The EMC
®
Secure Remote Support (ESRS) application architecture
consists of a secure, asynchronous messaging system designed to
support the functions of secure encrypted file transfer, monitoring of
device status, and remote execution of diagnostic activities. This
distributed solution is designed to provide a scalable, fault-tolerant,
and minimally intrusive extension to the customer’s system support
environment. Figure 1 on page 16 illustrates the major processing
components and their interconnections.
