Source-derived summary

HP Serviceguard, formerly known as MC/ServiceGuard, is a high-availability cluster software produced by HP that runs on HP-UX and Linux.

Serviceguard has existed since 1990, which HP claims to have been the first high availability solution for UNIX. A Linux port called SG/LX has existed since 1999, but was briefly suspended and then reintroduced in June 2012.

Editorial summary

Begin with the source’s own compact description: “HP Serviceguard” is high-availability cluster software. The dossier treats that line as a proposition to test through Serviceguard, high-availability and cluster, not as a finished interpretation.

Editorial reviewA practical orientation to terminology and classification, particularly when read beside dated observations, specimens or technical literature. The current lead gives the account dated anchors—1990, 1999, 2012—that can be checked directly. The selected authority fields contribute no independent date. For this dossier, Serviceguard, high-availability and cluster is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “high-availability cluster software” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Aug 4, 2025. The linked authority identifier is Q1723757. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1990, 1999 and 2012.

Critical limits

Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
