An individual Hitachi Content Platform (HCP) system maintains a repository of objects in one or more namespaces. To ensure data availability and protect against data corruption, namespaces can be configured (using service plans) to store multiple copies of each object. However, storing multiple copies of objects on only one system does not provide protection against the unavailability or loss of that system.
You can create a configuration in which selected tenants and namespaces are maintained on two or more HCP systems and the objects in those namespaces are managed across those systems. This cross-system management helps ensure that data is well-protected against the unavailability or catastrophic failure of a system. Depending on the number of systems and how you configure the relationships between them, data could even be protected against the concurrent unavailability or loss of more than one system.
Typically, the systems involved in cross-system data management are in separate geographic locations and are connected by a high-speed wide area network. This arrangement provides geographically distributed data protection (called geo-protection). You have multiple options for implementing geo-protection, each with its own benefits and drawbacks.
This section of the Help provides an overview of how geo-protection works and how it supports business continuity and disaster recovery.
