Finisar's Medusa Labs Introduces New Test Tools Suite for Developers of Storage Area Network (SAN) and Network Attached Storage (NAS) Products and Components

SUNNYVALE, CA, Jul. 21, 2004 (MARKET WIRE via COMTEX) -- Finisar Corporation (NASDAQ: FNSR), a provider of network solutions, announced today that its Medusa Labs group has introduced a new Test Tools Suite for developers of Storage Area Network (SAN) and Network Attached Storage (NAS) products and components.

With over 10+ years' experience in Storage Networking testing and validation, and the recipient of the 2004 Market Leadership Award for Fibre Channel Test from Firm Frost and Sullivan, Finisar has taken its wealth of knowledge and experience in the test and validation arena and put it directly into this new test suite. Finisar's Medusa Labs Test Tool Suite is a series of benchmark speed, data integrity and stress test tools that allow test and validation engineers to better develop quality products in a shorter time frame, for faster time to market. The suite was designed specifically for engineers that work with DVT, validation, bring-up, design validation and Quality Assurance.

Finisar's Medusa Labs realized early on that there were no current industry software test tools that met the stringent testing requirements of its SAN and NAS customers. Most of the industry is using shareware benchmarks or ineffective I/O generating tools that are not capable of identifying the vast majority of bugs on most products. Finisar's Medusa Labs Test Tool Suite was specifically designed to find elusive data corruptions, I/O timeouts, I/O loss, and system lockup scenarios. The tools are very rich in debug and logging information to allow for rapid analysis of any found issues. They are designed to stress hardware and signal integrity and are also portable to all of the major operating systems so that familiarity on one platform leads to familiarity on all others.

"For the validation of our new Alacritech STA2000 multi-port Gigabit TOE ASIC, we searched for an outside test partner with the advanced I/O tools and technical expertise to assist us in ensuring we offered best-in-class technology to our customers," said Richard Blackborow, vice president, Engineering, Alacritech Inc. "We found the ability of Medusa Labs' Test Tool Suite to conduct stringent, real-world stress-tests invaluable in enabling us to deliver a TOE ASIC with the quality required by today's mission-critical storage networks."

The Medusa Test Tools Suite consists of 3 components -- I/O Tools, Test Automation and Utilities that run on a host system. At the simplest level, the test tools operate in an initiator-target fashion. The host system acts as an initiator and the target can be any storage device internal or external to the host system. The host system becomes a precision traffic generator using real-world application data. The tools are command-line based, so they are ideal for setting up scripted test runs. In addition, the Test Tools suite uses Finisar analyzers, because a substantial number of defects or deficiencies are overlooked in product development due to anomalies that are not readily visible at the application level. An analyzer is essential to detecting underlying items of interest, such as I/O fragmentation and recoverable errors, and verifying performance numbers. A powerful feature of the test tools is the ability to send an I/O with a special value for analyzer triggering. Fault conditions, which would be difficult, if not impossible, to debug and to find the root-cause from the application level can easily be captured in a trace and analyzed in detail.

"The Test Tool Suite was created because builders of SAN and NAS products require potent tests to maximize their products' performance and integrity, and to minimize their time to market," said Dr. Brian Staff, VP of Marketing, Finisar Network Tools. "Medusa Labs Test Tool Suite stresses specific areas of enterprise systems, provide superior debug and analysis capabilities, and can be ported effortlessly into multiple operating systems for ultimate user flexibility."
