It will run only on a single node, i.e. the node that the session requesting it is running from. If another session from another node requests the data page, it will create another data page on that node.

Suppose there are 2 servers/nodes.

For the first requestor, the request goes to 1st server, now a node-level data page will be created. 

For the second requestor, the request goes to 2nd server, again a node-level data page will be created since in the 2nd server, the node-level data page is not present there.

Again for a new requestor, the requestor will either go the 1st/2nd server, in this case, the data page will be shared.

Hope I am clear.
