We have DELL servers and workstations that have been running for 5 to 6 years now. I can see the CPU utilization is reaching over 90% lately; although no new softwares were installed. We tried a fresh installations but the same issue remains.
I would like to propose hardware refreshment to my superiors, but I need justification (Since I am asking to replace over 50 systems).
Can I get help with the following (supporting documents would be great):
-Is there a mean life time for CPU, motherboard, RAMs and Hardwar in general (especially DELL systems)?
-Is there a recommended replacement guideline for systems that are running 24/7 a year?
Systems are running WIN OS.
