The following sections of this chapter provide recommendations and considerations for designing business continuity and DR solutions for converged systems.
FC-WAN connectivity
Two FC-WAN configurations are supported on converged systems:
- External FC-WAN
- Internal FC-WAN (the most commonly used configuration)
Table 83. FC-WAN configurations on converged systems
External FC-WAN | FC switches with FC-WAN replication are in place. VPLEX WAN-COM replication ports connect directly to external switches, and no ISLs exist between the converged systems. |
Internal FC-WAN | The customer has one of the following: - An existing point-to-point dark fiber link, which can be terminated into the converged system FC.
- DWDM multiplexor (MUX), which can be connected with an ISL to the converged system FC switch.
Use the correct SFPs. A standard shortwave SFP has a limit of 300 meters (approximately 984 ft). If the connection is greater than 300 meters, use longwave SFPs. |
