High availability within a single site

You can review the information about high availability within a single site.

Single points of failure
Single points of failure (SPOF) are points at which a system failure might occur in your data center, if the wrong configuration is set.
Ensuring against node failure
There are multiple ways to protect your system from node failure.
Database server as a critical system component
The database server is a critical system component. The entire system is unavailable if the database server crashes.
SAN or disk subsystem as a critical system component
The disk subsystem is another critical system component. Disk failures could cause outage to parts of or the entire system.

Networked file systems in Sterling Order Management System Software
If you choose this approach, consider implementing a highly available NFS to prevent an outage of the NFS server from creating an application outage. Losing the NFS server crashes all the servers of Sterling Order Management System Software.
