Lenovo ThinkSystem Maintenance — vendor-independent service for SR, ST series and IBM System x
We service Lenovo ThinkSystem servers (SR, ST series) and IBM System x heritage (x3550, x3650, x3850) — vendor-independent, with OEM original parts and SLA up to 24×7×4. Also in the EOSL period. 30 to 60 percent below Lenovo Premier Support.
Which Lenovo ThinkSystem models we service
Lenovo took over IBM's x86 business in 2014. Many customers therefore have both ThinkSystem and older IBM System x in the same landscape. We service both from one source — no contract splitting needed.
Why TPM maintenance instead of Lenovo Premier Support
Lenovo Premier Support is relatively affordable — for current ThinkSystem generations, switching usually pays off only after factory warranty expires. The real opportunity lies in two scenarios: the IBM System x heritage (x3550 M3/M4/M5, x3650 M4/M5, x3850 X6) and older ThinkServer models, where Lenovo rarely offers competitive extensions.
We know both worlds — Lenovo tools (XClarity, ThinkAgile) and the IBM heritage (IMM, IPMI). We stock OEM parts for both generation lines. A single maintenance contract covers your full Lenovo + IBM x86 landscape.

EOSL status of major generations
Once the vendor ends official support, renewals become unavailable or disproportionately expensive. TPM closes exactly this gap — same hardware coverage, same SLA, significantly cheaper.
| Model family | Released | OEM support ends | TPM status |
|---|---|---|---|
| System x M3 (x3550 M3, x3650 M3) | 2010 | 2018 | Recommended |
| System x M4 (x3550 M4, x3650 M4) | 2012 | 2020 | Recommended |
