Who are we?

We are digital librarians. Among us are represented the various reasons to keep data -- legal requirements, competitive requirements, uncertainty of permanence of cloud services, distaste for transmitting your data externally (e.g. government or corporate espionage), cultural and familial archivists, internet collapse preppers, and people who do it themselves so they're sure it's done right. Everyone has their reasons for curating the data they have decided to keep (either forever or For A Damn Long Time). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.

We are one. We are legion. And we're trying really hard not to forget.

Lately I received a primergy rx2530 m1, m2 and m4 (all maxed out with ram and cpus) and wonder if and which of them can be driven as energy efficient as any random diy built. I saw plenty of energy saving options on the Bios (cpu and ram related) but do not know how comparable this is with a consumer setup and which ones are important to be set. I will make my own measurements with truenas and proxmox but wonder if anyone else has those in use. I saw that the rx2540 might be the better option as it can pickup 8 x 3,5 hdd while on the rx2530s the m1 is the only one compatible with with 3,5. Also they have proprietary Hbas. Can those be switched into dumb mode where they allow the os direct access to the connected drives?

Thank you for any suggestions and sharing experiences.

Removing CPUs and RAM will also decrease its compute power. Disabling features also will likely remove some of the enterprise features like IPMI. You might end up getting the worst of both worlds - Not a ton of PCIe, few cores and RAM - but loud, and still pretty power hungry.
