Thank you to everyone who went with me on this journey. For me it was extremely fruitful. I was thinking a vCPU was a thread and therefore one would need lots of cores and threads to make a Proxmox server. I can not see that is not the case. Based on all you good folks have tough me, I assu

Be very careful with ESX.  I know someone who bought a random server and ESX7 was not supported.  It used to run on anything, now, not so much.  Check the support matrix before you buy. Regards, George Toft On 7/20/2023 1:12 PM, greg zegan via PLUG-discuss wrote: Hello,   I appreciate this t

That's right, a vCPU is a shared resource. Lets say that you had a machine with 4 cores on it. To the operating system, other than some nuances with the cache, PCI connections, etc., each core is effectively its own CPU, and therefore we'll say the machine has a total of 4 CPUs. Now, just becua

Hello,  I appreciate this topic.  I have been wondering for a while now if there is an affordable home server out there for EXSi and such.  Is there any way for someone to come up with a few choices for people like me?  Is there a low end, mid range, and high end home server for someone to list
