## Determining Campus Cluster Connection Technologies

This section lists example technologies for the private cluster interconnect and for the data paths and their various distance limits. In some cases, it is possible to extend these limits. For more information, ask your Oracle representative.

### Cluster Interconnect Technologies

The following table lists example node-to-node link technologies and their limitations.

Table 7-2 Campus Cluster Interconnect Technologies and Distance Limits

Link Technology | Maximum Distance | Comments
--- | --- | ---
100 Mbps Ethernet | 100 meters per segment | Unshielded twisted pair (UTP)
1000 Mbps Ethernet | 100 meters per segment | UTP
1000 Mbps Ethernet | 260 meters per segment | 62.5/125 micron multimode fiber (MMF)
1000 Mbps Ethernet | 550 meters per segment | 50/125 micron MMF
1000 Mbps Ethernet (FC) | 10 kilometers at 1 Gbps | 9/125 micron single-mode fiber (SMF)
DWDM | 200 kilometers and up |
Other |  | Consult your Oracle representative

Always check your vendor documentation for technology-specific requirements and limitations.

### Storage Area Network Technologies

The following table lists example link technologies for the cluster data paths and the distance limits for a single interswitch link (ISL).

Table 7-3 ISL Limits

Link Technology | Maximum Distance | Comments
--- | --- | ---
FC short-wave gigabit interface converter (GBIC) | 500 meters at 1 Gbps | 50/125 micron MMF
FC long-wave GBIC | 10 kilometers at 1 Gbps | 9/125 micron SMF
FC short-wave small form-factor pluggable (SFP) | 300 meters at 2 Gbps | 62.5/125 micron MMF
FC short-wave SFP | 500 meters at 2 Gbps | 62.5/125 micron MMF
FC long-wave SFP | 10 kilometers at 2 Gbps | 9/125 micron SMF
DWDM | 200 kilometers and up |
