From the Manufacturer
D-Link's DSN-4000 series iSCSI SAN arrays provide a mid-range network storage solution in a 3U rackmount form factor, ideal for small and medium sized enterprises.
The heart of the DSN-4000 series (DSN-4100/DSN-4200) is a powerful 10Gbit iSCSI System-on-a-Chip (SoC) capable of handling over 80,000 I/OS per second. The DSN-4000 series supports 32TB of raw capacity using 2TB drives and 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.

Embedded Centralized Storage Management
Advanced Management Features
The DSN-4000 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, volume reconfiguration, and RAID level migration are performed online with minimal impact to users. Users can quickly deploy a SAN using inexpensive SAS or SATA disk drives 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 data backup and recovery, replacement of Direct Attached Storage (DAS), providing secondary online storage, or providing up to 850MB/s bandwidth for security surveillance and video post-production applications, the DSN-4000 series may provide the performance and functionality needed.
