Info lettura e scrittura dati su disco

Buongiorno a tutti.

Ho un dubbio che vorrei chiarire sulla gestione della lettura e scrittura su disco tra diverse macchine virtuali che risiedono sullo stesso server fisico.

Dato il server fisico ESXI00, con la macchina virtuale ERP00 installata sul Datastore00 e la macchina virtuale DB00 installata sul Datastore01, quando ERP00 legge o scrive su DB00 lo fa tramite rete o internamente?

I hope you will not mind a response in English. The write is performed through ESXi because host ESXI00 has access to both Datastore00 and Datastore01.

I think yes.

If the servers are on the same physical machine, reading and writing take place inside, not on network. Is it correct?

It takes place through the same ESXi host. If those datastores are, say, connected via iSCSI, then obviously ESXi has to talk across whatever iSCSI network you have to do I/O.

Ok, but if they are local disk (SAS), communication is internal.
