xStack Storage™ iSCSI SAN Arrays
The D-Link DSN-2100-10 xStack Storage Area Network
(SAN) Array is designed to provide a smaller, more value
oriented solution for entry-level and SMB customers. The
heart of the DSN-2000 series SAN Array is based on the
same powerful System-on-a-Chip (SoC) design found in
larger arrays such as the DSN-3000 series of products, but
housed in a smaller chassis. Utilizing a 10Gbit iSCSI SoC
solution that can handle over 80,000 I/Os per second and
capable of supporting 8TBs of raw capacity using 1TB hard
drives (and even higher capacity hard drives as they are
introduced), the DSN-2000 Series SAN Array can easily
be implemented as nearline storage or as a supplement to
your primary backup and recovery device. This evolutionary
advancement in performance is a testament to the tightly
integrated xStack Storage architecture and is a sharp
contrast to the discrete implementation of competing

iSCSI for IP Networks
SAN has been traditionally reserved for Fibre Channel
networks until the recent introduction of iSCSI that
extends this powerful yet simple centralized backend
storage system to IP networks. By utilizing existing
Ethernet technology, the cost associated with separate
host bus adapters and the per-Gigabyte cost for storage is
significantly reduced. iSCSI SANs can leverage the Ethernet
infrastructure and standards which are quite familiar to your
IT staff.

Four 1GbE Interfaces
The DSN-2000 Series SAN Array implements four 1GbE ports
and supports IEEE 802.3ad Link Aggregation Groups (LAG)
for full offload capability so that all four ports can be grouped
together, totaling up to 425MB/s bandwidth, for increased
throughput and redundancy.
System-on-a-Chip (SoC) Implementation
By utilizing a SoC design, the DSN-2000 Series SAN Arrays
combine both networking and storage functions into a single
specialized Application Specific Integrated Circuit (ASIC).
The SoC solution combines 10Gbps iSCSI, TCP & IP offload,
embedded processors, and storage virtualization firmware
onto a single chip. The tight integration of these functions
eliminate interoperability, timing, and support issues found
in competitive products that offer “discrete implementation”
wherein a chassis, a main motherboard, a RAID storage
controller, iSCSI software or controller, network interface
cards, and operating system software are choosen
separately and then assembled. The DSN-2000 Series SAN
Array outperforms these discrete implementations and does
so at a lower price point. It also delivers mission critical data
quickly with state-of-the-art reliability.
RAID for Efficiency
The DSN-2000 Series SAN Array platform features 8 hot
swappable Serial ATA (SATA) disk drive bays supporting 8TB
raw capacity using 1TB hard drives (and even higher capacity
hard drives as they are introduced) in RAID level 0, 1, 1+0
and 5 configurations. You can quickly deploy a SAN using
inexpensive SATA disk drives and, depending on your growing
storage needs, you can simply add more drives as you go.
Embedded Centralized Storage Management
The embedded user-friendly IP-SAN Device Manager (IDM)
provides comprehensive storage network management. Boasting
a rich set of management features, this suite of utilities allow
monitoring and control of your SAN via the SMI-S (Storage
Management Initiative) command set. Combined with an
embedded secure server, users will be able to remotely configure
and monitor their SAN storage subsystems.
Advanced Management Features
The DSN-2000 Series SAN Array provides additional advanced
features for efficient management of network storage and
optimal performance.
Cache Management: Provides adaptive and persistent cache
management. This provides write-back, write-through, write
coalescing, and multi-stream read-ahead on a volume basis.
This optimizes cache utilization and performance in an
application dependent manner.
DSN-2000 Series Managed SAN Solutions
xStack Storage™ iSCSI SAN Arrays
VLAN Zoning: Supports IEEE 802.1q VLAN tagging to segregate
traffic into isolated zones for secure access and jumbo frames
to improve the network throughput and reduce CPU overhead.
Volume Virtualization: The DSN-2000 Series has storage
management software that provides volume virtualization
features by utilizing the concept of storage Extents. Extents are
the fundamental building blocks used to enable features such as
RAID, online capacity expansion and volume migration. Drives
of disimilar size can be used to create volumes. Growth can
occur without volume migration or reconstruction. Single drives
can contain multiple and divergent RAID technologies. Volume
structure can also provide infrastructure for Snapshot copies.
RAID Support: RAID Levels 0, 1, 1+0 and 5 (striped sets,
mirrored sets, striped mirrored sets, and parity sets) are
supported, allowing different storage options.
Online Capacity Expansion and RAID Level Migration:
Volumes can be expanded and/or migrated to other RAID
levels while online and with minimal impact on users. For
example, a mirror volume of two drives can easily be
converted to a parity volume of three or more drives while
users continue to access this storage.
Micro Rebuilds: Provides protection against unresponsive
SATA commands by forcing a response within a preset time limit.
An iSSCSI array can prove to be a valuable tool to supplement
your network storage foundation. Whether providing a lowcost block-based solution for data backup and recovery,
replacement of Direct-Attached Storage (DAS) drives,
or providing a cost-effective entry-level nearline storage
solution, the DSN-2000 Series xStack Storage Area Network
(SAN) Array can meet your immediate needs.
