Figure 1 depicts an example of two applications distributed in a Metrocluster with Continuous
Access EVA P6000 for Linux 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 Continuous Access Management Software
Metrocluster with Continuous Access EVA P6000 for Linux 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.
• The SMI-S (Storage Management Interface Specification) EVA software provides the interface
for the management of P6000/EVA. Metrocluster with Continuous Access EVA P6000 for
Linux software uses OpenPegasus WBEM API to communicate with SMI-S to automatically
manage the DR Groups that are used in the application packages.
