Abstract This white paper provides a technical overview of the Insight Recovery 1.0 product. Insight Recovery extends the capabilities of HP Insight Dynamics – VSE, providing disaster recovery (DR) protection for logical server environments. Insight Recovery extends HP’s set of solution offerings that protect customer’s applications in the event of a disaster.

definition of reasonable time varies according to the needs of the enterprise and is typically specified in a Service Level Agreement (SLA) between an IT organization that maintains the applications and the end-users who depend on those applications. An SLA contains a set of objectives or requirements regarding service availability. These are generally referred to as Service Level Objectives (SLOs). SLOs may include requirements for uptime (measured in “number of nines”, for example 99.

Overview of Insight Recovery 1.0 Concepts Insight Recovery 1.0 is a two-site solution based on the concept of a primary site and a recovery site. Insight Recovery provides a “pushbutton” automated DR failover capability that is initiated from the recovery site. Triggering a DR failover is a major decision that typically requires Executive-level approval, such as by a CIO or other “C-Level” Executive. In Insight Recovery 1.

Features Insight Recovery 1.0 provides the following key features: Insight Recovery 1.0 Feature Description Integrated with HP SIM Insight Recovery is an optional extension to Insight Dynamics – VSE. Based on a graphical user interface The configuration and management of Insight Recovery is done through a graphical interface.

• The admin activates the logical server on the primary site on a target blade or virtual machine and installs the OS and applications. Insight Recovery Configuration Steps Once the pre-configuration steps have been completed, the admin can proceed with configuring Insight Recovery at both the primary and recovery sites. The admin navigates to the Insight Recovery home screen starting from the HP SIM screen by selecting “Insight Recovery…” from the Tools drop-down menu, as illustrated below in Figure 4.
PAGE 11
Figure 5: Insight Recovery Home Screen At the Primary Site • The admin configures Insight Recovery at the primary site, and exports the configuration. • 3 The Insight Recovery configuration involves configuring Site, Storage, and Recovery Group information. A Recovery Group is a grouping of a logical server and its associated Storage Replication Group3. The admin may also specify a startup number indicating the order Recovery Groups will be started in at the Recovery Site during a failover.
PAGE 12
The configuration of Site information is illustrated below in Figure 6: Figure 6: Configuration of site information in Insight Recovery Local Site Site Name CMS Name Role of Local Site (Primary or Recovery) Description Remote Site In Figure 6, note that once the site role of the local site is specified, the site role of the remote site is deduced (for example if the local site is designated as the primary site then the remote site is automatically set to the recovery site role).

The configuration of Storage information is illustrated in Figure 7: Figure 7: Configuration of storage information in Insight Recovery Storage Type Replication Group Name Local and Remote CommandView EVA Server Names and Array WWNs Local and Remote CommandView EVA Server Credentials In Figure 7, note that in Insight Recovery 1.0, the only “Storage Type” that is supported is the HP StorageWorks EVA.
PAGE 14
The configuration of Recovery Groups is illustrated in Figure 8: Figure 8: Configuration of Recovery Groups Recovery Group Name Recovery Group Start Order Number Logical Server Name Storage Replication Group Name As shown in Figure 8, configuring a Replication Group (RG) involves specifying an RG name, the start order number of this RG (to specify that higher priority workloads should be started ahead of lower priority workloads), a logical server name, and a Storage Replication Group name.
PAGE 15
As shown in Figure 9, the admin is prompted for a location to save the configuration file. At the Recovery Site • The admin imports the Insight Recovery configuration at the recovery site. • The configuration file exported at the primary site in the previous step is transferred to the recovery site, and then is imported at the recovery site using the Import command (by invoking the Sites  Configure  Import button).
PAGE 16
After the Import process has been completed, each recovery logical server is in “Maintenance Mode”, meaning that it should be tested at the recovery site to ensure that it is working properly. Once this is done, each of the recovery logical servers must be taken out of “Maintenance Mode” in order to enable them for automatic activation by Insight Recovery in the event of a site failover.

Figure 11 – Change Local Site to Primary/Recovery buttons Change Local Site to Primary Change Local Site to Recovery (grayed-out since the site’s current role is Recovery) As illustrated in Figure 11, the Change Local Site to Primary button is only available when the local site is in the recovery site role, whereas the Change Local Site to Recovery button is grayed-out at the recovery site.

whether the disk array at the primary site and/or the inter-site links between sites were still operational following the disaster event. Another key factor in RPO is the setting of certain storage replication parameters – in particular, whether “FailSafe” and “UseNonCurrentDataOk” are enabled or disabled in the storage replication group configuration.

Figure 12: Insight Dynamics -- VSE Virtualization Manager showing Insight Recovery protected logical server Indicates that this logical server is protected by Insight Recovery In this example, there are three logical servers. Logical server “demoLS03” is protected by Insight Recovery, indicated by the tornado-with-checkmark icon. Using this interface, an admin can easily determine which logical servers are protected by Insight Recovery.

Monitoring Status Using the Insight Recovery Jobs Screen Insight Recovery has a “Jobs” graphical interface that shows the status of long-running tasks, such as the Change Local Site to Primary operation, as illustrated in Figure 13.
