Fibre-Channel Cable Connections

The Direct Backup Engine connections are the physical paths used by the

XP Disk Array to communicate with the backup devices. The XP Disk

Array and backup devices are connected via fibre-channel interface cables.

When fibre-channel interface (multimode shortwave) connections are

used, 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.

When fibre-channel interface (single-mode longwave) connections are

used, two switches are required for distances greater than 10 km (6.2

miles), and distances up to 30 km (18.6 miles) are supported.
