Hyper Messaging Protocol (HMP)
Enterprise (Database)
The HMP enterprise configuration illustrated in Figure
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/IP.
The HMP enterprise configuration is a scalable solution. If higher performance is required, or if eliminating single points of failure is necessary, scaling up to the HMP enterprise configuration with multiple connections between nodes is easily accomplished (see Figure
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.
