xStack Storage® 4x1GbE iSCSI SAN Array with 5 SATA Bays
Introduction
D-Link' s DSN-1100-10 iSCSI SAN array is an entry-level
network storage solution in a compact, desktop
form factor, ideal for small businesses. The heart
of the DSN-1100-10 is a powerful 10Gbit iSCSI
System-on-a-Chip (SoC) capable of handling
over 80,000 I/Os per second. The DSN-1100-10
supports 10TB of raw capacity using 2TB drives.
The DSN-1100-10 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 significantly reduced. iSCSI SANs leverage the
Ethernet infrastructure and standards that are
already familiar to most IT personnel.
Four 1GbE Interfaces
The DSN-1100-10 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-1100-10 combines
both networking and storage functions into a single
D SN- 1100- 10 i SC SI SAN Ar ray
specialized Application Specific Integrated Circuit (ASIC).
This SoC combines 10Gbps iSCSI, TCP & IP offload,
12 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
D-Link's xStack iSCSI SAN arrays support RAID level
0, 1, 1+0 and 5 configurations (striped sets, mirrored
sets, striped mirrored sets and parity sets) for data
protection and performance.
D-Link supports S.M.A.R.T., disk scan, 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-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-1100-10 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
