Deploying Meridian for high availability

Meridian Enterprise can be deployed in virtualized, high availability infrastructures like VMware or Microsoft Hyper-V in a Windows Server failover cluster or similar environment. By doing so, the underlying IT architecture provides high availability for Meridian Enterprise. Other scenarios for partial high availability or switchover are also possible.

For example, using VMware vSphere Replication, a production Meridian Enterprise server running on a virtual machine can be replicated to one or more copies in real time. If the production server fails, services can be switched over to a shadow server with minimal effort and time loss.

Meridian Explorer runs on Microsoft and Oracle systems for storing, managing, and serving documents and their metadata. It can thereby claim high availability when the Microsoft SQL Server or Oracle database is run in a high availability cluster.

If a virtualized environment is not an option, certain components of Meridian Enterprise can achieve high availability with the aid of other infrastructure or 3rd party tools.

• Database – The Microsoft SQL Server or Oracle database can be deployed on a high availability cluster.
• Clients – The Meridian Enterprise PowerUser client can be deployed using remote access technology.
• Viewer – AutoVue can be deployed in a client/server configuration.
• Rendering – Multiple Meridian Enterprise Server computers can be configured as a cluster to improve rendering performance.
• Data storage – The documents stored in Meridian Enterprise can be hosted on a RAID 6 disk subsystem to provide a high level of protection against hard disk failures.
