Product Advantages
SDRS has the following advantages:
- Convenient service recovery
SDRS provides a management console. You can configure and manage server replication and perform a planned failover or failover.
- server replication
You can establish a replication relationship between the production site and the DR site.
- Replication on demand
You can replicate servers in an AZ to another AZ as required, thereby reducing the costs and complexity of maintaining another data center.
- Zero impact on applications
Applications running on servers can be replicated, and the replication will not have any impact on the applications.
- RPO target
SDRS provides continuous and synchronous replication for servers to ensure zero recovery point objective (RPO).
- Crash consistency
Storage-based, real-time data synchronization keeps crash consistency for your data across two AZs. Specifically, application data might not be consistent during a failover, but disk data is always consistent.
- Seamless DR drills
You can easily perform DR drills without affecting ongoing replication.
- Flexible failover
You can perform a planned failover for an expected service interruption to prevent data loss, or perform a failover for unexpected failures to restore services quickly.
- Efficient network switchover
SDRS simplifies program resource management during failovers, including reserving IP addresses and MAC addresses, all of which facilitates efficient network switchovers.
- Excellent performance for the price
When services are running properly, servers at the DR site are stopped and thereby will not be billed. This greatly reduces the DR TCO.
