HP StorageWorks SAN Virtualization Services Platform administrator guide (5697-8056, March 2009)

• Asynchronous remote replication
In addition to creating and managing the many objects that exist within the SVSP domain, another
purpose of the VSM user interface is to define the virtualization maps used by the DPM to perform
the virtualization of the I/O. These virtualization maps exist for each SVSP-defined virtual disk, plus
all point-in-time copies, snapshots, snapclones, and remote asynchronous mirrors.
A third function of the VSM software is to move data from one location within the domain to another
location, either within the domain, or in the case of remote mirrors, to another domain. When going
between domains, the VSM software that implements the remote mirror function can use the built-in
iSCSI interface that exists between the two domains.
Administrator tasks
The following sections describe tasks that an administrator performs either routinely, like provisioning
and daily activities such as backups, or infrequently, such as adding or removing arrays, adding
servers, and so on.
Frequently performed tasks
Figure 2 illustrates the common functions within VSM that are implemented top-down. In the figure,
four back-end logical units (BELUs) are presented by the various storage arrays to the SVSP domain.
These BELUs are concatenated together to build a pool of blocks (see Pool section). That storage pool
is used to build five virtual disks (see Volume section) that can be presented to customer servers. In
addition, two of these virtual disks are bound together into a consistency group for presentation to
Host Z.

Figure 2 The basics
Figure 3 shows a view of the VSM management user interface. While the details are provided in the
HP StorageWorks SAN Virtualization Services Platform Manager user guide, this interface is easy to
learn. Simply right-click on one of the entries (object classes) in the left navigation pane and select
