D-Link, xStack 8x1GbE iSCSI SAN Array with 15 Drive Bays (w/o Drives), 3U Chassis, with Trays.
MODEL- DSN-3200-10 VENDOR- D-LINK

FEATURES- xStack 8 x 1GbE iSCSI SAN Array
The D-Link xStack Storage Area Network (SAN) Array DSN-3200 is
designed to provide a reliable network data storage solution for
customers in entry-level and SMB segments. Utilizing a 10Gbit iSCSI
System-on-a-Chip (SoC) solution that can handle over 65,000 I/Os
per second and up to 6 Terabytes of storage capacity, the DSN-3200
Array can easily be implemented as nearline storage to supplement
your primary IP network storage solution or be used as a basic
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 products.
* 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 (behind server-based) 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.
* High Performance iSCSI Interface
The DSN-3200 provides eight 1GbE ports and supports IEEE 802.3ad Link
Aggregation Groups (LAG) for full offload capability so that all eight
ports can be grouped together, totaling 850MBytes bandwidth, for
increased throughput and redundancy.
* System-on-a-Chip (SoC) Implementation
By utilizing a SoC design, the DSN-3200 SAN Array 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 a storage
virtualization firmware stack 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 picked separately and then assembled. The
DSN-3200 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-3200 SAN Array platform features 15 hot swappable Serial ATA
(SATA) disk drive bays that support RAID levels 0, 1, 5, and 10
configurations with storage capacity of up to 6 Terabytes. 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 allows 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-3200 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.
- 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.
- QoS: Supports IEEE 802.1p Quality of Service (QoS) to efficiently
handle time sensitive network packets.
- Volume Virtualization: The DSN-3200 SAN Array has a storage
management software stack 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, 5 and JBOD (striped sets,
mirrored sets, parity sets, striped mirrored sets and JBOD)
- Micro Rebuilds: Provides protection against unresponsive SATA
commands by forcing a response within a preset time limit.
