Product Highlights
Introduction
D-Link’s DSN-4000 series (DSN-4100 and DSN-4200) iSCSI SAN arrays provide a mid-range
network storage solution in a 3U rackmount form factor, ideal for small and medium sized
enterprises. The heart of the DSN-4000 series is a powerful 10Gbit iSCSI System-on-a-Chip
(SoC) capable of handling over 80,000 I/OS per second. The DSN-4000 series supports
48TB2of raw capacity using 3TB2drives and can be easily implemented as a supplemental
backup platform for quick restores, as secondary online storage, or as bandwidth
demanding primary storage for security surveillance and A/V applications.
iSCSI for IP Networks
Storage Area Networks (SANs) have traditionally been reserved for complex Fibre
Channel networks. The recent introduction of iSCSI has extended the powerful
centralized storage capabilities of SAN technology to IP networks. By utilizing existing
Ethernet technology, the costs associated with Fibre Channel switching, separate
host bus adapters, expensive storage subsystems and administration is signicantly
reduced. iSCSI SANs leverage the Ethernet infrastructure and standards that are already
familiar to most IT personnel.
A Choice of Host Interfaces – Four 1GbE or Eight 1GbE
The DSN-4100 & DSN-4200 iSCSI SAN arrays support Multi-path I/O (MPIO),
Multiple Connections per Session (MCS), and Link Aggregation Groups (LAG) for
unmatched network flexibility, performance and resiliency, allowing their 1GbE
data ports to be grouped together for full line speeds of up to 425MB/s and
850MB/s bandwidth respectively.

System-on-a-Chip (SoC) Implementation
By utilizing a SoC design, the DSN-4000 series combines both networking and storage
functions into a single specialized Application Specic Integrated Circuit (ASIC). This
SoC combines 10Gbps iSCSI, TCP & IP ooad, 12 embedded processors and storage
virtualization rmware onto a single chip. The tight integration of these functions
eliminates interoperability, timing and support issues found in competitive products
that oer a “discrete implementation” wherein various components are selected
separately, then assembled.

(striped sets, mirrored sets, striped mirrored sets and parity sets) for data protection
and performance.
D-Link’s xStack Storage iSCSI SAN arrays support S.M.A.R.T. disk diagnostics, and non-
destructive data migration to prevent disk failure.
Embedded Centralized Storage Management
The embedded, user-friendly IP-SAN Device Manager (IDM) provides a comprehensive
console for system management. Boasting a rich set of management features, this suite
of utilities allows monitoring and control of the SAN array via the Storage Management
Initiative-Specication(SMI-S)commandset.Withasecureserver,userscanremotely
congure and monitor their SAN arrays over the Internet.
Advanced Management Features
The DSN-4000 series also provides an advanced set of features for ecient management
and optimal storage performance.
For the fastest RAID performance oered in the industry, D-Link’s adaptive cache

basis, optimizing cache utilization and performance in an application dependent

cache memory for a minimum of 72 hours. A write-back or write-through cache
memory policy can be selected manually or automatically, depending on the status of
the battery’s charge.
The DSN-4000 series supports jumbo frames and VLAN tagging to segregate trac
into isolated zones for secure access, improving network throughput and reducing
CPU overhead.

D-Link’s volume virtualization technology utilizes the concept of storage
extents, which are the fundamental building blocks used to enable
features such as RAID, online capacity expansion, volume reconguration
and migration. Each disk drive can contain multiple and divergent RAID
congurations instead of requiring dedication to a single RAID set. This
technology allows for the support of mixed disk drive capacities for volume
creation. Volume capacity expansion, volume reconguration, and RAID level
migration are performed online with minimal impact to users. Users can
quickly deploy a SAN using inexpensive SAS or SATA disk drives and simply
add more drives as needed.
An iSCSI SAN array can prove to be a valuable tool to supplement a network
storagefoundation.Whetherprovidingalow-costblock-basedsolutionfordata
backup and recovery, replacement of Direct Attached Storage (DAS), providing
secondary online storage, or providing up to 850MB/s bandwidth for security
surveillance and video post-production applications, the DSN-4000 series may
