Introduction to McDATA Multi-Protocol Products 1 - Sphereon 4300 Fabric Switch - All switch ports are preset to a BB_Credit value of 5. By enabling the full fabric PFE key, the switch provides a port buffer pool of 144 receive BB_Credits and the per-port value is increased to 12, providing a data transmission distance of up to 24 km at 1.0625 Gbps and 12 km at 2.1250 Gbps. Refer to Full Fabric for information. - Sphereon 4400 Fabric Switch - All switch ports are preset to a BB_Credit value of 6 and the switch provides a port buffer pool of 150 receive BB_Credits. Each port can be assigned between two and 120 credits, provided the total credits allocated to all ports does not exceed 150. This provides a data transmission distance of up to 240 km at 1.0625 Gbps, 120 km at 2.1250 Gbps, and 60 km at 4.2500 Gbps. - Sphereon 4500 Fabric Switch - The first four ports (numbered 0 through 3) are preset to a BB_Credit value of 12, and the remaining ports are preset to a value of 5. Each port can be assigned between two and 120 credits, provided the total credits allocated to all ports does not exceed 150. This provides a data transmission distance of up to 240 km at 1.0625 Gbps and 120 km at 2.1250 Gbps. - Sphereon 4700 Fabric Switch - All switch ports are preset to a BB_Credit value of 12. The switch provides two port buffer pools of 235 receive BB_Credits each (470 credits total). Ports 0 through 3, 8 through 11, 16 through 19, and 24 through 27 share buffer pool zero. Ports 4 through 7, 12 through 15, 20 through 23, and 28 through 31 share buffer pool one. Each port can be assigned between two and 120 credits, provided the total credits allocated to all ports in a pool does not exceed 235. This provides a data transmission distance of up to 240 km at 1.0625 Gbps, 120 km at 2.1250 Gbps, and 60 km at 4.2500 Gbps. - Eclipse-series SAN routers - Intelligent ports that support IP network connectivity are not assigned BB_Credits. However, the ports provide approximately 96 megabytes (MB) of Transmission Control Protocol (TCP) packet buffering per transmission direction. TCP output buffering absorbs fabric data to ensure Fibre Channel BB_Credits are not exhausted. Up to eight MB of buffering can be allocated to any single iFCP or iSCSI session. 1-30 McDATA Products in a SAN Environment - Planning Manual
