Implementing SAN Internetworking Solutions 4 For attached fabrics in which participating element's Interop Mode is set to McDATA Fabric 1.0, Domain_IDs of 30 and 31 are recognized by SAN management applications and all attached devices. For attached fabrics in which participating element's Interop Mode is set to Open Fabric 1.0, Domain_IDs of 30 and 31 are recognized by SAN management applications. Domain_IDs of 7E and 7F are recognized by all attached devices. As shown in Figure 4-5 from a logical connectivity perspective, fabric 1 appears as follows: • One Fibre Channel switch (Domain_ID 6) with direct-attached devices D1 and D2. • One edge switch (Domain_ID 1) that represents an R_Port. • One virtual switch (Domain_ID 30) that represents a routing domain with devices D3, D4, D5, and D6 logically attached. These devices are physically connected to Fabric 2. • One virtual switch (Domain_ID 31) that represents a routing domain with device D7 logically attached. This device is physically connected to the router. As shown in Figure 4-5 from a logical connectivity perspective, fabric 2 appears as follows: • One Fibre Channel director (Domain_ID 7) with direct-attached devices D3 and D4. • One Fibre Channel switch (Domain_ID 8) with direct-attached devices D5 and D6. • One edge switch (Domain_ID 2) that represents an R_Port. • One virtual switch (Domain_ID 30) that represents a routing domain with devices D1 and D2 logically attached. These devices are physically connected to Fabric 1. • One virtual switch (Domain_ID 31) that represents a routing domain with device D7 logically attached. This device is physically connected to the router. Routing domains represent devices from remote fabrics and are a key part of SAN routing. The routing domain with Domain_ID 30 enables routing between multiple fabrics (mSAN routing). The routing domain with Domain_ID 31 enables routing between multiple mSANs (iSAN routing). Refer to mSAN Routing or iSAN Routing for additional information. 4-14 McDATA Products in a SAN Environment - Planning Manual
