of hard disk drives actually praise HP for the focus we place on continuous product improvement, a
process that ultimately benefits the entire HDD industry—and all of our customers.
• Product-oriented system testing: After individual components have been tested, they are integrated
into an individual EVA, and then hardware, firmware, and software teams all conduct thorough
system-level testing. Next, the EVA is integrated with a range of loosely coupled components and
devices that can interoperate on a SAN to form a computer system (host, OS, storage, and
interconnect components) and then tested with a focus on the system as a whole. This environment
is still a relatively simple one, so finding problems at this stage is easier and more cost-effective than
is still a relatively simple one, so finding problems at this stage is easier and more cost-effective than
diagnosing them in more complex environments.
• System-oriented system testing: At this stage, the EVA environment may encompass several EVAs
and host systems with different operating systems, along with SAN components and multipathing
software. Testing at this level involves multiple EVAs in complex configurations with a broad range
software. Testing at this level involves multiple EVAs in complex configurations with a broad range
of heterogeneous systems and software.
• Customer-focused testing and solution testing: Customer-focused testing is aimed at the business
objectives of a particular customer; solution tests are concerned with general solution capability.

Both types of testing occur in what is effectively a customer environment, where one or multiple
EVAs are tested in concert with related applications, middleware, and software. The EVA is
integrated with end-user applications such as Oracle Database, Microsoft Exchange, and SAP,
along with high-availability packages (clustering, Serviceguard, etc.) to form a solution that satisfies
end-user business objectives. Support materials such as white papers, best practices guides, and
end-user business objectives. Support materials such as white papers, best practices guides, and
training materials are also developed during this stage.
Where failure equals success
Testing of HP StorageWorks EVAs is continual and demanding, and its defined goal is to cause faults.
Especially in the product-oriented system testing phase, the tests are expressly designed to actively
seek out problems. As part of our efforts to test effectively, we use specialized fault injection
hardware, I/O load generators, and hardware stress tests to simulate—and exceed—the demands of
hardware, I/O load generators, and hardware stress tests to simulate—and exceed—the demands of
a customer environment. And we go far beyond customer testing, devising tests that are intense and
aggressive. As a sign in our test lab points out, “Failure = Success!”
Figure 5. Axiom of the HP EVA Test Lab
“We live to wreck things. Every failure we get in our testing is a problem
that we can fix, and an opportunity to solve a customer issue before it ever
happens. In that sense, a test failure is good news!”
