The D-Link xStack Storage Area Network (SAN) Arrays (DSN-3200 & DSN-3400) are 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 capable of supporting over 11TB raw capacity using 750GB hard drives (and even higher capacity hard drives as they are introduced), the DSN-3000 Arrays 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 Fiber 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 signifcantly reduced. IP SANs based on iSCSI technology can leverage existing and familiar Ethernet standards to provide speeds of up to 1160MBytes bandwidth with the DSN-3400.
A Choice of Host Interfaces – 1GbE or 10GbE
The DSN-3200 provides eight 1GbE ports and supports IEEE 802.3ad Link Aggregation Groups (LAG) for full offoad capability so that all eight ports can be grouped together, totaling up to 850MBytes bandwidth, for increased throughput and redundancy. The DSN-3400 provides the industry’s frst built-in, fully integrated 10GbE interface in the XStack cost effective solution. Providing up to 1160MBytes bandwidth and providing a high performance alternative to the 4Gbps Fiber Channel.
System-on-a-Chip (SoC) Implementation
By utilizing a SoC design, the DSN-3000 Series SAN Arrays combine both networking and storage functions into a single specialized Application Specifc Integrated Circuit (ASIC). The SoC solution combines 10Gbps iSCSI, TCP & IP offoad, embedded processors, and a storage virtualization frmware 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-3000 line 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 Effciency
The DSN-3000 Series SAN Array platform features 15 hot swappable Serial ATA (SATA) disk drive bays supporting over 11TB raw capacity using 750GB hard drives (and even higher capacity hard drives as they are introduced) in RAID level 0, 1, 1+0 and 5 confgurations. 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 confgure and monitor their SAN storage sub-systems.
