OUI value. However, there are some exceptions and limitations to consider before adding a switch utilizing the new OUI to an existing fabric or environment. • Fabrics with encryption products: If an HP StorageWorks encryption switch or blade using the new OUI is added to an edge fabric of a Fibre Channel routed fabric, Frame Redirection capability could be impacted across the FCR backbone, thus impacting the encryption functionality. Therefore, the FC routers in the FCR backbone fabric will need to be upgraded to a firmware version that supports the new OUI. • Interopmode 2 and 3 fabrics: In an interopmode 2 or 3 fabric with VE ports, the switches on both ends of the VE link must run a firmware version that supports the new OUI, or the VE ports may not function correctly, resulting in unpredictable behavior. DCFM compatibility Fabric OS 6.2.2e is fully compatible with DCFM 10.1.x, 10.3.x, and 10.4.x management software. DCFM is a comprehensive SAN management application that enables end-to-end management of HP B-series Data Center Fabrics. It is the next-generation product and the successor to existing B-series management products, including HP StorageWorks Fabric Manager (FM) and Enterprise Fabric Connectivity Manager (EFCM). Starting with DCFM 10.3.0, DCFM is available in three versions: • DCFM Professional-Bundled with B-series switches, it is ideally suited for small- and medium-sized businesses that need a lightweight management product to manage their smaller fabrics (one physical fabric at a time, up to 1,000 ports). • DCFM Professional Plus-Designed for medium-sized businesses or departmental storage networks, it features support for up to 4 fabrics and 2,560 ports. • DCFM Enterprise-Designed for enterprise-class customers, it showcases unparalleled performance and scalability (24 physical fabrics, up to 9,000 switch ports). This is the only version of DCFM that supports the HP StorageWorks DC SAN Backbone Director and FICON. DCFM Enterprise configures and manages DC SAN Backbone Directors, along with other B-series directors, routers, switches, and HBAs. Existing EFCM and FM customers that have active Maintenance and Support contracts are provided a seamless migration path to DCFM Enterprise. EFCM and FM compatibility With the introduction of DCFM, both EFCM and FM have been put into sustaining mode. Significant compatibility issues exist between FM and Fabric OS 6.1.1 and later, including (but not limited to) compromised functionality in the zoning dialog and performance graphs, port enabling/disabling, and FICON wizard. HP strongly recommends that customers migrate from these products to DCFM Enterprise. Fabric OS compatibility (page 11) lists the earliest versions of software supported in this release, that is, the earliest supported software versions that interoperate. HP recommends using the latest software versions to get the greatest benefit from the SAN. When using the new VF feature, HP recommends that all switches participating in a fabric with a logical switch use the latest firmware available for those switches. All switches must be operating at the minimum firmware levels noted in the Fabric OS Interoperability table. 16

DCFM compatibility
Fabric OS 6.2.2e is fully compatible with DCFM 10.1.x, 10.3.x, and 10.4.x management software.
DCFM is a comprehensive SAN management application that enables end-to-end management of
HP B-series Data Center Fabrics. It is the next-generation product and the successor to existing
B-series management products, including HP StorageWorks Fabric Manager (FM) and Enterprise
Fabric Connectivity Manager (EFCM).
Starting with DCFM 10.3.0, DCFM is available in three versions:
•
DCFM Professional
—Bundled with B-series switches, it is ideally suited for small- and
medium-sized businesses that need a lightweight management product to manage their smaller
fabrics (one physical fabric at a time, up to 1,000 ports).
•
DCFM Professional Plus
—Designed for medium-sized businesses or departmental storage
networks, it features support for up to 4 fabrics and 2,560 ports.
•
DCFM Enterprise
—Designed for enterprise-class customers, it showcases unparalleled
performance and scalability (24 physical fabrics, up to 9,000 switch ports). This is the only
version of DCFM that supports the HP StorageWorks DC SAN Backbone Director and FICON.
DCFM Enterprise configures and manages DC SAN Backbone Directors, along with other
B-series directors, routers, switches, and HBAs. Existing EFCM and FM customers that have
active Maintenance and Support contracts are provided a seamless migration path to DCFM
Enterprise.
EFCM and FM compatibility
With the introduction of DCFM, both EFCM and FM have been put into sustaining mode. Significant
compatibility issues exist between FM and Fabric OS 6.1.1 and later, including (but not limited
to) compromised functionality in the zoning dialog and performance graphs, port
enabling/disabling, and FICON wizard. HP strongly recommends that customers migrate from
these products to DCFM Enterprise.
Fabric OS compatibility

greatest benefit from the SAN.
When using the new VF feature, HP recommends that all switches participating in a fabric with a
logical switch use the latest firmware available for those switches. All switches must be operating
at the minimum firmware levels noted in the Fabric OS Interoperability table.
