ShareCenter® Pro 1250 - 4-bay & 6-bay NAS/iSCSI Unified
Storage for Small and Medium Businesses
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.
