• DC SAN Backbone Director and DC04 SAN Director support the 16, 32, and 48-port 8 Gb/s Fibre Channel blades, 10 Gb/s 10/6 FC ISL Blade, MP Router Blade, encryption blade, and the DC Dir Switch MP Extension Blade. • SAN Director 4/256 supports the 16, 32, and 48-port 4 Gb/s Fibre Channel blades, 16, 32, and 48-port 8 Gb/s Fibre Channel blades, 10 Gb/s 10/6 FC ISL Blade, the MP Router Blade, and iSCSI Director Blade. The B-series switches offer: • High availability • Scalability • Cost efficiency Model numbering The B-series Fibre Channel switches typically use the numbering scheme x/y: • x-The highest speed at which the switch ports can operate, measured in Gb/s • y-The number of switch ports For example, the HP StorageWorks SAN Switch 4/16 is a 4 Gb/s switch with 16 ports. The 8 Gb/s, 4 Gb/s, and 2 Gb/s switch ports autonegotiate the signaling speed. For example, when you connect a 4 Gb/s or 2 Gb/s port directly to a 1 Gb/s port, both ports run at 1 Gb/s in each direction. If the ports are not directly connected, the fabric switch that connects the ports determines the signaling speed. Model naming The B-series Fibre Channel switches are typically called HP StorageWorks SAN, SAN Backbone, Core, or Director switches. SAN Backbone, Core, and Director switches are core (enterprise-class) switches. SAN switches are edge (entry-level or mid-range) switches. The suffix -EL, V, or N identifies entry-level switches. The B-series embedded switches for HP c-Class BladeSystem servers are called the Brocade 8Gb SAN Switch for HP BladeSystem c-Class and the Brocade 4Gb SAN Switch for HP c-Class BladeSystem. The embedded switch for HP p-Class BladeSystem servers is called the Brocade 4Gb SAN Switch for HP p-Class BladeSystem. The B-series Fibre Channel routers are called the HP StorageWorks 400 Multi-protocol Router (400 MP Router), Multi-protocol Router Blade (MP Router Blade), and Multi-protocol Router (MP Router). The 8 Gb SAN extension products are called the HP StorageWorks 1606 Extension SAN Switch and HP StorageWorks DC SAN Director Multi-protocol Extension Blade. Switch models Table 18 and Table 19 describe the B-series Fibre Channel switches and routers supported by HP (8 Gb/s and 4 Gb/s B-series Fibre Channel switches). Table 20, Table 21, and Table 22 describe the HP and Compaq legacy Fibre Channel switches and routers. HP supports all B-series Fibre Channel switches in a fabric if you: • Use the firmware versions listed. All like switch models must use the same version when configured in a single-fabric or multi-fabric SAN (see Table 18 through Table 22). When updating switch firmware, you can use two successive switch firmware versions temporarily in a single-fabric and multi-fabric SAN. • Follow the fabric rules.
