3.1 Available Setup Methods
This chapter explains how to set up and configure 3PAR Remote Copy. Use these instructions if
you are setting up Remote Copy for the first time. However, depending on your level of
experience, there are three methods you can choose to set up a Remote Copy configuration:
■ If this is your first experience with setting up Remote Copy, particularly for N-to-1 or
1-to N configurations, or when N-to-1 or 1-to-N and bidirectional Remote Copy
configurations are planned, you might consider using the Preparing for Setup and
Gathering Necessary Information sections that follow.
■ Users familiar with 3PAR’s Remote Copy setup can use the 3PAR Remote Copy Setup Tool
for RCIP (320-1461) or the 3PAR Remote Copy Setup Tool for RCFC (320-1472) for a 1-to-1
configuration to help configure, test and visualize the setup for Remote Copy over IP (RCIP)
and Remote Copy over Fibre Channel (RCFC), respectively. See the Document Control
System (DCS) to obtain these documents and follow the directions found in the document
that best suits your configuration.
■ Expert users might prefer to use Appendix A, Quick Setup Guide.
The final section of this chapter demonstrates how to perform an initial synchronization when
using tape rather than synchronizing a secondary volume with the primary volume over the
Remote Copy links.
3.2 Preparing for Setup
Before proceeding with Remote Copy setup, review Requirements and Restrictions on
page 2.41. The following guidelines and restrictions also apply to Remote Copy setup:
■ Synchronous mode replication is recommended for distances no greater than a
Metropolitan Area Network (MAN). A MAN is a region larger than that covered by a Local
Area Network (LAN) but smaller than that covered by a Wide Area Network (WAN).
■ The physical connections between all storage servers used with Remote Copy must be
through an IP-capable network, point to point, or an FC SAN network.
