System Configurations
The PowerEdge Cluster FE655W solution supports the following Fibre Channel configurations:
•Fibre Channel embedded switches connected to external SAN fabrics
•Fibre Channel embedded switches connected to up to two storage systems
•Fibre Channel
•Fibre Channel
Rules and Guidelines
When configuring your cluster, all cluster nodes must contain identical versions of the following:
•Operating systems and service packs
•Hardware, drivers, firmware or BIOS for the embedded NICs, Fibre Channel daughter cards, and any other peripheral hardware components
•Systems management software, such as Dell OpenManage™ systems management software and EMC® Navisphere® storage management software
Maximum Distance Between Cluster Nodes
The maximum distance allowed between two PowerEdge 1855/1955 server enclosures with embedded switches, or from a PowerEdge 1855/1955 server enclosure directly connected to a storage system or to an external switch, or from a switch to a storage system is 300 meters (984 feet) using multimode fiber at 2 Gbps. The maximum distance is 100 meters (328 feet) when using multimode fiber at 4 Gbps.
The total distance between a PowerEdge 1855/1955 server enclosure and a storage system, or between two PowerEdge 1855/1955 server enclosures with Fibre Channel
The maximum cable length for Fast Ethernet and copper Gigabit Ethernet is 100 meters (328 feet), and for optical Gigabit Ethernet is 550 meters (1804 feet). This distance may be extended using switches and virtual local area network (VLAN) technology.
