System information

Glossary-2 Endurance FTvirtual Server Administrator’s Guide
Disabled. A state indicating that a Endurance
component is configured as, or has been, manually
disabled. In this state, a component is not operating
as part of the Endurance Configuration. For
specific information on this state as it applies to
particular components, refer to the Endurance
FTvirtual Server Administrator’s Guide.
enable. Enables a previously disabled or failed
device for use in the Endurance Configuration.
Components are enabled by invoking of a
Endurance Manager option or an MTCCONS
command.
Endurance Configuration. A fault tolerant,
disaster tolerant virtual server that consists of two
redundantly configured systems (the CoServers)
that appear to the operator and the FTvirtual Server
operating system as one server. Running
synchronously on the two CoServers is the
FTvirtual Server, similar to a virtual operating
system, in which you perform most of your
interaction with the Endurance Configuration. The
Endurance Configuration is capable of running any
off-the-shelf Windows applications and utilities
with no modifications required.
Endurance Device Redirector. A utility you
use to define the redirected devices accessible to
the FTvirtual Server environment. Using a
graphical user interface, you define the redirected
devices and their mapping to physical devices
located on the CoServers.
Endurance Manager. A server management
application for the Endurance Configuration with a
Windows-based graphical user interface.
Endurance sector. A management sector on
all redirected disks, both mirrored and non-
mirrored, that is used to support soft SCSI ID
requirements. The Endurance sector is located on
the administrative portion of the disks (track 1); it
is not part of the data portion of the disks.
Endurance FTvirtual Server. A fault
tolerant, disaster tolerant virtual server that
consists of two Intel-based servers that appear to
the operator as one system. The FTvirtual Server is
capable of running any off-the-shelf Windows
applications and utilities with no modification
required.
Failed. A state indicating that a
Endurance
component is unusable. For specific information
on this state as it applies to particular components,
refer to the Endurance FTvirtual Server
Administrator’s Guide.
failout. A process that automatically
deconfigures a failed component and continues
processing with its redundant counterpart. This
process helps ensure no loss of service. However,
if a non-redundant device is failed out of a
Endurance Configuration, it has no counterpart to
provide continuous device access.
failover. A process that automatically
deconfigures a failed redirected Ethernet adapter.
failure. An observable malfunction of a
Endurance component.
fault management. The process of detecting a
failure, diagnosing it, and continuing to process
transactions, using either a failout or failover
process. In addition, this may include repairing one
or more component(s) and returning them to
service in the active Endurance Configuration.
