3PAR (HPE 3PAR StoreServ)

3PAR is an enterprise storage platform, now part of Hewlett Packard Enterprise (HPE acquired 3PAR in 2010), that powers mission-critical applications with HPE 3PAR StoreServ and Primera arrays. For developers and automation engineers, 3PAR exposes the HPE 3PAR Web Services API (WSAPI) — a REST interface that manages storage provisioning, virtual volumes, hosts, ports, CPGs, snapshots, and remote copy on 3PAR/Primera/Alletra arrays, offering a more flexible and programmable alternative to the 3PAR Command Line Interface. HPE publishes first-party client libraries (Python, Ruby, PowerShell) plus Ansible, Puppet, Chef, OpenStack Cinder, and Docker volume integrations against WSAPI. This profile was surfaced as a venture-portfolio lead (Mayfield, Menlo Ventures backed the original 3PAR before its IPO and HP acquisition) and enriched from HPE's public developer surface.

3PAR (HPE 3PAR StoreServ) publishes 1 API on the APIs.io network. Tagged areas include Company, Storage, Enterprise Storage, Infrastructure, and Data Management.

3PAR (HPE 3PAR StoreServ)’s developer surface includes documentation, API reference, support, and 4 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/3par: open an issue to ask a question, or submit a pull request to add artifacts.
