Authoritative source data
Every milestone date is sourced from the OEM's published End-of-Sale / End-of-Life bulletins. Source URLs are recorded per OEM. We do not extrapolate dates — if a date is unpublished, the entry is omitted.

OEM EOSL Calendar — every milestone date, every active model
Curated End-of-Sale, End-of-Software-Maintenance, End-of-Vulnerability-Maintenance, and Last-Date-of-Support dates across nine OEMs in the 2023–2031 lifecycle window. Each model annotated with WUC commentary on TPM economics and refresh-vs-extend trade-offs.

Methodology
How this calendar is built — and why it stays accurate.
Four-milestone schema
Each entry records End of Sale (EoS), End of Software Maintenance (EoSWM), End of Vulnerability/Security Maintenance (EoVSM), and Last Date of Support (LDoS). This matches Cisco's lifecycle terminology and maps cleanly to Dell, HPE, NetApp, and other OEM equivalents.
WUC commentary, not just dates
Reference calendars exist on every OEM's site. What's missing in those is independent commentary on TPM economics per platform — when SmartNet / ProSupport / SupportEdge renewal still makes sense versus when TPM dominates. That commentary is the value-add here.
Quarterly refresh cadence
OEMs publish EOL bulletins continuously. We refresh this calendar quarterly — checking each OEM's lifecycle page, integrating new bulletins, flagging date extensions. The `last_updated` value on each per-OEM page is honest.
How to read this
The four dates, in plain language.
End of Sale (EoS)
Last day the OEM accepts new orders. Existing units remain fully supported through subsequent milestones. EoS is the procurement deadline, not the support deadline.
End of Software Maintenance (EoSWM)
Last day the OEM releases bug-fix software updates. After this date, you keep your installed software but no new releases. Critical for shops with active feature roadmap consumption.
End of Vuln/Sec Maintenance (EoVSM)
Last day the OEM releases security patches for known vulnerabilities. After this date, new CVE disclosures are not patched. This is the compliance-critical milestone for PCI/HIPAA/SOX environments.
Last Date of Support (LDoS)
Final day the OEM accepts support cases. After LDoS, no OEM engagement is possible; the platform is third-party-maintenance or replacement only. WUC TPM covers all platforms below indefinitely post-LDoS.
