document available online at https://mydocs.emc.com/VNX/ and go to VNX tasks,
then select Add VNX hardware. Next, follow the steps in the wizard.
EMC requires that an 8-bus File/Unified VNX8000 platform with greater than four Data
Movers be installed with four standard I/O modules per SP, leaving space for seven
optional I/O modules per SP. Then, in a 16-bus File/Unified VNX8000 platform with
greater than four Data Movers, EMC requires six standard I/O modules per SP, leaving
space for five optional I/O modules per SP For more information, refer to the
Adding
Storage Processor I/O modules and SFPs
document.
The following I/O modules are supported:
◆ “Four-port 8-Gb/s FC I/O module” on this page
◆ “Four-port 16-Gb/s FC I/O module” on page 51
◆ “Four-port 1-Gb/s copper iSCSI I/O module” on page 53
◆ “Two-port 10-Gb/s optical or active Twinax Fibre Channel over Ethernet (FCoE) I/O
module” on page 55
◆ “Two-port 10-Gb/s RJ-45 Base-T iSCSI/IP I/O module” on page 57
◆ “Two-port 10-Gb/s optical I/O module” on page 59
◆ “Four-port 6-Gb/s SAS I/O module” on page 61
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
(Figure 35 on page 49). 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. For more information about these SFP+ transceiver modules, see the “I/O
modules” section on page 45.
