Port Requirements

Plan for sufficient shortwave laser ports and longwave laser ports to meet the
needs of the SAN configuration. The number of ports required is equal to the
number of device connections (including redundant connections), plus the number
of interswitch links (ISLs) between fabric elements, plus the total number of spare
port connections.
The number of Fibre Channel ports and port operation for directors and switches
are described as follows:

116
Port requirements (number and type of ports).
Small form factor pluggable (SFP) optical transceivers.
Extended-distance ports.
High-availability considerations.
Cabling and connectors.
Routing fiber-optic cables.
WARNING: Director and switch non-open fiber control (non-OFC) laser
transceivers are designed and certified for use only with fiber-optic cables and
connectors with characteristics specified by HP. Use of other connectors or
optical fiber can result in emission of laser power levels capable of producing
injury to the eye if viewed directly. Use of non-specified connectors or optical
fiber can violate the Class 1 laser classification.
Director 2/64 — The director is configured from a minimum of 8 universal
port module (UPM) cards (32 ports total), to a maximum of 16 UPM cards (64
ports total).
UPM cards provide four 2.125 Gbps port connections, and can be configured
with shortwave transceivers, longwave transceivers, and extended longwave
transceivers, or a combination of all three.
