Fiber-Optic Cable Information
Fiber-Optic Cable Information
Single-mode, fiber-optic cables provided by HP for ServerNet cluster installations
adhere to the IEEE 802.3z (Gigabit Ethernet) standard. The cables are terminated by
duplex subscriber connectors (SC), as shown in Figure 2-1.
Note the following considerations:
•
Single-mode, fiber-optic cables are required for connecting nodes and cluster
switches in a ServerNet cluster.
•
Multimode fiber-optic cables, FOX ring fiber-optic cables, and ATM cables are not
supported for use in a ServerNet cluster.
•
If the fiber-optic cables you use are not provided by HP, the cables must meet the
specifications in Table 2-5.
Table 2-4. Cable Length Requirements for Multilane Links
Cable Length Minimum Requirements
Up to 80 m All nodes in the cluster must meet the requirements for the split-star
topology. See Table 2-8
on page 2-23.
Up to 1 km All nodes in the cluster must be running G06.11 or a later version of the
operating system.
Up to 5 km All of the following:
•
All nodes in the cluster must be running G06.16 or a later version of
the operating system.
•
All nodes in the cluster must be S76000 or S86000.
•
All processors in all nodes must have the NSR-X or NSR-Y processor
type.
*
* You can use the OSM Service Connection or TSM Service Application to check the processor type. (TSM
displays Processor Name attribute, OSM displays Processor Type attribute.)
