Glossary
Product Manager application
Application that implements the management user interface for a specified director. When a
product instance is opened from the HAFM application’s Products View, the director Product
Manager application is invoked.
product name
User-configurable identifier assigned to a managed product. Typically, this name is stored on
the product itself. For the Director 2/64, the product name can also be accessed by an SNMP
manager as the system name.
prohibited port connection
In S/390 operating mode, an attribute that removes dynamic connectivity capability.
R_A_TOV
See resource allocation time-out value.
redundancy
Performance characteristic of a system or product whose integral components are backed up
by identical components to which operations will automatically failover in the event of a
component failure. Redundancy is a vital characteristic of virtually all high-availability (24
hours per day, seven days per week) computer systems and networks.
remote access link
Connection to a device or program on a computer network via a (geographically) remote
workstation.
remote notification
A process by which a system is able to inform remote users and/or workstations of certain
classes of events that occur on the system. E-mail notification and the configuration of SNMP
trap recipients are two examples of remote notification programs that can be implemented on
director-class switches.
remote user workstation
Workstation, such as a PC, using the HAFM and Product Manager applications that can access
the HAFM server over a LAN connection.
resource allocation time-out value (R_A_TOV)
User-specified value for time out operations that depend on the maximum possible time that a
frame could be delayed in a fabric and still be delivered.
