- Eliminates single points of failure
- Efficiently replicates data changes and allows cluster nodes to quickly restore application services after a failure
- Guards against data corruption by keeping clusters from failing over to a node that has suspect data
- Implements failover clusters without shared storage or geographic limitations
- Allows you to locate cluster nodes anywhere
- Provides off-site cluster failover capabilities
- Turns Microsoft Windows Server clusters into Shared Nothing Clusters
- Stretches cluster nodes between physical locations while still using native failure detection and failover
- Ensures write-order preservation of logical application writes
- Ensures production nodes don't suffer performance degradation because of intermittent network failures or node failure
- Uses minimal CPU overhead while delivering real-world measured performance of 65-75% compression for database applications
- Maintains complete storage independence
Double-Take Availability combines continuous real-time replication and automatic failover capabilities for disaster recovery, high availability, and centralised backup on physical or virtual Windows servers. Double-Take Availability uses patented replication and failover capabilities that continuously capture byte-level changes as they occur and replicates those changes to another server either locally or over any WAN link.
Double Take Availability captures disk-writes at the host’s file system layer while all applications (including virtual machines writing to virtual disks) operate above the actual file system layer. This allows the solution to transparently and reliably protect that data by replicating it via its normal mechanisms to a target server running another copy of Double-Take Availability. On the target side, Double Take Availability simply applies the same file update commands to the duplicate files that reside on the target server – sending only real-time byte-level changes across any IP connection.
