|Case Study : HP 9000 High Availability|
|Backup and SAN|
|HP 9000 High
The new infrastructure was to replace two Unisys 6000 Servers running various business applications developed using a Progress database, these were approaching the end of their 3 year maintenance contracts, Preferred were asked to investigate replacing these legacy systems with a modern, highly available platform to support the company's current and future infrastructure requirements.
A number of key requirements were identified, including:
The solution comprised two rp54X0's located at the primary & secondary site, both sites connected by dual fibre link. Each Server was connected to a fibre channel disk array via HP SAN Switches. These arrays were mirrored across primary & secondary sites, database synchronization and replication were also provided via HP-UX. The "hot standby" server had redundant links to the primary server which could be activated in the event of a primary system failure. By its very nature the ServiceGuard cluster guaranteed business continuity in the event of a disaster at either site. Both planned and unplanned downtime could now be minimised, ensuring that business-critical applications were highly available to the business.
