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
