Our Portfolio

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 time! “Always ON” is a prerequisite for many companies! Downtime costs money and image!

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

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.

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.

Customer Benefits ClusterLion increases the availability of your NetApp MetroCluster. Even in the event of site failures alle MetroCluser services will be properly delivered and applications remain available. ClusterLion works with only two datacentre locations. This reduces costs and complexity. A third site (Quorum) will be provided by ProLion. ClusterLion prevents data corruption in case of Split Brain syndrome. ClusterLion permanantly ensures a consistent state in the storage cluster. ClusterLion can be retrofitted to any existing storage cluster without downtime

What‘s next…

The question is not if you can afford ClusterLion! The question is if you can afford to run operation without ClusterLion? The question is not if you can afford ClusterLion!
