Sun Cluster 3.1 - 3.2 Hardware Administration Manual for Solaris OS

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 Sun 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 Sun 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).
