Infortrend EONSTOR A16E-G2130-4 User Manual

Chapter 1: Introduction 

The heart of the A16E-G2130-4 RAID controller subsystem is the iSCSI-to-

SATA controller board. The controller comes with four (4) GbE Ethernet 

host ports. The subsystem connects to the host through RJ-45 connectors, 

while the connectors are also ready to connect to one or more network 

switches, enabling access to your storage volumes in complex 

configurations such as data-sharing or network zoning.  

The docking connector at the rear of the controller board connects the 

controller module to the backplane board. A DDR RAM DIMM socket is 

strategically placed in an easily accessible location on the controller board 

for easy insertion of the DDR RAM DIMM module. 

All external interfaces that connect to external devices are located on the 

controller module rear panel shown below. The interfaces are listed below. 

 

  Host ports: Four (4) Gigabit Ethernet host ports (simulated and 

indicated as CH0 to CH3 in the diagram shown above) connect the 

EonStor subsystem to the networked iSCSI initiators through RJ-45 

connectors. 

  COM port: The controller module comes with two (2) COM ports. 

The serial ports are used for local access to the firmware embedded 

configuration utility and the connection to a UPS device. 

  LED indicators: Six (6) LED indicators illustrate the system 

statuses for system monitoring. Please see Chapter 3 for more 

information.  

  Ejection Levers: Two (2) ejection levers located on the sides of 

the controller ensure that the back-end connectors are properly 

seated in the module slot and properly mated with the backplane.   

  Management LAN Port: Another 10/100BaseT Ethernet port 

connects the subsystem to a management computer. Available
