Superdomes or other large servers make up the Database Tier.
Database Tier nodes communicate with each other using HMP.
Application Tier nodes communicate with each other and to the Database Tier using TCP/UDP/IP.
Although each of the servers in the Application Tier could also have multiple adapter cards and multiple connections to switches, link and adapter card failover capabilities are not currently available for HMP.
