SPARC: Determining Campus Cluster Interconnect Technologies

This section lists the supported technologies for the private cluster interconnect and the public networks and their various distance limits. You must observe these limits when constructing a campus cluster

SPARC: Cluster Interconnect Technologies

Table 7–2 lists supported node-to-node link technologies and their limitations.

Table 7–2 SPARC: Campus Cluster Interconnect Technologies and Distance Limitations


Link Technology	Maximum Distance
100 Mbps Ethernet, unshielded twisted pair (UTP)	100 meters per segment
1000 Mbps Ethernet, UTP	100 meters per segment
1000 Mbps Ethernet, 62.5/125 micron multimode fiber (MMF)	260 meters per segment
1000 Mbps Ethernet, 50/125 micron MMF	550 meters per segment
DWDM	200 kilometers and up

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