Endurance Server Benefits

Description
The Endurance server uses redundant hardware and Endurance
software to ensure that your server remains operational even in the
event of a failed processor, a memory failure, an I/O failure (even
those associated with I/O controllers), a disk drive failure, or a
failed Ethernet adapter.
The Endurance server implements SplitSite technology that
enables you to locate your server across different geographic
locations. This real-time "hot site" provides a complete range of
data protection from minimal business interruptions (such as power
failure) to maximum disaster protection.
The Endurance server maintains continuous network connectivity
by detecting any network adapter or connectivity failures. If a failure
occurs, the redundant network connection continues processing all
network traffic. This ensures that Endurance server network
connections are maintained without loss of network traffic or client
connectivity.
The Endurance server can support multiple Ethernet connections
or connections to multiple networks to provide additional network
redundancy and network traffic control.
The Endurance server uses industry-standard Pentium-based
system hardware. This reduces the cost of initial ownership and
enables you to redeploy these systems if you upgrade your server.
The Endurance server can execute any Windows-compatible
application. This means that you do not have to generate support
for any special APIs or scripts to enable your application to run on
an Endurance server.
In an Endurance server, the data on mirrored devices are
automatically maintained, ensuring that data are current.
The Endurance server detects, isolates, and reports all events,
including general status, state changes, and faults. Most messages
are logged to the Windows event logs, while others are displayed
as they occur in Windows blue screens, pop-up windows, or in a
window in the Endurance Manager.
The Endurance software constantly monitors the Endurance server
for events. If an Endurance server component fails, the Endurance
server transparently uses that component's redundant counterpart.
This maintains data and user access without any loss of service to
applications.
