DSN-1000 Series Managed SAN Solutions

D-Link 4x1GbE iSCSI SAN Array with 5 SATA Bays

The D-Link® DSN-1100-10 4x1GbE iSCSI SAN Array
provides a smaller, more value-oriented solution for
entry-level and SMB customers. The heart of the
DSN-1100 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, the DSN-1100 is capable of supporting
5TBs of raw capacity using 1TB hard drives (and even
higher capacity hard drives as they are introduced). The
DSN-1100 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 storage architecture
and is a sharp contrast to the discrete implementation of
competing products.

iSCSI for IP Networks

SAN has been traditionally reserved for Fibre Channel
networks until the recent introduction of iSCSI extended 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 that are already familiar to your IT staff.

Four 1GbE Interfaces

The DSN-1100 implements four 1GbE ports that support
IEEE 802.3ad Link Aggregation Groups (LAG) for full offload
capability. This allows all four ports to be grouped together
for up to 425MB/s bandwidth, increasing throughput and
redundancy.

System-on-a-Chip (SoC) Implementation

By utilizing a SoC design, the DSN-1100 combines
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 eliminates interoperability, timing, and support
issues found in competitive products that offer “discrete
implementation” wherein all the various components are
chosen separately and then assembled. The DSN-1100
outperforms these discrete implementations and does so
at a lower price point, while delivering mission-critical
data quickly with state-of-the-art reliability.

RAID for Efficiency

The DSN-1100 features five hot swappable Serial ATA
(SATA) disk drive bays supporting 5TB 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 network storage
management.

Advanced Management Features

The DSN-1100 provides additional advanced features for
efficient management of network storage and optimal
performance.

Technical Specifications

For the fastest RAID performance offered in the industry,
the D-Link 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 afforded via an on-board battery that is
designed to back up to 1GB of cached memory for at least
72 hours.

VLAN Zoning supports IEEE 802.1q VLAN tagging to
segregate traffic into isolated zones for secure access and
jumbo frames, improving network throughput and reducing
CPU overhead.

Volume Virtualization utilizes 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 dissimilar size can be used
to create volumes. Growth can occur without volume
migration or reconstruction. Single drives can contain
multiple and divergent RAID technologies.

RAID Support for RAID Levels 0, 1, 1+0 and 5 (striped sets,
mirrored sets, striped mirrored sets, and parity sets) allows
for different storage options.

Online Capacity Expansion and RAID Level Migration
are performed online 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 provide protection against unresponsive
SATA commands by forcing a response within a preset
time limit.

An iSCSI array can prove to be a valuable tool to supplement
your network storage foundation. Whether providing a
low-cost 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-1100 can meet all of your immediate needs.
