Enterprise NAS - Synology DS409

    I decided to give a brief overview of Synology DS409, which I recently acquired as a network corporate file storage.

    Technical specifications:
    HDD : SATA I, SATA II x 4
    RAID : JBOD, 0, 1, 5, 6, 5 + Spare
    Processor : 1.2 GHz
    Memory : 256 MB
    Network protocols : CIFS, AFP (3.1), FTP, NFS, Telnet / SSH
    Network interface : Gigabit Ethernet
    Management : Web interface (AJAX)
    Dimensions, weight : 230x168x184 mm, 2.23 kg
    Downloading files without using a computer: BitTorrent, FTP, HTTP, eMule, NZB
    Operating system : Linux
    Other : Print server (up to 2), Windows ADS, support for Hibernation mode, support for IP cameras (up to 5)

    Why was it decided to purchase NAS I think it’s clear. The files were on the server, where RAID was probably raised, but due to the terminal nature of the server, the danger of virus infection, and similar factors, fault tolerance was reduced, and the possibility of information collapse was significantly increased.
    Now about the Synology DS409. The NAS requirements were approximately the following:

    • RAID 0.1 support
    • User authorization through Microsoft Active Directory
    • Linux as an OS
    • The ability to connect 4 hard drives (to organize a healthy RAID array)
    • The ability to connect SAS disks
    • Built-in FTP, gigabit interface, and other small sweets

    As you can see, the device came up almost completely. The only thing is that there is no way to connect SAS hard drives, which I so desired to put there. But, fortunately (or unfortunately), due to the limited budget, this factor has ceased to be critical; therefore, 4 Western Digital WD10EADS 1000Gb were purchased.
    The interface, as you can see, is pretty nice, all the transitions, as expected, are implemented through AJAX.


    Now about what it is worth talking about.

    Management of root directories occurs through the same web face. Rights, respectively, can only be distributed to root folders.


    NAS can be turned on and off as scheduled (for example, only during business hours).
    The following applications are preinstalled on the NAS: iTunes, Web Station, Audio Station, Photo Station, Download Station, Surveillance Station (for IP video cameras).

    Reservation is carried out in the same way by regular means, both according to the schedule, and at the same time at will.

    It is possible to connect external USB drives, printers.

    And the most important thing for me: the ability to authorize users through the Microsoft Active Directory Service.

    All the principles of our corporate network are built on integration with AD, and this device allows you to appropriately distribute rights to directories (for example, right now rights are distributed across organizational units + general file storage + hidden system folders with software, etc.).


    True, even on the manufacturer’s website, built-in ADS support was announced, at the time of purchase (August 2009) it was not in the standard firmware, I had to roll fresh. But it took about 5 minutes, so there were no problems.
    Setting user rights is pretty straightforward. We select the type of users, select the users themselves, select the necessary rights (write / read / no access).


    The device has been working in constant mode for 4 months now; no failures have been noticed even once. The only problem I had was with ADS. Once the device simply stopped letting anyone in. It turned out that the NAS for some reason lost the domain. I went into the administration panel, rewrote the domain name, entered the administrator data - and it worked. All rights, fortunately, remained in place.

    The device works almost silently (for example, a nearby hanging D-Link switch makes noise 5 times louder).

    The cost of this model is ~ 17000 RUR. I got about 30,000 RUR with disks.

    In general, I believe that this NAS is quite worthy of respect and highly recommend it for use.

    PS Here you can read the official information about the device.

    PPS By the way, here I found an overview of a similar device (Synology DS209 +). You can see a more complete overview of the features of the administration panel (although the versions are different, they are very similar).
