Redundancy
The Tempurity System allows greater reliability through the use of redundant processes. You can
download and configure multiple Tempurity Servers that collect temperatures from monitored
devices simultaneously. You can also establish several monitoring clients, each running on a
different computer, which can send alarm notifications.
The figure below shows one strategy for redundancy called “near-far”. Two Tempurity Servers and
two Tempurity Monitors have been implemented. The Tempurity Monitor at site A, shown in blue,
watches its local Tempurity Server. The site B Tempurity Server, shown in green, collects
temperatures from the monitored devices at site A; the site B Tempurity Monitor watches its local
Tempurity Server. At least one location will survive any negative event that causes large-scale
power or network failure. In this way communication alarm notifications are guaranteed as long as
power and network are available at one of the sites and both sites have a network environment that
supports e-mail transmission.
