Idle computing capacity that installed, online, but is not being used all the time is exactly what I thought the OP was talking about and calling spare. They said computing power to spare, not space or equipment. I don’t understand your argument about installing equipment, that to me isn’t what OP was talking about. 🤷‍♀️ Kinda like the spare capacity that CompuServe had from their time sharing service that they used to bring their online service to the masses at night.

Sorry you didn’t appreciate my reply. I was trying to explain my point with real examples from my experience. I don’t need your validation. I kinda regret trying to make you see both sides now. But whatever, you do you.

I don’t, but I’ll run some and try to remember to post back.

Nice writeup. As long as you can throw fast drives, fast networking and plenty of RAM at it Ceph is happy.

Ceph seems to work fine on my cluster at work. For less than $40k I replaced my whole VMware vSAN cluster and we’re saving as much again in software licensing over the next 5 years with buying support from Proxmox. Also much lighter as far as administrative tasks to keep it up to date and running well.

3x Supermicro SSG-110P-NTR10

• Intel Xeon Gold 5713
• 256 GB RAM
• 10 Intel D7-P5510 3.84TB NVME
• 2 Micron 5400 Max
• Onboard dual 10GbE
• Mellanox ConnectX4 Dual SFP28 25GbE
• 5 year NBD parts warranty

I mean yeah, but no. It is spare capacity, so it’s spare in one way.

I have hundreds of gigaflops of computing power sitting idle 80% of the time, I just don’t think the taxpayers would appreciate the power bill if I put it all to use like that. But at home I can spare a few cycles on my solar power sipping Proxmox cluster.

One would assume they mean sitting around, doing nothing. Some would rather use some electricity to support a good cause than have the computing power sit there idle.
