Hardware Configuration

The NAS is based on the IT3107 processor from Infrant Technologies. Its 256 megabytes of DDR400 SDRAM is represented by a single SO-DIMM. You can replace this module with a larger (1-gigabyte) one to have more memory. There is also a 64-megabyte flash memory chip, a USB hub based on a VIA chip, and an auxiliary chip of the LAN controller on the PCB. The main LAN controller logic is integrated into the processor together with both SATA ports.

There are two additional cards besides the main PCB: one for the front-panel indicators, buttons and USB connector and another is a backplane for HDDs with some of the power converters. The three PCBs are connected through hard connectors which make them more robust together. A part of the HDD bays is made from plastic, probably to reduce the weight or lower the noise from vibrations.

The speed of the 60 x 60 x 25-millimeter fan is controlled automatically and the NAS is overall not very quiet because of that. If you want to use it at home, you may want to replace the default fan. This is easy: you only have to take off the side and back panels. If your new fan has a low speed, you should install a special firmware patch to avoid false-triggering the velocity sensor.

There are a few unlabeled connectors on the PCB, one of which can be accessed from the outside. This must be meant for console connection, but you won’t have to use it often considering that the NAS can be accessed via ssh.
