SIOS Product Descriptions
LifeKeeper for Linux
The LifeKeeper product includes fault detection and recovery software that provides high availability for file systems, network addresses, applications and processes running on Linux. LifeKeeper supports the configuration and switchover of a given application across multiple servers. The servers on which the application is configured are assigned priorities to determine the sequence in which the application will move from server to server in the event of multiple failures.
LifeKeeper for Linux provides switchover protection for a range of system resources. Automatic recovery is supported for the following resource types:
- Processes and Applications
- Shared Storage Devices (Including VMWare virtual hard disks)
- File Systems (ext3, ext4, vxfs, xfs and nfs) Note: btrfs is not currently supported by the LifeKeeper for Linux. For detailed information see LifeKeeper Core – Known Issues / Restrictions.
- Communication Resources (TCP/IP)
- Database Applications
DataKeeper for Linux
The SIOS DataKeeper product:
- Provides volume-based synchronous and asynchronous data replication.
- Integrates into the LifeKeeper Graphical User Interface for administration and monitoring.
- Automatically resynchronizes data between source and target servers at system recovery.
- Monitors the health of underlying system components and performs local recovery in the event of failure.
- Allows manual resource switchovers and failovers of mirrored volumes.
- Can be easily upgraded to provide high availability clustering and automatic failover and recovery using a license key to enable new functionality.
