xStack Storage® HA capable 4x1GbE, 8x1GbE or 1x10GbE iSCSI
SAN Array with 12 SAS/SATA
that offer a "discrete implementation" where in
various components are selected separately, then
assembled.
RAID support
D-Link's xStack iSCSI SAN arrays support RAID levels 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
All of the D-Link xStack Storage products share a
common easy-to-use configuration and management
GUI console that allows you to manage multiple units
from a single screen. The intuitive wizards ensure you
will have your SAN out of the box and ready to go in a
few minutes.
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-5000 series 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-dependent manner. Volatile cache
data protection is afforded via an on-board battery
supporting 2GB of cache memory for a minimum of 72
hours. A write-back or write-through cache memory
policy can be selected manually or automatically,
depending on the status of the battery's charge.
The DSN-5000 series supports jumbo frames and
VLAN tagging to segregate traffic into isolated zones
for secure access, improving network throughput and
reducing CPU overhead.
D-Link's volume virtualization technology utilizes the
concept of storage extents, which are the fundamental
building blocks used to enable features such as RAID,
online capacity expansion, volume reconfiguration
and migration. Each disk drive can contain multiple
and divergent RAID configurations instead of requiring
dedication to a single RAID set. This technology allows
for the support of mixed disk drive capacities for volume
creation. Volume capacity expansion and RAID level
migration are performed online with minimal impact to
users. Additionally, volume growth can occur without
volume migration or reconstruction. Users can quickly
deploy a SAN and simply add more drives as needed.
An iSCSI SAN array can prove to be a valuable tool
to supplement a network storage foundation.
Whether providing a low-cost block-based solution
for replacement of Direct Attached Storage (DAS),
providing primary online storage, or providing up
to 1160 MB/s bandwidth for security surveillance,
video editing, video post-production applications,
the DSN-5000 series will provide the performance and
functionality needed.
