SUNNYVALE, Calif., March 8 -- Finisar Corp., a provider of fiber optic subsystems and network test and monitoring solutions, announced yesterday it has entered into a definitive agreement to purchase the shares of InterSAN Inc., a privately held software company based in Scotts Valley, California, for approximately $9.5 million in Finisar stock. The acquired business will be operated as a part of Finisar's Network Tools Division, in Sunnyvale. The transaction is expected to close during Finisar's fourth fiscal quarter ending April 30, 2005. "While we have led the market in providing test and monitoring solutions to OEM system engineers for the Fibre Channel protocol, we believe there is a larger opportunity for providing testing and monitoring solutions for the deployed SAN market," said Kevin Cornell, senior vice president and general manager of Finisar's Network Tools Division. "IT managers are frequently unaware of their SAN performance problems or make unnecessary investments in additional hardware trying to solve those performance problems. InterSAN's Pathline software, in conjunction with our Netwisdom software and XGig hardware platform, should be a powerful combination in bringing new solutions with which to troubleshoot and monitor the performance of Fibre Channel and iSCSI SANs."
