ED-64M Director Operating Features
UPM Card
The director is configured with 4 to 16 Universal Port Module (UPM)
cards (16 to 64 ports). Each UPM card contains four duplex
small-form-factor pluggable (SFP) shortwave optic transceivers. Any
or all of the transceivers can be upgraded to longwave using an
upgrade kit available from EMC.
UPM cards use non-Open Fiber Control (OFC) Class 1 laser
transceivers that comply with Section 21 of the Code of Federal
Regulations (CFR), Subpart (J) as of the date of manufacture. Each
port can transmit or receive data at 2.125 Gb/s. G_Port functionality
depends on the type of attachment:
◆
If the G_Port is attached to a Fibre Channel device, the port
functions as a fabric port (F_Port). An F_Port is the interface on a
director that connects to a device node port (N_Port).
◆
If the G_Port is attached to another director to form an
interswitch link (ISL), the port functions as an expansion port
(E_Port). A multiswitch fabric is formed through multiple
directors and ISLs.
An ESN security feature allows the administrator to configure the
G_Port for F_Port operation only. If the data center is extended
the link outside the data center, this feature prevents the remote
user from connecting a switch and making the port an E_Port.
If the port extends the link outside the data center, this feature
prevents the remote user from connecting a switch and making
the port an E_Port.
◆
If the director G_Port is attached to the B_Port of a switch,
arbitrated loop devices attached to the switch can connect to a
multiswitch fabric. B_Ports are not assigned a Domain ID and do
not participate in fabric path selection processes.
Single-mode or multimode fiber optic cables attach to the UPM cards
through duplex LC connectors, which can be detached from the UPM
cards (through a 10-pin interface) for easy replacement.
