About LifeKeeper Single Server Protection for Linux
LifeKeeper Single Server Protection (SSP) allows for application monitoring in a single node configuration (i.e., no cluster requirements or restraints). Single node environments may be physical or virtual (vSphere, KVM, Amazon EC2). LifeKeeper SSP is built on the proven and stable architecture of SIOS LifeKeeper. LifeKeeper SSP provides superior application monitoring and can perform recovery of failed applications and system infrastructure items (e.g., NFS share, IP address, File System). If an application cannot be recovered for some reason, LifeKeeper SSP will initiate a restart of the node via a system reboot or via a VMware HA restart for VMware virtual machines configured for VM and Application Monitoring.
- Communication Paths
- Shared Storage (requirements, configuration, …)
- Extending / Unextending resource hierarchies
- Storage Kits (DR, DMMP, HDLM, LVM, MD, PPATH and NEC SPS)
- Resource/Machine failovers (by default with LifeKeeper SSP these result in a node restart)
- Resource switchovers
- Switchable IP Addresses (with LifeKeeper SSP Switchable IP addresses are required for some protected applications but since there is only a single node no switching actually takes place)
For more information on the SIOS LifeKeeper product, on which LifeKeeper SSP is built, please see the SIOS Protection Suite for Linux documentation for the common release number. This documentation will provide detailed information on resource hierarchy creation, resource types, states and relationships, Graphical User Interface (GUI), as well as common and advanced tasks.
