LifeKeeper Single Server Protection Product Description

LifeKeeper Single Server Protection 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 Single Server Protection is built on the proven and stable architecture of SIOS LifeKeeper. LifeKeeper Single Server Protection 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 Single Server Protection 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.

System Requirements

LifeKeeper Single Server Protection Product Requirements

LifeKeeper Single Server Protection is supported on any Linux platform that satisfies the minimum requirements included in the table below.

Description Requirement
Linux Operating System See the Linux Configuration Table for specific operating system information.
Virtual Environments The guest operating system running on the virtual machine must be one of the supported versions listed in the Linux Configuration Table. The following virtual environment is an example where LifeKeeper for Linux is deployed. Please refer to the Support Matrix for detailed versions of supported virtualization environments.

  • KVM

  • Oracle VM Server for x86

  • VMware vSphere v6.5, v6.7 and v7.0

  • Amazon EC2

  • Microsoft Azure

  • Nutanix Acropolis Hypervisor

  • Google Cloud

  • Oracle Cloud Infrastructure (See Note3)

    vSAN configuration is supported for vSphere 6.5 or later except RDM which is not supported by VMWare.

    Fiber channel SAN and shared SCSI cluster configurations are not supported with LifeKeeper for Linux running in a KVM and Oracle VM Server for x86 virtual machine.

    Note1: Some Amazon EC2 configurations have issues when the Shutdown Strategy is set to “Do not Switchover Resources”. For detailed information, see Troubleshooting > Known Issues and Restrictions.

    Note2: On SLES v12 or later running on AWS or Azure, the dynamic change of the virtual IP address by the cloud network plug-in may affect the operation of the LifeKeeper cluster. For detailed information, see LifeKeeper Core – Known Issues / Restrictions.

    Note3: Refer to Support Configuration for the supported configuration and the restrictions.
Memory The LifeKeeper for Linux minimum memory requirement is the same as the OS minimum requirement. System memory should be sized for the applications that will be running on the LifeKeeper protected system as well. Refer to Application Configuration for further information.
Memory The minimum memory requirement for a system supporting LifeKeeper is 512 MB. This is the minimum amount required by LifeKeeper supported Linux distributions. System memory should be sized for the applications that will be running on the LifeKeeper protected system as well. Refer to Application Configuration for further information.
Disk Space The LifeKeeper Package Cluster requires the following disk space:

/opt – approx 100MB (depending on kits installed)

/ – approx 110MB

Java Runtime Environment
  • OpenJDK 1.8, 10 or later

Upgrades

SSP for Linux can be upgraded to Version 9.8.0 from either LifeKeeper Version 9.6.x or Version 9.7.0. If upgrading from a version other than 9.6.x or 9.7.0, the older version will need to be uninstalled and SSP for Linux will have to be reinstalled. An alternative to uninstalling the older version would be to upgrade from the older version to 9.6.x or 9.7.0, then perform the upgrade to 9.8.0.
