WD My Cloud EX4100 has measures established in the 232 x 170 x 192 mm ( length x width x height ) and a weight reaches 2.15 kg load and 3.61 kg in the case the maximum storage capacity take advantage of slots for hard drives. To give us a visual idea of ​​the size of this platform, the WD My Cloud EX4100 has very similar dimensions - in terms of length and width - to those of a compact size laptop.

If we start to analyze the design of the WD My Cloud EX4100 from the front, the first thing we will find is a screen (with a blue background) in which different system data is displayed. On the right of this screen we have two buttons , while on the left (a little further down) is the on / off button accompanied in its lower part by a slot for USB 3.0 memories . The four slots for 3.5-inch hard drives are also located on the front., which allow any hard disk to be removed simply by lifting a small cover that works with a spring system that facilitates the insertion and removal of physical storage units.

Taking a closer look at the WD My Cloud EX4100 screen , it should be noted that this screen displays the following information: system status , free storage space , drive health status , fan speed , operating system version , temperature , IP address and name of the platform , as well as other information that appears depending on the process that the platform is executing.

Already on the back of the WD My Cloud EX4100 what we find are two USB 3.0 slots , two Ethernet ports and two power inputs , as well as a small slot that allows you to restart the system if necessary.

Commissioning and initial configuration

For a user who has not had contact with this type of platform, probably one of the biggest unknowns regarding the WD My Cloud EX4100 lies in its start-up and, specifically, in the level of difficulty of its initial configuration. When it comes to physical connections, the first time this platform is configured it is only necessary to connect two cables : the power cable and the Ethernet cable that goes from the router / modem to the WD My Cloud EX4100 platform .

Once the physical connections have been made, the next thing to do is proceed to turn on the platform. To do this, you have to press the power button located on the front of the WD My Cloud EX4100 , and the system will automatically go into operation. During the first seconds it can be seen that the fans work at full power, but after that time they return to a conventional speed at the same time that the platform finishes its initial startup configuration.

With the WD My Cloud EX4100 platform up and running, the next thing to do is configure the remote access you want to assign to this system. To do this, simply enter the IP address that the platform shows on the platform screen in the computer's browser (connected to the same network as the storage system) ; Afterwards, an access password must be assigned to the default user in order to configure the system from the computer on subsequent occasions. From here, every time we want to make some configuration in our WD My Cloud EX4100 unit we will simply have to access the IP addressof the platform from the browser, entering the previously configured access data.

One method of copying files to WD My Cloud EX4100 hard drives that deserves special mention is snapshot copying from external memory. It turns out that the USB 3.0 slot that this platform has on its front is accompanied by a button. At the moment in which we insert a memory (or an external storage device pressed by USB ), when pressing this button the files of the external memory are automatically copied to the hard drives of the WD My Cloud EX4100 , without the need to perform any management from the computer.

On the other hand, the WD My Cloud EX4100 has a sleep mode that is automatically activated after a certain time without any activity on the hard drives. This sleep mode reduces power consumption and virtually eliminates fan noise; Furthermore, to restart the platform, you only need to log into one of the cloud storage tools connected to the system. This energy saving mode can be deactivated or further configured from the platform's control panel.
