Running node for mining and RPCs?

[FraughtWithFOMO]

Hello bitcointalk,

I have bitcoin core 0.21.0 running on a PC with a single processor, 1tb SSD, and 4gb of ram.  I also have a duel-processor  server I can install VMs on but I don't have SSDs large enough to run more unpruned nodes.  I want to run an electrumx server, run asic miners (solo) and run a lightning node. 

1. Would that be safe and practical to run all those functions on one node? 
2. Should I have a separate node for each separate function?   
3. If I have multiple VMs running nodes can they share the block directory on a network drive?

Thank you in advance for your help.

As for mining, Bitcoin Core itself no longer support mining. You need to use different software.

Bitcoin Core still has getblocktemplate's RPC functional. It should still be able to be used as a node for solomining.
