Sorry, this product is no longer available, please contact us for a replacement.


Small and medium businesses face an ever increasing need for storage consolidation, document sharing and data backup. D-Link’s DNS-1250 series (DNS-1250-04 and DNS-1250-06) ShareCenter® Pro 1250 Network Storage device addresses these requirements, and provides a multitude of advanced options for managing and securing important files.

Setup and configuration of the DNS-1250 series can be completed in a matter of minutes with our simple and easy to use One Click Setup and intuitive Web Based Interfaces.

Unified Storage Solution
The DNS-1250 series is a unified solution that provides iSCSI and NAS functionalities including MPIO and LUN-masking. It boasts strong iSCSI write performance, greater than many competing products. It also provides versatile RAID support. It features Serial ATA (SATA) disk drive bays (DNS-1250-04: four bays, DNS-1250-06: six bays) and supports volumes in RAID level 0, 1, 5, 6, 10, JBOD and Standard Mode configurations (the DNS-1250-06 also supports RAID levels 30 & 50). Additionally, S.M.A.R.T. disk diagnostics help to ensure data integrity through monitoring of the hard drives. Any hard drive problems detected can be dealt with by Predictive Data Migration (PDM) which moves data from an affected drive to a healthy drive to ensure no loss of data.

NAS File Server
Small and Medium Businesses will appreciate the DNS-1250 series NAS file server which takes advantage of the accelerated performance of the Intel Atom Dual-Core processor. Providing up to 9000 MIPS of computing power and 2GB of cache memory, the DNS-1250 series is able to provide the performance required for your business and its future growth with throughput up to 210MB/s in iSCSI applications.

Virtual Disk Drive (VDD) Expansion
Virtual Disk Drive (VDD) expansion allows the ShareCenter® Pro 1250 to attach up to eight external iSCSI storage targets found on the local network, and use them as virtual disks for additional storage volumes.

Advanced Security
Account management features include the ability to manage users & groups and their read/write permissions, create users, groups, and iSCSI targets with password authentication. Additionally, VLAN tagging support combined with AES encryption keeps files secure. The DNS-1250 series implements CHAP authentication, system firewall and IP blocking to guarantee secure access to the storage system.

A Variety of Backup Options
The DNS-1250 series offers a comprehensive range of backup options which allow administrators and users to control how, when and where their data is stored. Use the USB ports to back up folders from NAS to a flash drive. Users can also take a volume snapshot, back up to Cloud storage, or remotely back up to a server by using an rsync backup utility. Many third-party backup solutions like Acronis Backup & Recovery are also supported.

iSCSI for IP Networks
iSCSI offers fast access performance thanks to block-level data transfer. iSCSI targets appear as a local drive on a client PC or host server. Operations such as configuration, provisioning, and backup can be handled by the administrator in the same way they would be for direct-attached storage (DAS). By utilizing existing Ethernet technology, the cost associated with separate host bus adapters and the per-Gigabyte cost for storage can be significantly reduced when compared versus the Fibre-Channel alternative.

Share Printers and USB Storage
USB connectivity provides the option to connect a printer to the ShareCenter® Pro 1250 and utilize it as a print server, or to connect devices such as hard drives and flash storage to share on your network.

Green Features Save Energy
The DNS-1250 series supports Massive Array of Idle Disks (MAID 2.0) technology which enables significant power savings. It does this by automatically switching off disk drives that are not in active use. The DNS-1250 series is also 80 Plus certified. 80 Plus certification is granted to products that have more than 80% energy efficiency at certain levels of rated load. This enables the ShareCenter® Pro 1250 to run more efficiently by using less electricity, allowing it to run cooler and with reduced operating costs.

Convenient Graphical User Interface
The user interface is clean, intuitive, and professional, which dramatically increases usability. Information and functions are easily seen and found in a clear interface which users will be able to manage without requiring special IT knowledge.
