Field notes
TMM is a basic BMC; remote console typically needs the premium key and a Java or HTML5 client depending on firmware level. Firmware is applied from Lenovo ThinkServer update packages, not XClarity. RAID 720ix flash modules age out and throw cache warnings. ESXi 6.7 is the safe target; replace rather than invest.
Successor: ThinkSystem SR530.

Keep it or replace it?
A ThinkServer RD350 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 ThinkServer RD350 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 ThinkServer RD350 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.
