Yes. Oracle RAC is so called "shared disk system" (in contrast to share-nothing systems), which means that it uses disks shared by two computers. Access to the disk is synchronized by DLM (= Distributed Lock Manager), which is a part of oracle RAC. Also, on Linux, oracle delivers the OS mechanism for two nodes to communicate over the private Ethernet connection.

He is a distinguished member of this group and he used to have a good web page at http://www.oracle-dba.com, but there is not much there these days.

I dunno about the exact HW specification, but Joe Testa once wrote that he was working on RAC.
