64 EMC VNX8000 Hardware Information Guide
I/O modules
I/O module slots
Slot 0 in each Data Mover is reserved for connections to the storage array and for optional
tape backup devices. The other available slots can contain any type of network I/O
module that is supported for the File/Unified VNX8000 platform. For more information,
refer to the
Adding an I/O module to a Data Mover document for the correct spes to add an
I/O module to a Data Mover. This procedure is available at
https://mydocs.emc.com/VNX/ and go to VNX tasks, then select Add VNX hardware. Next,
follow the steps in the wizard.
The following types of I/O modules are supported:
◆ “Four-port 8-Gb/s FC I/O module” on page 64
◆ “Four-port 1-Gb/s copper I/O module” on page 67
◆ “Two-port 10-Gb/s optical I/O module” on page 69
◆ “Two-port 10-Gb/s RJ-45 Base-T iSCSI/IP I/O module” on page 71
Note: For SP module types, go to “Storage processor I/O module types” on page 47.
Four-port 8-Gb/s FC I/O module
The four-port 8-Gb/s FC I/O module (labeled 8 GbE Fibre on the latch handle) comes with
four optical (fibre) ports, one power/fault LED, and a link/activity LED for each optical
port, as shown in Figure 51 on page 65. This I/O module can interface at speeds of 2, 4,
and 8 Gb/s.
The four-port 8-Gb/s FC I/O module uses SFP+ transceiver modules to connect to LC-type
optical fibre cables (“Lucent Connector type interface” on page 46). These SFP+
transceiver modules are input/output (I/O) devices that plug into the FC port of the FC I/O
modules. These SFP+ modules are hot swappable.

Be careful when replacing or swapping out SFP+ modules, your Data Mover will lose
access to the SP or tape drive to which it is connected.
This means that you can install and remove an SFP+ module while the VNX8000 platform
is operating.
