IBM Spectrum Virtualize 3-Site Orchestrator Overview

IBM Spectrum Virtualize 3-Site Orchestrator is a command-line based application that runs on a separate Linux host that configures and manages supported replication configurations on IBM Spectrum Virtualize products. IBM Spectrum Virtualize 3-Site Orchestrator coordinates replication of data for disaster recovery and high availability scenarios between systems that are on three geographically dispersed sites.

Data is replicated from the primary site or production site to two alternative sites. This feature ensures that if a disaster situation occurs at any one of the sites, the remaining two sites can establish a consistent replication operations with minimal data transfer. The remote-copy relationships are synchronous or asynchronous, depending on which site has failed.

You can use the management GUI or command-line interface (CLI) that runs on a separate Linux host that configures and manages supported replication configurations on IBM Spectrum Virtualize products. In addition to disaster recovery scenarios, IBM Spectrum Virtualize 3-Site Orchestrator supports the following use cases:

Regulatory compliance
Maintains three copies of production data.
High availability during maintenance
Ensures the availability of two copies of data during site maintenance (software update, hardware upgrade, disaster-readiness test, or other maintenance activities).
High availability during link failures
Ensures the availability of a minimum of two copies of data when a remote-copy link fails.
Site migration
For Metro Mirror configurations, two disaster recovery copies of data are maintained during site migration. In HyperSwap® configurations, you can migrate a HyperSwap system from one location to another location by using the data at the auxiliary-far site.
System load balancing
Distributes replication source between two near sites.
The system supports IBM Spectrum Virtualize 3-Site Orchestrator to configure and manage Metro Mirror configurations that span three sites. In addition, on system models that support HyperSwap configurations, you can use IBM Spectrum Virtualize 3-Site Orchestrator to extend the configuration to a third site. Only the FlashSystem 5030 or the FlashSystem 5035 model supports HyperSwap configurations. Both configurations require that you set up specific objects on each system and 3-Site Orchestrator settings.
Note: Only one instance of IBM Spectrum Virtualize 3-Site Orchestrator to manage the 3-site configuration is supported. Multiple instances can result in unexpected data consistency and inaccurate statuses of both the 3-site configuration and 3-site consistency groups.
