xStack Storage® 4X1GbE iSCSI SAN Array with 5 SATA BaysEOL
The D-Link® DSN-1100-10 xStack Storage 4x1GbE iSCSI SAN Array provides a smaller, more value-oriented solution for entry-level and SMB customers. The heart of the DSN-1100 is based on the same powerful System-on-a-Chip (SoC) design found in larger arrays such as the DSN-3000 Series of products, but housed in a smaller chassis. Utilizing a 10Gbit iSCSI SoC solution that can handle over 80,000 I/Os per second, the DSN-1100 is capable of supporting 5TBs of raw capacity using 1TB hard drives (and even higher capacity hard drives as they are introduced). The DSN-1100 can easily be implemented as nearline storage or as a supplement to your primary backup and recovery device. This evolutionary advancement in performance is a testament to
iSCSI for IP Networks

RAID for Effciency
Embedded Centralized Storage Management
For the fastest RAID performance offered in the industry, the D-Link 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 that is designed to back up to 1GB of cached memory for at least 72 hours. A write-back or write-through cache memory policy can be selected manually or automatically, depending on the battery’s charge.
VLAN Zoning supports IEEE 802.1q VLAN tagging to segregate traffc into isolated zones for secure access and jumbo frames, improving network throughput and reducing CPU overhead. Volume Virtualization utilizes 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 dissimilar 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 for RAID Levels 0, 1, 1+0 and 5 (striped sets, mirrored sets, striped mirrored sets, and parity sets) allows for different storage options.Online Capacity Expansion and RAID Level Migration are performed online with minimal impact on users. For example, a mirror volume of two drives can easily be converted to a parity volume of three or more drives while users continue to access this storage. Micro Rebuilds provide protection against unresponsive SATA commands by forcing a response within a preset time limit.
An iSCSI array can prove to be a valuable tool to supplement your network storage foundation. Whether providing a low-cost block-based solution for data backup and recovery, replacement of Direct-Attached Storage (DAS) drives, or providing a cost-effective entry-level nearline storage solution, the DSN-1100 can meet all of your immediate needs.
