System configuration for managing copy pairs
Device Manager supports the following four types of system configurations to manage copy pairs.
• Local management method
In this configuration, copy pairs are managed for each host by connecting a command device to
each application server via Fibre Channel.
• Configuration that uses a pair management server (central management method)
In this configuration, copy pairs are centrally managed by connecting a command device to a
computer other than application servers (pair management server) via Fibre Channel.
The central management method allows you to manage copy pairs for a host on which a Device
Manager agent cannot be installed due to the host OS.
• Configuration that uses a virtual command device server
In this configuration, a command device is connected to a computer (virtual command device
server) via Fibre Channel, and then copy pairs are managed by a computer on the LAN via the
virtual command device server.
• Configuration that uses an SVP as a virtual command device
In this configuration, copy pairs are directly managed by using an SVP as a virtual command
device instead of managed by using a storage system physical command device. You do not need
to prepare a command device for the storage system. This configuration is supported only when
both the P-VOL and S-VOL exist in HP XP7 or P9500.
There are two types of configurations: configurations in which copy pairs are defined and managed
by using a configuration definition file, and configurations in which copy pairs are defined and
managed as a device group.
