Witness node is required in two node and stretched cluster.

for two node cluster. It may be just a regular pc if you can't afford to buy another server.
For the stretched cluster, you can use either windows or linux pc as your witness.
Is this answer helpful?

Hi, i personally suggest (after having poc and selling HCi to our customers) to avoid two nodes scenario.
This because:

the witness must be connected in a network as fast as possible because there'll be a lot of traffic amond witness and the two Sangfor nodes;
the witness node has to be an high end pc or Sangfor branded because it will keep sync a lot of metadata abotu the virtual machine state.

I suggest you to go for a three nodes connected on a fiber switch on your site. On this scenario, the witness is not required.
