Open Minds | Linux High Availability, Disaster Recovery and Continuous Data Protection

For a seamless recovery of your Linux servers, SteelEye Life Keeper from Open Minds guarantees to provide you with a complete disaster recovery solution ensuring that you maintain business continuity. Our high availability solutions will grant continuous data protection providing data replication as well as the monitoring of all your Linux servers to ensure failover through the Java GUI.

Replicate and monitor your Linux Servers
Replication to one or more servers takes place over a LAN or WAN continuously In addition, LifeKeeper is configured to monitor the state of all applications and services. This means that you dont need to worry if your applications and users are not functioning. LifeKeeper will automatically detect this and failover to the backup server.

Failover, Email notification and return to service
When an error occurs, you will receive an email or text informing you which server or service has been afected. After the server has been restored back into service.

Return to service

Data is automatically resynchronised from the backup to the primary server. When this is finshed, the main server can be brought back online. Return to service is automatic or manual, depending on previously set preferences.

Help with your application recovery
Open Minds can help you to plan, setup and deploy recovery for any application on your Linux servers.
As well as off-the-shelf applications like Oracle, Apache, MySQL and those listed below, we have a bespoke application recovery module which will monitor and recover any application. Your application does not need to be cluster-aware or have any special APIs for this to work.

Apache	MySQL	Samba	NFS
SAP	Oracle	VMWare ESX	DB2
Informix	Progress	PostGres	WebCT
Bespoke Applications	Sendmail	Virtual Centre	DMMP

Example solutions

1. LAN failover without shared storage (High Availability)
Data mirroring eliminates the requirement for a shared storage by mirroring application data across a LAN so that when a failover occurs, the application data is current and accessible. Replication can be done synchronous or asynchronously.

2. LAN failover with shared storage (High Availability)
Failover over a shared SCSI or Fibre environments assumes data availability is maintained by the storage architecture.

3. WAN failover (Disaster Recovery)
By combining the data mirroring capabilities of LifeKeeper with application recovery, a disaster recovery scenario that can recover a failed server to a remote site is achieved. There is no difference between the LAN and WAN solutions except the location of the servers and the underlying infrastructure.

4. 3-node combination of LAN and WAN recovery
This option replicates data to both a local and remote backup. The applications and hardware are monitored, and failover can be either local or remote. The local backup is invoked for ‘everyday’ failures or operational downtime, whereas the remote backup is invoked for site disasters.
