2.14 Requirements and Restrictions
Remote Copy requires the use of a minimum of two InServ Storage Servers.
■ For Remote Copy over IP (RCIP), each storage server in the Remote Copy configuration must
have two nodes with 3PAR-supported GigE PCI adapters (a maximum of one adapter per
node and two adapters per system). Two adapters are required for each storage server in
order to support redundant TCP/IPlinks between systems. This limitation does not apply to
1-to-N Remote Copy. For 1-to-N Remote Copy, the primary storage server can have four
RCIP interfaces; two to one secondary system and two to the other secondary system.
■ For Remote Copy over Fibre Channel (RCFC), each storage server should have a pair of Host
Bus Adapters (HBAs) installed. The HBA pair is required for load sharing and fault
tolerance. These adapters must be reserved for exclusive use by Remote Copy. The HBAs in
each storage server connect those systems through FC SAN using Fibre Channel cable
connections (see Figure 2-18 ).

■ For RCIP configurations, the management interface cannot reside on the same network as
the RCIP network.
■ The maximum delay times are as follows:
◆ RCIP - 150 seconds
◆ RCFC - 1.5 milliseconds
◆ RCFC over IP - 60 milliseconds
