Chapter 1: About SteelEye Protection Suite for
Windows
SteelEye Protection Suite (SPS) for Windows integrates high availability clustering and data
replication functionality to protect mission-critical data and applications. SPS also integrates with
SIOS' Application Recovery Kits, which provide application-aware agents for SQL Server, Oracle,
Exchange and more enabling you to make more informed recovery decisions.
SPS for Windows Integrated Components
LifeKeeper for Windows provides a fault resilient software solution to provide high availability for
data, applications, and communications resources. LifeKeeper does not require any customized,
fault-tolerant hardware. You simply group two or more systems and enter site-specific configuration
data. Then, LifeKeeper automatically provides fault detection and recovery.
In case of a failure, LifeKeeper migrates protected resources from the failed system to the backup
system. Users experience a brief interruption during the actual switchover, but LifeKeeper
automatically restores operations on the backup system when it completes the failover recovery.
SteelEye DataKeeper is a highly optimized host-based replication solution which ensures your data
is replicated as quickly and as efficiently as possible from your source server across the network to
one or more target servers.
Optional Microsoft SQL Server Recovery Kit provides granular visibility into SQL Server so you
can ensure your systems are properly responding – not just running.
Protected Resources
The SPS family of products includes software that allows you to provide failover protection for a
range of system resources. The figure below demonstrates SPS's flexibility and identifies the
resource types you can specify for automatic recovery:
• Volume. With LifeKeeper’s volume resource type, you can protect data and applications on
shared SCSI peripherals or replicated volumes by creating a resource in the SPS hierarchy for
the disk volume containing those resources.
• File share. SPS's LAN Manager Recovery Kit lets you protect a specific folder or directory on
a shared drive.
• Computer alias name. SPS's LAN Manager Recovery Kit enables automatic failover of the
computer alias name for applications that communicate to the server via NetBEUI.
• Communications resources.
