DSN-2100-10

iSCSI SAN Array

xStack Storage® 4x1GbE iSCSI SAN Array with 8 SATA Bays

Introduction

D-Link’s DSN-2100-10 iSCSI SAN array is an entry-level

network storage solution in a 2U rackmount form

factor, ideal for small to medium sized businesses.

The heart of the DSN-2100-10 is a powerful 10Gbit

iSCSI System-on-a-Chip (SoC) capable of handling

over 80,000 I/Os per second.

The DSN-2100-10

currently supports 16TB of raw capacity using 2TB

drives.

The DSN-2100-10 can be easily implemented

as nearline storage or as a supplemental backup

platform for quick restores.

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 significantly reduced.

iSCSI SANs leverage the

Ethernet infrastructure and standards that are already

familiar to most IT personnel.

Four 1GbE Interfaces

The DSN-2100-10 supports Multi-path I/O (MPIO),

Multiple Connections per Session (MCS), and Link

Aggregation Groups (LAG) for unmatched network

flexibility, performance and resiliency, allowing its

four 1GbE data ports to be grouped together for up

to 425MB/s bandwidth.

System-on-a-Chip (SoC) Implementation

By utilizing a SoC design, the DSN-2100-10 combines

both networking and storage functions into a

single specialized Application Specific Integrated

Circuit (ASIC).

This SoC combines 10Gbps iSCSI,

TCP & IP offload, embedded processors and storage

virtualization firmware onto a single chip.

The

tight integration of these functions eliminates

interoperability, timing and support issues found

in competitive products that offer a “discrete

implementation” wherein various components are

selected separately, then assembled.

RAID support

The DSN-2100-10 features eight hot swappable Serial

ATA (SATA) disk drive bays and is capable of supporting

16TB of raw capacity using 2TB drives in RAID level

0, 1, 1+0 and 5 configurations (striped sets, mirrored

sets, striped mirrored sets and parity sets) for data

protection and performance.

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-Specification (SMI-S) command set.

With

a secure server, users can remotely configure and

monitor their SAN arrays over the Internet.

Advanced Management Features

The DSN-2100-10 also provides an advanced set

of features for efficient management and optimal

storage performance.

For the fastest RAID performance offered 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-dependant

manner.

Volatile cache data protection is afforded 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
