Business high availability cluster with dual active storage (full fault-tolerant, high secure and high reliable)
RoseStor DS provides advanced protection under its dual active storage, business continuous, full fault-tolerant architecture. Disaster recovery protection is widely realized on storage layer, channel link layer and server layer, which kills single point of failure that often happens in traditional storage architecture and ensures the business continuity of application system. It can well satisfy customer’s security protection and high availability requirements for key business data.
Both SW and HW are fully redundant, which realizes dual active storage. Besides, being compatible with different brands and specifications of HW servers and disk arrays, this product can make full use of existing resources.
When the application service, OS and server HW fails, it will auto failover related resources to standby node to keep its business continuity.
The self-developed kernel-level standby server lock can effectively prevent the error operation on disk data of standby server.
When one storage fails, the other storage will continue to provide I/O access. In this way, the data security and application operation will not be influenced at all. When the failed storage resumes, mirroring volume module will auto recover original RAID, and this recovery process will not affect the business and reduce the difficulty in operation and maintenance.
Resources like the servers, applications, storages and so on can all be managed via GUI (graphic user interface) , which realizes the centralized management and reduces the investment on operation & maintenance.
