Third-Party Maintenance vs OEM Support: An Honest Comparison

Where independent TPM beats HPE Tech Care and Dell ProSupport on cost, SLA and end-of-life cover — and the one thing OEM support still does that TPM cannot. Model your own saving with the live calculator below.

Renewing HPE Tech Care or Dell ProSupport on kit that already runs reliably is one of the easiest ways to overspend in the data centre. Third-party maintenance (TPM) covers the same hardware for far less, matches or beats OEM response times, and keeps running long after the manufacturer forces a refresh. But it is a hardware service — so the honest picture includes where OEM programmes still hold an edge. This page compares the two fairly, then lets you model the exact difference for your estate.

Figures are indicative estimates shown as a range, based on the Gartner 50–70% saving band applied to an example spend, and confirmed by a free Servnet support audit — not a quotation. Third-party maintenance covers hardware break-fix and defers refresh; it does not supply software or firmware security patches.

Cost and SLA: where TPM clearly wins

On like-for-like hardware cover, independent TPM undercuts renewal pricing on HPE Tech Care and Dell ProSupport substantially — and locks the rate for the term rather than applying compounding renewal uplifts. On service levels it matches or beats the OEM: Servnet can mirror HPE Tech Care Essential (24×7, 4-hour on-site) or Critical (6-hour call-to-repair) and Dell ProSupport Plus response windows, using certified engineers and pre-staged UK parts. The calculator above turns that into a real figure for your ProLiant, PowerEdge or storage estate.

Coverage: hardware vs the OEM software bundle

This is the honest part. TPM covers hardware — diagnosis, field-replaceable units, on-site engineering. HPE Tech Care and Dell ProSupport bundle more: entitled firmware, the Service Pack for ProLiant, OS and select-software support, plus proactive telemetry like Dell SupportAssist. Crucially, HPE gates firmware and security patches behind an active entitlement, so leaving OEM support can cut off patch access on ProLiant and Alletra. If firmware security patching is contractual for you, factor that in — or keep a thin OEM entitlement alongside TPM.

EOSL and flexibility: no forced refresh

OEM support has a cliff. Once HPE or Dell publishes an end-of-service-life date, Tech Care and ProSupport are withdrawn and you are pushed toward a new PowerEdge, ProLiant or PowerStore generation. TPM has no such date — Servnet holds parts and expertise for legacy platforms for years beyond EOSL, letting you sweat proven assets on your timetable. It also consolidates a mixed HPE, Dell, Cisco and NetApp estate under one contract, one SLA and one invoice, instead of a separate OEM agreement per brand.

FAQs

Is third-party maintenance really cheaper than HPE Tech Care or Dell ProSupport?

Yes — on equivalent hardware cover, independent TPM consistently prices below OEM renewal rates, and the gap widens over a multi-year term because TPM avoids the compounding renewal uplifts common to Tech Care and ProSupport. The exact difference depends on make, model, age and SLA tier, which is why the calculator on this page models it live against your own estate rather than quoting a fixed percentage.

What does OEM support cover that TPM does not?

HPE Tech Care and Dell ProSupport bundle software with the hardware: entitled firmware and the Service Pack for ProLiant, OS and select-application support, and proactive tools like Dell SupportAssist. HPE restricts firmware and security patches to accounts with an active entitlement. TPM is a hardware service, so if contractual firmware security patching matters to you, keep a thin OEM entitlement alongside your TPM contract.

Does switching to TPM mean I have to replace hardware at end-of-service-life?

No — that is one of TPM's biggest advantages over OEM support. When HPE or Dell reaches an EOSL date, Tech Care and ProSupport are withdrawn and you are pushed to refresh. Servnet keeps parts and certified engineers for legacy ProLiant, PowerEdge and storage platforms for years afterward, so you decide when to refresh on cost and risk grounds — not on the manufacturer's calendar.

How we work these figures out

Saving band: Gartner, "Market Guide for Data Center and Network Third-Party Hardware Maintenance", 29 Aug 2019 (ID G00414695) — TPM contracts save 50–70% off OEM support NET prices. IDC (2022) separately reports savings of up to ~50% vs OEM. Reports are dated; net-price basis (not off-list).
