500MHz CPU and 256MB DDRII large-sized memory out performs other traditional NAS models. This Linux embedded All-in-one Network Attached Storage Server is specifically designed for business users who need fast performance, mass storage, and useful server features. RAID 5 is the most cost effective data protection which allows one drive failure with the system running. RAID 6 allows the failure of maximum two drives to offer business a more advanced data protection.
The flexible RAID Expansion and Migration features lower the total cost of ownership. With Online RAID Capacity Expansion, users can select to purchase the most cost-effective hard drives for initial server setup and upgrade to larger ones in the future. All the stored data will be kept and seamlessly moved to the newly installed hard drives without turning off the server. With Online RAID Level Migration, users can start with one drive and add more to upgrade the RAID level in future with all data retained.

Supports multiple file sharing protocols for users to share files across Linux, Unix, Mac, and Windows platforms. Abundant valuable server functions including File Server, FTP Server, and Printer Server, etc., are supported to satisfy the business needs. Meanwhile, Windows ADS (Active Directory Service) is supported to help create an easy-to-access environment and lower the maintenance cost. With the dual support of MySQL and SQLite, SMB & SOHO users can easily set up their own web and database servers. Also, encrypted remote replication and backup to external devices are supported to enhance data protection. Various data storage and management mechanisms- FTP server with SSL/TLS encrypted technology, SSH login, and web page SSL login enable users to transfer, store, and share data securely.

Silent fan and power-saving design is excellent for long-term operation and deployment in small business environment without server room. The hot-swap design is supported for replacing failed hard drive of a RAID configuration without turning off the server to ensure non-stop services and minimize maintenance cost and effort. Besides, the HDD S.M.A.R.T. provides complete information of the hard drive status to prevent potential physical drive failure. The comprehensive log system summarizes the detail data access records and connection status to server administrator. All error and warning messages can also be sent via e-mail alerts for ease of maintenance.

When HDD failure occurs, the administrator can be alerted by e-mail alarm and LED indication. The failed drive can be replaced by hot swapping without turning off the server. The intelligent data rebuilding features allow users to the new drive without suffering from any system downtime.

Self-Monitoring Analysis and Reporting Technology enables users to monitor the status of hard disk drive and check the potential problems. This tool helps to prevent the unexpected failure of hard disk and avoid critical data loss. The embedded HHS Technology supports disk checking and bad blocks scanning to prevent potential data loss.

Logs of connections to NAS via samba, FTP, AFP, HTTP, HTTPS, Telnet, and SSH, and networking services accessed by online users are all recorded. Server managers can monitor the status of NAS closely.

Data backup may be time and effort-consuming for most users. The enclosed backup software provides users enterprise-class technology to make backup extremely simple and efficient! The intelligent automatic backup software is provided for users to perform real-time synchronization or schedule backup from multiple PCs to NAS. Additionally, the NAS data can also be backed up to external FAT format hard drive. Other backup software, e.g. Acronis True Image, CA BrightStor ARCserver Backup, and EMC Retrospect are supported.

With Windows ADS (Active Directory Service) support, you can deploy your NAS in small business environment easily! It enables Windows domain users to easily access the shared data with the Active Directory authentication. This saves server manager's time and effort in creating groups and accounts and lowers the maintenance cost by centralized management.

File sharing across Windows, Mac, Linux, and Unix environments is supported.

• Data stored on NAS is well protected: Server manager can create user ID and password, and define the authority and quota of each user.
• IP filter control: Users can allow or deny specified IP connections to NAS.
• SSL Security (HTTPS): NAS can be accessed and configured by web browser securely.
• Remote login NAS by SSH (secure shell) or Telnet connection.
• Secure FTP: Share and transmit your data over SSL/TLS (Explicit) encryption. Passive FTP port range setup is also supported.
• Smart FTP policy control: The maximum number of all FTP connections and a single account can be configured.
• Encrypted remote replication: Data on NAS can be backed up to another NAS over the Internet securely.

Server manager can create user ID and password, and define the authority and quota for each user.

If you have trouble sending large files by e-mail due to the limited capacity, you can establish your own FTP server. You can manage the access authority of the FTP server and share your files with your friends or customers easily in a few steps.

Encrypted remote replication provides high level of data protection. Files can be backed up from one NAS to other NAS in remote locations. Advanced options including data compression, block-level incremental backup, and data synchronization are supported to optimize the bandwidth and time for data backup.

With the built-in phpMyAdmin, Joomla! and dual support of MySQL and SQLite, SMB & SOHO users can easily set up their own web server. With the editable php.ini support, there is no need of going through all the hassles of setting up a web server. You can either develop programs by yourself or download a variety of open-sourced applications, such as online shops, forums, blogs, etc., over the Internet.

This is the most affordable choice as a standalone database server for system integrators. It can be installed as a database server of another web server in remote site or as an additional backup database server to achieve system redundancy.

You can share your printer device over the network by connecting up to 3 USB printers and enabling the printer sharing function

APC and MGE UPS are supported. This provides power during power failure allowing users to store data when power outage occurs during data transfer. This energy efficient NAS consumes only 50W in operation and only 18.8W in sleep mode.

Server Managers can hide or show certain folders in the directories for some security reasons while creating the folders for the first time.

When a USB device such as digital camera, digital camcorder, or pen drive is connected to the front panel USB port, data in the USB device can be backed up to NAS automatically by simply pressing the USB copy button. An external storage device can be connected to USB port for alternative data backup.

Allows users to easily download, upload, and manage the files on the server by web browser.

Can you imagine if you delete an important file on the NAS by mistake and lose it forever? You don't need to worry now! The files deleted from the network shares of the NAS will be moved to a particular recycle bin folder. You can restore your data anytime in case of unintended file deletion.

Dynamic DNS (DDNS) is supported. You can register a unique domain name from a DDNS service provider and assign it to your NAS. There is no more need to remember a lengthy IP address!
