2.5 Support for Multiple InServ Connections
The current version of 3PAR VSS Provider for Microsoft Windows supports multiple InServ
connections to the same host server where 3PAR VSS Provider for Microsoft is installed. This
allows VSS hardware snapshots to be managed from a host that is connected to multiple InServ
Storage Servers via HBA or iSCSI.
Consider the scenario where Exchange 2007 CCR is deployed in an organization with 3PAR
Recovery Manager for Exchange. The Recovery Manager for Exchange backup server will have
connections to two InServ Storage Servers where the Active Exchange Server is connected to
the first InServ Storage Server and the Passive Exchange Server is connected to the second. In
order for the Recovery Manager for Exchange backup server to support this type of CCR
configuration, the 3PAR VSS Provider on the backup server needs to have access to both InServ
Storage Servers to manage the snapshots accordingly.
Support for multiple InServ Storage Servers can be accommodated by registering the
additional InServ Storage Servers using the ProvCfg.exe utility available under the VSS
Provider installation folder. Please see Using the Command Line Interface to Set Up or Modify
an InServ Connection on page 3.18 for more information.
NOTE: By default, the 3PAR VSS Provider for Microsoft Windows installation
provides support for a single InServ Storage Server registration. Additional InServ
Storage Servers need to be set up and registered using the ProvCfg.exe utility.
