FCIP fastwrite and tape pipelining are implemented together. FC fastwrite is an FC-FC routing alternative that disables the local Ethernet ports (ge0 and ge1), making it impossible to configure FCIP fastwrite and tape pipelining and FC fastwrite on the same 400 Multi-protocol Router or FR4-18i blade. See "FC Fastwrite concepts" on page 396 for information about FC fastwrite. FC fastwrite flows may be routed to another 400 Multi-protocol Router or FR4-18i blade on the FC network. This 400 Multi-protocol Router or FR4-18i blade may have active FCIP tunnels over an IP network. FC Fabric OS 6.1.x administrator guide 393
