Shared link

A shared link configuration, as shown in Figure 4, uses only one ISL between the

fabrics. While it is supported, this configuration is not recommended when high

availability is necessary, because it does not allow redundancy between SANs. It

may also decrease performance because the bandwidth available for storage is

shared between the two fabrics.

Zoning considerations

Customers can create a variation on the dual fabric solution that dedicates external

interface ports on the array to either server or Continuous Access input and output.

Figure 5 shows how fabric zoning is used to dedicate these ports.
