Anyway, I have decided to buy used Dell rack server (PowerEdge R810) with 256 GB RAM mainly because of the amount of RAM but also because of all Dell servers older than 9 Generation support IPMI which is very useful. The server can be remotely managed (power on, power off, etc.) over IPMI and it also supports SOL which stands for Serial-over-LAN for server consoles. IPMI SOL is an inexpensive alternative to the iDRAC enterprise virtual console.
You can read more about IPMI on links below
- IPMI SOL – Inexpensive Remote Console
- Fun with ESXi, IPMI and Dell BMC/iDRAC – Remote Power Cycle, Console and more
"Aha, IPMI SOL will not help me too much with remote access to ESXi DCUI console."
Update: I have just found and bought very cheap iDRAC Enterprise Remote Access Card on Ebay, which supports remote virtual console and media. So, it is hardware workaround to my software problem :-)
