SPS 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:

LifeKeeper for Linux provides Disaster Recovery protection for the following resource types:

  • Linux Multi-Site Cluster configurations in which data from a shared storage cluster is replicated to a disaster recovery site

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.

SPS Components

System Requirements

SPS Product Requirements

SPS for Linux is supported on any Linux platform that satisfies the minimum requirements included in the Linux Configuration table. Also refer to the SPS Support Matrix for supported operating systems, applications and virtualization.

Note: SPS on a Linux server will not inter-operate with SPS for Windows.

Description Requirement
Linux Operating System See the Linux Configuration table for specific operating system information.
Virtual Environments

SPS for Linux is hypervisor-independent when the guest operating system running within the virtual machine is one of the supported versions listed in the Linux Configuration Table. SIOS Protection Suite for Linux has been deployed in the following virtual environments:

  • Citrix XenServer v5 or later
  • KVM
  • Oracle Virtual Machine (OVM)
  • VMware vSphere v4, v4.1, v5, v5.1, v5.5, v6.0 and v6.5
  • Amazon EC2

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

Please refer to "LifeKeeper for Linux in VMware ESX Server Virtual Machines, Configuration Guidelines" for more detailed configuration requirements and limitations.

Fibre channel SAN and shared SCSI cluster configurations are not supported with SPS for Linux running in a KVM and Citrix XenServer virtual machine.

 

Note: Some Amazon EC2 configurations have issues when the Shutdown Strategy is set to "Do not Switchover Resources". For the detailed information, see Troubleshooting > Known issues and restrictions.

Memory

The minimum memory requirement for a system supporting SPS is 512 MB. This is the minimum amount required by SPS supported Linux distributions. System memory should be sized for the applications that will be running on the SPS protected system as well. Refer to Application Configuration for further information.

Disk Space

The SPS Package Cluster requires the following disk space: 

/opt – approx 100000-105000 (1024-byte) disk blocks (depending on kits installed)

Client Platforms and Browsers

The SPS web client can run on any platform that provides support for Java Runtime Environment JRE8 update 51. The currently supported browsers are Firefox and Internet Explorer running on Linux, Windows 2008 R2, Windows 7, Windows 8 or Windows Vista 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 have not been tested.

You should specify all the hostnames and addresses in your cluster in the client machine’s local hosts file (usually /etc/hosts or C:\windows\system32\drivers\etc\hosts). This minimizes the client connection time and allows the client to connect even in the event of a Domain Name Server (DNS) failure.

Installation and Configuration

See the SIOS Protection Suite Installation Guide for complete installation and configuration information.

Upgrades

LifeKeeper can be upgraded to Version 9.2.x from either LifeKeeper Version 9.0.x or Version 9.1.x. If upgrading from a version other than 9.0.x or 9.1.x, the older version will need to be uninstalled, and SIOS Protection Suite for Linux will have to be reinstalled. An alternative to uninstalling the older version would be to upgrade from the older version to 9.0.x or 9.1.x, then perform the upgrade to 9.2.x.

Storage and Adapter Options

For a list of the disk array storage models and adapters currently supported by SPS in shared storage configurations as well as their type of certification, see the Storage and Adapter Options topic. Details about driver versions and other configuration requirements for these arrays and adapters are listed in the Storage and Adapter Configuration topic.

Technical Notes

We strongly recommend that you read the Technical Notes section concerning configuration and operational issues related to your SPS environment.

Location of pdksh Has Changed

The location of pdksh installed by the SPS setup script in versions prior to 8.1 has changed. The pdksh was previously located at /usr/bin/ksh. It is now located at /opt/LifeKeeper/bin/ksh. Any customer written scripts that relied on the pdksh version installed by the SPS setup (/usr/bin/ksh) should be modified to reflect the new path.
