BladeCluster Solution Manual

BladeCluster Connections for the Long-Haul Multi-Zone Topology (3 Zones)
To participate in a BladeCluster/Multizone Solution using one of the long-distance options—25
kilometers (km), 50 km, or 65 km—both ServerNet switches in a BladeSystem anchor node must
have port 13 (labeled VA) available in slots 5 and 7. For an illustration of this ServerNet switch
port and faceplate label, see “ServerNet Switch for BladeCluster” (page 18). Only two ServerNet
links are used between the anchor nodes in a three zone long-haul configuration.
This table shows the mapping of interzone connections in the 3 zone long-haul configuration. At
each zone, the connection VA.1/2 (connector VA fibers 1 and 2) connects to the next highest
zone number. The connection VA.3/4 (connector VA fibers 3 and 4) connects to the previous zone
number. All connections are from/to the anchor nodes.

You then use MTP-4LC cables for connections between the ServerNet switch (via VA) and DWDM.
A single MTP connector at one end connects from the VA. Four LC connectors at the other end
(labeled 1 through 4) connect to the DWDM. A customer-supplied SMF cable connects the DWDMs
to provide the interzone connections. The SMF cable can usually be obtained from a Telco provider.
