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.
LifeKeeper Single Server Protection Software is bundled and runs on 64-bit systems (x86_64, AMD64) and is comprised of the following components:
- LifeKeeper Single Server Protection Software
- SteelEye Management Console with LifeKeeper Single Server Protection vSphere Client Plug-in (optional software for VMware environments only)

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.
|Linux Operating System
|See the Linux Configuration Table for specific operating system information.
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 SIOS Protection Suite for Linux is deployed. Please refer to the Support Matrix for detailed versions of supported virtualization environments.
|The minimum memory requirement for a system running LifeKeeper Single Server Protection is 512 MB. This is the minimum amount required by LifeKeeper Single Server Protection supported Linux distributions. System memory should be sized for the applications that will be running on the LifeKeeper Single Server Protection protected system as well.
The LifeKeeper Single Server Protection requires the following disk space:
/opt – approx 100000-105000 (1024-byte) disk blocks (depending on kits installed)
/ – approx 110000 (1024-byte) disk blocks
LifeKeeper Single Server Protection Support Software Requirements
The following table of Supporting Software is only required in VMware VMs configured for VM and Application Monitoring.
VMware vSphere Client (for LifeKeeper Single Server Protection vSphere Client Plug-in functionality)
VMware Tools installed and running on all protected virtual machines
VMware Application HA monitoring must be enabled and set to VM and Application Monitoring for all protected virtual machines
|Approximately 175 KB in /opt (for VMware Tools
Client Platforms and Browsers
The LifeKeeper Single Server Protection web client can run on any platform that provides support for Java Runtime Environment JRE8 update 51. The currently supported configurations are Firefox (Firefox 51 or earler) and Internet Explorer on Linux, Windows Server 2008 R2, Windows Server 2012 R2, Windows Server 2016, Windows 7, Windows 8 or Windows 10 with JRE8 update 51. Other recent platforms and browsers will likely work with the SPS web client, but they have not been tested by SIOS Technology Corp. In addition, particular features of each browser also have not been tested.
IP addresses for LifeKeeper Single Server Protection components (e.g. the SteelEye Management Console and vCenter when installed in a VMware configuration) and protected Linux guests must be resolvable via DNS or the local hosts file (usually/etc/hosts or C:\windows\system32\drivers\etc\hosts). Using the local hosts file minimizes the client connection time and allows the client to connect even in the event of a Domain Name Server (DNS) failure.
See the Troubleshooting section in LifeKeeper Single Server Protection for Linux Technical Documentation for known issues, workarounds and other troubleshooting information.
