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.

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.

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.
