Halifax Bank of Scotland (HBOS) is the UK's largest mortgage and savings provider. HBOS has a relationship with two out of every five UK households. And HBOS takes its customer relationships very seriously. In its production storage area network (SAN) computing environment, HBOS maintains over 3,000 SAN ports split across two data centers in West Yorkshire, England. of more than 300 Sun E15K servers running Solaris, 149 Brocade switches, and 250 Terabytes of Hitachi Data Systems Lightning 9900 V Series and Thunder 9500 V Series modular storage systems maintained in a split fabric configuration. One of the biggest challenges HBOS faced was the performance issues related to its SAN. When HBOS went looking for another SAN monitoring solution, and once it saw Finisar's NetWisdom SAN performance and analysis solution in action, the purchasing decision was not far behind. Finisar's NetWisdom is a real-time monitoring solution that enables SAN managers to view critical data about their networks and increase performance and reliability. HBOS is starting to baseline the performance of its systems while they are in pre-production so the company can measure the performance of the system before it is deployed into the production SAN.
