Runs systems at their EOSL date that work fine. Pushed to refresh — but budget is tight and the business case for 'it still runs' is missing.

End of Life.
The practical guide for IT leaders and datacenter managers: how to cleanly evaluate, safely extend or deliberately replace server, storage and network hardware after vendor support ends — with a transparent risk score, NIS2/BSI context and budget models.

The strongest evidence
If 6 years works for AWS, why not for you?
Between 2022 and 2024 every major cloud operator extended the accounting useful life of their servers — and certified it to their auditors. The very hardware generations vendors recommend replacing run a planned six years there.
- EOSL is a contractual, not a wear-out date — the vendor ends sales & support, not the hardware its operation.
- Large drive fleets show just ~1.57% annual failure in 2024 — risk rises gradually after year 5, not as a cliff at the EOSL date.
- Important nuance: the 6-year rule applies to general-purpose hardware. The AI/GPU-driven 2025 adjustments barely affect the mid-market.

Who is this whitepaper for?
Three roles, one question: keep running or replace — and how do I defend the decision in an audit?
CISO
CISO / Compliance
Must prove under NIS2 and BSI baseline protection that unsupported components can be operated securely — or decommission them.

Management / CFO
Faces refresh capex and CSRD duties at once. Extended useful life cuts depreciation AND Scope-3 — if it's documented defensibly.

The EOSL risk score: six dimensions, one decision
Score each system 1 (low) to 5 (high) per dimension. Dimension 2 is a hard veto: anything that cannot be securely operated under BSI OPS.1.1.3 must not keep running — regardless of cost advantage.

Extend one year instead of replacing now — what it shifts.
Simplified model from the whitepaper (not a real customer figure). It shows the levers, not a promised number: refresh is capex (large, one-off, depreciated); extending is opex (predictable, annual) — plus the avoided embodied-carbon write-off of new hardware.
