6 SAN CONFIGURATION

6.1 MANAGING FICON FABRICS

Cascaded configuration

(known as a high integrity fabric)

Figure 7: Supported FICON Topologies

SINGLE DIRECTOR REQUIREMENTS

No licenses are required unless two-byte addressing is used. Most customers are not cascading and

therefore only use single-byte addressing

Even though not required, Insistent Domain ID (IDID) should be set

• IDID guarantees that a switch operates only with its pre-assigned domain ID

CASCADED DIRECTOR REQUIREMENTS FOR M-SERIES

Requires a SANtegrity license for 2-byte addressing

Enable Enterprise Fabric Mode in EFCM which will enable:

• Fabric binding (mandatory)

• Insistent Domain ID (IDID) (mandatory)

• Switch binding (optional)

All fabric parameters must be the same
