Asustor AS-204RS overview

  • 1Description

The AS-204RS 4-Bay SMB NAS Server with 1U/2U Rail Kit from Asustor is a 4-bay rackmount NAS that can be mounted on 1U and 2U rackmount systems. It has been designed with AES 256-bit encryption for secure centralized data storage in small to medium sized businesses that will help to store, protect, and share content. Enterprise features and stability are built into the hardware design, making it a well-suited choice for growing small businesses with limited space or a limited budget. This unit has four drive bays, each of which natively supports 3.5" and 2.5" SATA III 6 Gb/s and SATA II 3 Gb/s hard drives and SSDs.

The AS-204RS is powered by a 1.2 GHz Intel Atom Z2520 Dual-Core processor, which will allow you to run multiple functions simultaneously. The built-in 1GB of DDR3 RAM will allow quick access to frequently-used files and programs. Network connectivity is achieved via the 2 x Gigabit Ethernet ports and external peripherals may be connected using the 4 x USB 3.0 ports. Additionally, there is 1 x HDMI 1.4a output for connecting this NAS to HDMI-compatible devices.

Asustor ships the AS-204RS with the ADM 2.0 operating system, which helps simplify managing your NAS, as well as accessing and sharing data. Asustor also lets users download and install add-on packages that are designed for individual or business needs. A variety of RAID modes are supported, which help provide users with data redundancy, speed, or a combination of both. Supported RAID modes include RAID 0, 1, 5, 6, and 10.

For those who use virtual environments such as VMware, Citrix and Hyper-V, the AS-204RS provides cross-platform file sharing, allowing you to easily connect to your NAS device if you are using Windows, Mac OS, UNIX, Linux, or BSD. Using backup utilities such as Backup Plan and Apple Time Machine you can easily backup data from a Windows PC or Mac directly onto NAS server. Also featured is a Network Recycle Bin. All deleted files will be moved to this bin, allowing you to restore virtually any accidentally deleted files. Moreover, it comes with service LED indicators on both the front and back of the device. After pushing the service LED button located on the front of the device, the corresponding service LED indicator on the back of the device will light up so that the NAS may easily identified within a rack. The AS-204RS 4-Bay SMB NAS Server with 1U/2U Rail Kit operates on 100-240 VAC and includes an AC power cord, 2 x RJ-45 LAN (Cat 5e) cables, 16 x flat head screws (for 3.5" HDDs), 16 x flat head screws (for 2.5" HDDs), and a rail kit for 1U and 2U rackmout systems.

Hardware Maintenance - Service LED Indicator
Engineers often have trouble finding a specific server needing maintenance when faced with numerous servers in a server rack. All Asustor rackmount NAS devices come with service LED indicators on both the front and back of the device. After pushing the service LED button located on the front of the device, the corresponding service LED indicator on the back of the device will light up. Now engineers will be able to quickly locate the device without having to count the screws on their server rack or guess the position of the device. Furthermore, the service LED indicator can be turned on and off from within the ADM interface
