4. High Availability in IT
High availability is a MUST in today’s IT world!
This applies across industries
Mission-critical applications must be available at all times!
Permanent IT availability and “Always ON” is a prerequisite for many companies and no longer an option.
Any downtime costs money and image

5. Cost of Downtime
The cost by industry and studies vary, but it is clear that IT downtime causes considerable damage!

6. Split-brain Syndrome
Wikipedia: Split-brain indicates data or availability inconsistencies originating from the maintenance of two separate data sets with overlap in scope, either because of servers in a network design, or a failure condition based on servers not communicating and synchronizing their data to each other.
High-availability clusters usually use a heartbeat private network connection which is used to monitor the health and status of each node in the cluster. For example the split-brain syndrome may occur when all of the private links go down simultaneously, but the cluster nodes are still running, each one believing they are the only one running.

7. The Challenge of Every Storage Cluster
Every storage vendor on the market needs a quorum, witness or tie-breaker to run automatic switchover in case of site-failure!
Expensive infrastructure investments in a 3rd data center location and highly redundant interconnects form the primary data centers to the quorum site are required!
With ClusterLion no infrastructure investment is needed, which offers the lowest possible TCO for automatic switchover.
ClusterLion is only available for NetApp MetroCluster.

ClusterLion works with only two locations. This reduces costs and complexity.
A third site (Quorum) will be provided by ProLion free of charge.
ClusterLion prevents data corruption in case of Split Brain syndrome.
ClusterLion permanantly ensures a consistent state in the storage cluster.
ClusterLion can be retrofitted at any existing storage cluster.

...if you can afford to operate without ClusterLion?
