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

32TB of raw capacity using 2TB drives 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 por ts to be grouped together for full line speeds of up to 425MB/s and

850MB/s bandwidth respectively.

The DSN-4100 and DSN-4200 primary arrays each support 16 internal SAS/SATA hard

drives and with the addition of up to four DSN-4000 expansion arrays, can scale to a

total of 160TB of raw storage capacity using 2TB drives.

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.

RAID support

D-Link’s xStack Storage iSCSI SAN arrays support RAID level 0, 1, 1+0 and 5 congurations

(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

management provides write coalescing and multi-stream read-ahead on a volume

basis, optimizing cache utilization and performance in an application dependent

manner. Volatile cache data protection is aorded via an on-board battery supporting

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.

DSN-4000 Series iSCSI SAN Array

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

provide the performance and functionality needed.
