InterSystems has developed a new release of its Cache object database system that provides new development and deployment options for ISV and VAR partners who build data-intensive applications.
Topping the list of improvements in the Cache 2010 release is new database mirroring technology that the company said reduces the system's planned and unplanned downtime. The new capability provides automatic failover between any two Cache-based systems without the need for special storage and networking hardware and software.
"We think we can offer a significant level of availability," said Robert Nagle, InterSystems software development vice president, in an interview. "Early users of our mirroring capabilities project cost savings of 30 to 50 percent based on production configurations."
While most replication systems are inherently complex, Nagle emphasized that Cache Database Mirroring is simple to implement and uses logical data replication to reduce the risk of out-of-order updates and carry-forward data corruption. Mirrored database also can be housed in separate data centers.
The system allows businesses to employ redundant, less expensive servers and storage systems, according to InterSystems, and reduces the need for expensive clustering software. And it provides "warm" failover/failback capabilities, an asynchronous option for disaster recovery, and an alternative for data aggregation tasks.
