In addition, its distributed database uses primary/standby realtime synchronization for the purpose of solving data synchronization and standby of huge quantity of users and implementing cross-DC hot standby
is another expensive option that is usually outsourced to a specialist supplier.
They also cited OSE's guaranteed real-time response, which is critical for protection switching and hot standby
, and message-based interprocess communications support, which makes it easy to create scalable multiprocessor systems based on their ADM-on-a-Chip family.
It features transparent, dynamic failover to a hot standby
data mover, hardware RAID protection, nondisruptive component replacement, storage processor battery backup and advanced volume management for high availability.
By eliminating the need to deploy matching disk arrays, file servers or application servers at the secondary disaster recovery site (except for hot standby
scenarios), such systems can offer unprecedented flexibility in creating disaster recovery environments and allowing for low-cost DR planning by using low-cost JBOD or ATA-based RAID arrays at the DR center.
