Field notes
Out of support; firmware updates ended and IMM2 has known TLS and browser compatibility problems, so use the last UXSPI bundle and an older browser or the IMM CLI. Typical failures are PSUs and the CMOS battery. Windows Server 2019 is the last realistic Windows target; ESXi 7 is not certified. Replace with an SR250 V3.
Successor: ThinkSystem SR250.

Keep it or replace it?
A System x3250 M6 can keep doing a single job for years if it has good backups, current firmware and spare parts on the shelf. It should not be the only copy of anything, and it should not be internet-facing on an unsupported OS. We will tell you honestly whether a memory or disk upgrade buys useful time or whether the money belongs in a replacement.
Replacement planning covers the OS and licences, not only the box: a System x3250 M6 running Windows Server 2012 or an old ESXi needs a migration plan, not a lift-and-shift.

Frequently asked questions
Is Lenovo a good alternative to Dell?
Yes. ThinkSystem servers are equally reliable, often priced sharply, and XClarity management is mature. We support both and recommend whichever fits the existing fleet.
Can you still service System x servers?
Yes. System x M5 and X6 systems are legacy but parts are available and we keep them running while planning a replacement.
Can the System x3250 M6 run a current operating system?
Check the field notes above. As a rule, current models are certified for Windows Server 2022/2025, ESXi 8 and RHEL 9; legacy models usually stop at Windows Server 2019 or ESXi 7 and may need Proxmox or an older Linux to stay useful.
