everRun Enterprise System Description

everRun Enterprise software allows two computers to work as a single, highly-available or fault-tolerant system. Each computer is called a physical machine.

Both physical machines (PMs):

• Run the same host operating system (CentOS)
• Contain the same data, memory and storage (synchronized via direct Ethernet links between the two PMs)
• Support virtual machines running supported guest operating systems

The PMs must:

• Have compatible CPUs
• Conform to hardware requirements for everRun Enterprise systems. See Physical Machine System Requirements and System Requirements Overview for more information.

The data and memory contents of the two PMs are synchronized via direct Ethernet links. Other Ethernet connections to a network support virtual machine and management operations.
