I have 3 lenovo thinksystem racks with the oldest being from 2015 and the newest v3 from late last year. I also have various other servers and storage of theirs. They, Lenovo CAN be good, BUT Lenovo dislikes customers who want to have a 7-10yr life cycle and while we strive to keep it at 5-6 years, some have to go to 7-8 which is where Lenovo gets shitty. Lenovo supports their stuff for 5 years and that’s literally not even arguable because they say it everywhere. Yes, you can keep it as long as you want but they, Lenovo will not support it. This is where I try to use HPE as they allow some of their products to get updates for decades… HPE MSA storage, Alletra/Nimble storage and HPE DL3xx servers specifically. We’re also an Aruba shop, which is now HPE so it just works best for us.
