SUNNYVALE, CA--(Marketwire - September 17, 2007) - A world leader in high-speed communications testing and monitoring technology, Finisar Corporation (NASDAQ: FNSR) today announced that its NetWisdom® Enterprise products have successfully completed interoperability testing with a broad spectrum of IBM's System Storage products and have been confirmed as IBM System Storage Proven®. The IBM System Storage Proven program builds on IBM's already extensive interoperability efforts to develop and deliver products and solutions that work together with third-party products that represent best practice in storage.

"Finisar's NetWisdom Enterprise family provides complete visibility into Enterprise Storage Area Network (SAN) operation. It enables enterprise storage organizations to quickly get to the bottom of real and perceived SAN issues," said Paul Hansen, vice president of marketing at Finisar. "Our participation in IBM's System Storage Proven program demonstrates that Finisar and IBM are committed to providing the highest quality solution for SAN performance and availability management."

NetWisdom Enterprise is a family of SAN monitoring and analysis solutions that increase application availability and optimize performance in enterprise storage environments. NetWisdom Enterprise eliminates 'fabric blindness,' the inability to understand traffic flows, outages, and slowdowns that increasingly plague today's complex, multi-vendor data centers.

Finisar's comprehensive product suite includes NetWisdom software, Fibre Channel probes, enterprise rovers, Xgig® protocol analyzers, and high density optical traffic analysis points (TAPs). These products provide real-time and historical insight into application latency, bandwidth consumption, load balancing, and other performance metrics. NetWisdom provides early detection of link and device failures, congestion, errors, and advanced notification of other SAN problems. These issues, if undetected, can cause network downtime, application slowdown, and ultimately revenue loss for global enterprises.

The IBM System Storage Proven program recognizes the ability of independent hardware and software vendors to build high-quality storage solutions with the latest technology. IBM System Storage Proven testing enables enterprise storage operators to reduce SAN design time and deploy best practice solutions by using IBM pre-tested building blocks.

Extensive testing done through the IBM System Storage Proven program demonstrates interoperability of the NetWisdom solution with IBM System Storage SAN Volume Controller (SVC), IBM System Storage DS4000, IBM System Storage DS6000, and IBM System Storage DS8000 series products. NetWisdom Enterprise, industry's unique SAN performance and availability management solution, can now be deployed with IBM System Storage products to maximize the performance and availability of Enterprise SAN infrastructures.
