Field notes
GPU risers and the 2000 W-class PSUs need clean power; check PSU event logs before blaming a GPU. Heavy chassis; use the proper rails and two people. Windows Server 2022 / ESXi 8.0 supported. Replace with an R760xa or XE8640 depending on whether you need SXM GPUs.
Successor: PowerEdge R750xa.

Frequently asked questions
Do you work on PowerEdge servers you did not sell?
Yes. Most of our Dell work is on servers a business already owns, in or out of warranty.
Can you update firmware without downtime?
iDRAC and some component firmware update live. BIOS, PERC and NIC firmware need a reboot, which we schedule in a maintenance window.
Can the PowerEdge R940xa 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.
