As the industry moves forward, fully
integrated high availability server platforms are an increasingly
significant requirement for customers.
As the market demands greater
purchasing efficiencies and long term cost benefits from suppliers,
many are experiencing a fundamental shift in business direction towards
the provision of fully integrated high availability server platforms
and the consequent establishment of new strategic industry
partnerships.
Whatever the final application, be it
e-mail servers, e-commerce front ends, web servers, client server
platforms, virtual private networks, CT platforms etc. - it all starts
with a computer. A typical supply chain might involve the
industrial-grade platform from Supplier A being sold to Supplier B to
integrate a systems board and then may go to Supplier C for loading of
application-specific software before being sold to the end user. For
these generally critical and costly systems, an alternative single
source of supply will present clear financial and efficiency benefits.
In this respect, I-Bus and Sun
Microsystems have recently joined forces to develop a new generation of
fully integrated, scalable high availability server platforms that can
meet price-performance targets across the OEM market. These complete
end-to-end solutions incorporate hardware and software components that
have been pre-tested, tuned for the Sun environment, and proven in
real-world environments. This offers major advantages not only in terms
of system performance, flexibility and revision control, but also in
terms of ongoing cost savings.
To this end, I-Bus and G3 Nova have
come together to provide a total solution for customers seeking fully
integrated high availability servers. The following article gives two
possible configurations, a Single-End Load Tester and an End-to-End
Load Tester.
The diagram below presents the testing
configuration of a generic Single-End Load Tester.
In the above diagram, the test
component in charge with the test synchronization, automatic SUT
locating and configuring, channels mapping and the result analysis. The
Test Agent is the test component that executes test scenarios by
generating test stimuli, record SUT responses, then reports the results
to the Test Manager. The Test Stimulus is the primitive element of the
test scenario "translated" into the SUT language. SUT Response
represents the direct or indirect effect of the Test Stimulus. For Load
Testers, multiple Test Stimuli are applied to the SUT on every channel.
In this case, SUT can be a CT Application, a CT Device or a combination
of them (e.g. IVRs, VRUs, Fax Servers, Voice Mail Systems, etc).
In the second scenario, the End-to-End
Load Tester, the diagram is as follows:
In the generic End-to-End Load Tester,
The Test = Test A + Test B, executed simultaneously. The Result =
Result A + Result B, analyzed together. For Load Testers, multiple Test
Stimuli are applied to the SUT on every channel. In this case, the SUT
could be a Switch, a Router, a Gateway or any combination of them.
As the market for high availability
platforms matures, the ability to provide a complete integration
service such as that provided by I-Bus will be an increasingly
important factor in choosing flexible solutions for the long term.
G3 NOVA Technology specializes in
mission critical, platform-independent software product development for
the Computer Telephony (CT) and Internet industries. G3 NOVA was
incorporated in 1999 as a spin-off of Genoa Technology, a world leader
in the design and development of test solutions for CT and facsimile
manufacturers.
With over 10 years of experience
managing multinational teams in the development of complex software
products (both on-site and at remote locations), G3 NOVA has a deep
understanding of software development cycles. All G3 NOVA engineers
have extensive backgrounds in software and protocol testing, insuring
the development of robust and reliable software products.
