Implementing SAN Internetworking Solutions 4 Consolidation Solutions Another persistent problem associated with large Fibre Channel fabrics is multi-vendor incompatibility. Due to lack of common communications standards and fabric shortest path first (FSPF) protocol, switch vendors may have to support multiple (standardscompliant and proprietary) interoperability modes. In addition, protocol enhancements may force vendors to support multiple firmware versions for the same product. These issues make it difficult to connect directors or fabric switches from different original equipment manufacturers (OEMs) to build a large SAN. McDATA offers the following solutions for SAN island consolidation: • FlexPar technology - By enabling flexible partitioning (FlexPar) technology, assets can be physically consolidated while maintaining the benefits of application-based or role-based SAN islands. Refer to Flexible Partitioning Technology for additional information. • SAN routing - By installing an Eclipse 2640 SAN Router, a collection of individual Fibre Channel fabrics is connected and then functions as a single large network (routed SAN) providing any-to-any connectivity, while maintaining the autonomous nature of individual Fibre Channel fabrics. Refer to SAN Routing for additional information. Flexible Partitioning Technology Director FlexPars FlexPar technology enables the partitioning of fabric-attached devices to enable SAN island consolidation, decrease fabric congestion, or decrease the possibility of downtime. The technology enables partitioning through: • Director FlexPars - available only for the Intrepid 10000 Director. • Zone FlexPars - available for Intrepid-series directors and Sphereon-series fabric switches. • Role-based FlexPars - available for Intrepid-series directors and Sphereon-series fabric switches by mid-2005. By installing an Intrepid 10000 Director with the director FlexPar product feature enablement (PFE) key, assets can be physically consolidated while maintaining the benefits of application-based SAN islands. The feature divides the director into multiple (up to four) sub-directors, each operating with independent management and services. 4-4 McDATA Products in a SAN Environment - Planning Manual
