3PAR InServ E-Class/F-Class Storage Server Physical Planning Manual
6.7 Internal Cable Connections
For storage servers housed in single cabinets, internal system Fibre Channel cabling is complete
upon arrival. For multiple-cabinet configurations, the installation technician completes
connections between the controller node cabinet and the drive chassis cabinet or cabinets.
NOTE: For important exceptions to the cabling rules and guidelines described in
this section, see the InForm OS Administrator’s Guide.
NOTE: For Ethernet and Fibre Channel cables that connect the storage server to
the network and hosts, reserve approximately 7 feet (2 meters) of each cable for
internal routing within the storage server cabinet. Measure the distance between
the two cabinets and add 14 feet (4 meters) to determine the total length of cable
required.
Table 6-6 shows the typical 3PAR Fibre Channel cable lengths required for a given type of
connection:
