ClusterLion supports all common platforms. With SAP HANA systems, a shutdown of the primary
site is often necessary before a takeover to avoid data inconsistencies. ClusterLion offers perfect

datacentre.
Nothing to install on SAP hosts, no
shared storage, no 3rd data centre
MONITORING Easy, Web-GUI based configuration.
Only outgoing connection, no firewall
ports to be opened.
No user data is transmitted to the
cloud, only status metrics.

Internet due to local configuration.Architecture and functionality overview
The quorum analyzes and correlates
the status values from both sides.
SHUTDOWN If a failure is detected that requires a
takeover, the ClusterLion first shuts
down the hosts or services on the
primary side.
As soon as this is done and data
SHUTDOWN consistency has been ensured, the
takeover process begins.Architecture and functionality overview
All processes necessary for a
complete failover are automated.
TAKEOVER The HANA database is taken over to
the secondary site.
Application server central instances
are switched over.
Virtual IP addresses are switched
over.
TAKEOVER
The clients stay connected!Special integrations
Thanks to Azure API integration and Azure Load Balancer support,
ClusterLion is ideal for use on SAP systems that are operated on
native VMs in Azure.
