Remote copy connections

Remote copy connections are the physical paths that primary arrays use to communicate with
secondary arrays. Remote copy connections enable communications between primary and secondary
arrays. Primary and secondary arrays are connected through Fibre Channel interface cables. You
must establish paths from the primary array to the secondary array, and also from the secondary
array to the primary array. You can establish up to eight paths in each direction.

When using Fibre Channel interface (optical multimode shortwave) connections, two switches are
required for distances greater than 0.5 km (1,640 feet), and distances up to 1.5 km (4,920 feet,
0.93 miles) are supported. If the distance between primary and secondary sites is greater than
1.5 km, optical single-mode longwave interface connections are required. When using Fibre
Channel interface (single-mode longwave) connections, two switches are required for distances
greater than 10 km (6.2 miles), and distances up to 30 km (18.6 miles) are supported.
