Glossary fan-in The ratio of hosts to storage devices; the view of the SAN from the storage port's perspective. fan-out The ratio of storage devices to hosts; the view of the SAN from the host port's perspective. FastWrite A Fabric OS feature running on top of FCIP that accelerates Write operations from a host to a target device. It eliminates the latency associated with the long distance in FCIP. FC virtual initiator Fibre Channel Virtual Initiator (FC-VI). The iSCSI port looks like an F_Port to the rest of the system, with one FC-VI per iSCSI port. Brocade uses the FC proxy initiator solution. FC-VI registers to the Name Server with its symbolic port name and node name. FC-16 A 16-port SilkWorm director blade supporting 1- and 2-Gbit/sec port speeds. This port blade is compatible with only the SilkWorm 12000 (CP1) or SilkWorm 24000 (CP2) control processor blades. FC2-16 A 16-port SilkWorm director blade supporting 1- and 2-Gbit/sec port speeds. This port blade is compatible with only the SilkWorm 24000 (CP2) or SilkWorm 48000 (CP4) control processor blades. FC4-16 A 16-port SilkWorm director blade supporting 1-, 2-, and 4-Gbit/sec port speeds. This port blade is compatible with only the SilkWorm 24000 (CP2) or SilkWorm 48000 (CP4) control processor blades and does not support private devices. FC4-16IP A 16-port SilkWorm director blade enabling bridging of iSCSI hosts to Fibre Channel fabrics. It has 8 Fibre Channel optical SFP ports and 8 Gigabit Ethernet (GbE) copper RJ-45 ports. FC4-32 A 32-port SilkWorm director port blade supporting 1-, 2-, and 4-Gbit/sec port speeds. This port blade is compatible with only the SilkWorm 48000 (CP4) control processor blades and does not support private devices. FC4-48 A 48-port SilkWorm director port blade supporting 1, 2, and 4 Gbit/sec port speeds.This port blade is compatible only with the SilkWorm 48000 (CP4) control processor blades. It does not support L_Port attachments. FCIP Fibre Channel over IP. FCIP Tunneling Service A routing service that enables SANs to span longer distances than could be supported with native Fibre Channel links. FCIP is a TCP/IP-based tunneling protocol that allows the transparent interconnection of geographically distributed SAN islands through an IP-based network. The links appear as virtual E_Ports (VE_Ports) in switchShow. Fibre Channel Routing Services Fibre Channel Routing Services enables two or more fabrics to share resources (such hosts or storage devices) without merging those fabrics. See also backbone fabric, translate phantom domain, and phantom device. FCS switch In Brocade Secure Fabric OS, one or more designated switches that store and manage security parameters and configuration data for all switches in the fabric. They also act as a set of backup switches to the primary FCS switch. See also primary FCS switch. FC-SW-2 The second-generation Fibre Channel Switch Fabric standard defined by ANSI. Specifies tools and algorithms for the interconnection and initialization of Fibre Channel switches to create a multiswitch Fibre Channel fabric. Brocade Glossary 11 Publication Number: 53-1000040-03
