6 C-series switches and fabric rules This chapter describes the C-series Fibre Channel and FCoE switches and the fabric rules for building C-series fabrics. It describes the following topics: • C-series Fibre Channel switches, page 135 • Fibre Channel switch fabric rules, page 146 • C-series FCoE CN switches, page 151 • Fabric rules for C-series Nexus 5000 Converged Network Switches, page 153 NOTE: See "SAN fabric connectivity and switch interoperability rules" on page 167 for information about using switches from the different series in the same SAN or fabric. C-series Fibre Channel switches C-series Fibre Channel switches: • Can be core or edge switches. When configured in a core-edge topology, a core switch typically connects to other switches in the SAN; an edge switch typically connects to servers and storage. • MDS 9506, MDS 9509, and MDS 9513 Director switches can accommodate various Fibre Channel Switching Modules, IP Storage Services Modules (IPS), a Multiprotocol Services Module, a Multiservice Module, and a Storage Services Module (SSM). • The 16-port 2 Gb/s Fibre Channel Switching Module is recommended for enterprise-level host connections, storage connections, and ISL connections. • The 32-port 2 Gb/s Fibre Channel Switching Module uses 3.2:1 internal oversubscription and is recommended for low- to mid-range host connections and tape device connections. • The 12-port 4 Gb/s Fibre Channel Switching Module is recommended for high-performance 4 Gb/s enterprise-level host connections, storage connections, and ISL connections. • The 24-port 4 Gb/s Fibre Channel Switching Module uses 2:1 internal oversubscription across four 6-port port groups and is recommended for 4 Gb/s enterprise-level mid-range host and storage connections. • The 48-port 4 Gb/s Fibre Channel Switching Module uses 4:1 internal oversubscription across four 12-port port groups and is recommended for 4 Gb/s low-range host connections and tape devices connections. • The 4-port 10 Gb/s Fibre Channel Switching Module is ideal for ultrahigh-bandwidth ISL connectivity and inter-data center connection over a metropolitan optical infrastructure. • IPS modules, Multiprotocol Services Modules, and Multiservice Modules provide MDS iSCSI and FCIP functionality: • IPS-4 and IPS-8 provide 4 and 8 GbE IP ports, respectively. • The 14/2 Multiprotocol Services Module provides 14 2 Gb/s Fibre Channel ports and 2 GbE IP ports.
