Figure 1 depicts an example of two applications distributed in a Metrocluster with Continuous
Access EVA environment balancing the server and replication load. In this example, Site A is the
primary site or DC1 for application A, and recovery site or DC2 for application B. Site B is the
primary site or DC1 for application B, and recovery site or DC2 for application A.
HP P6000/EVA Continuous Access Management Software
Metrocluster with Continuous Access EVA requires the following two software components to be
installed in the Management Server:
• HP P6000 Command View (earlier known as HP StorageWorks HP P6000 Command View).
This software component allows you to configure and manage the storage and DR group via
a web browser interface.
• Storage Management Interface Specification (SMI-S). The SMI-S EVA software provides the
Storage Management Interface Specification (SMI-S) interface for the management of
P6000/EVAs. Metrocluster with Continuous Access EVA software uses WBEM API to
communicate with SMI-S to automatically manage the DR Groups that are used in the
application packages.
