Any host can read the volumes; no export tool needed
Stack coupling	1.5	Works under VMware, Proxmox VE, OpenStack and Kubernetes; needs dedicated NVMe storage servers
Hardware / cloud coupling	1.5	Standard NVMe servers on RHEL family or Ubuntu 24.04; optional AWS and Azure
Skills and tooling coupling	2	lbcli and Ansible on top of standard NVMe/TCP

Integrator fit: 11.0 / 20

Criterion	Score	Basis
Partner programme openness	2.5	Direct plus OEM and service provider routes; programme terms not found
Multi-tenancy and self-service	3.5	Projects, OpenStack multi-tenancy and QoS, in-band authentication per host
API and infrastructure-as-code	3	REST API, lbcli and Ansible roles; Terraform provider not found
Skills and certification	2	Not found

AI leverage: 2.0 / 20

How the product uses AI, scored per year like capability. Only GA counts.

Criterion	2019	2022	Today	Latest step
AI workload infrastructure	0	0	0	2019: None
AI platform stack	0	0	0	2019: None
AI-assisted operations	0	0	0.5	2025: 3.14.1: experimental lbcli ask (preview, half step); later status not found
Agent openness	1.5	1.5	1.5	2019: REST API and lbcli; no MCP server

Year by year: 2019: 1.5 · 2020: 1.5 · 2021: 1.5 · 2022: 1.5 · 2023: 1.5 · 2024: 1.5 · 2025: 2 · 2026: 2

AI say-do, 2023 to 2026: 2 AI items announced; 0 GA, 1 still preview, 1 pending, 0 dropped. lbcli ask has been experimental since 3.14.1; Inferra was announced on 2026-09-09 as a separate product.

Lightbits sells block storage to AI clouds but has no AI feature of its own in GA: the lbcli ask assistant has been experimental since April 2025 and Inferra, the KV cache engine announced in September 2026, is a separate product. Agents get a documented REST API and nothing more.

Reading

Lightbits is the most regular shipper in this group, with a dated release every two to three months and a public price, and its security line has risen fastest since 2024 with encryption at rest, key rotation, in-band authentication and identity federation. The limits are breadth: one protocol, no stretched cluster, no DR orchestration, and a hypervisor list where only ESXi and OpenStack are GA while Proxmox VE sits in Tech Preview. The scores hold the data services line at 3 because inline compression was not verified in the release notes. A buyer should ask for the LTS stream's version and support window in writing, because the support guide only covers the latest three releases.

Open questions and items to re-score

The LTS label on 3.18.2 came from a scope note; the 3.18.2 release notes and the support guide do not say which version is LTS or how long LTS lasts. The 3.18.2 patch (2026-06-17) shipping after 3.19.1 (2026-05-18) suggests a maintained line, but that is an inference.
Inline compression and deduplication: not read in the release notes.
ESXi 8 support and the VMware HCL entry; the vendor page names only 7.0U3 as the initiator minimum.
The Proxmox VE plug-in release date and when it leaves Tech Preview; the solutions page lists Proxmox VE 9.x tested on 9.2.
Whether the Data Mobility Service's cross-cluster clones left preview after 3.13.1.
Releases 3.1 to 3.7, 3.11 and 3.18.3 to 3.18.4 were not read; the 3.4.1 release date is not stated in its notes.
