Planning Volume 2, Control Workstation and Software Environment

Benefits of a high availability control workstation

HACWS is a major component of the effort to reduce the possibility of single point of failure opportunities in the SP. There are already redundant power supplies and replaceable nodes. However, there are also many elements of hardware and software that could fail on a control workstation. With a high availability control workstation, your SP system will have the added security of a backup control workstation. Also, HACWS allows your control workstation to be powered down for maintenance or updating without affecting the entire SP system.
