מערך אחסון iSCSI SAN מסדרת xStack, עד 8 דיסקים נשלפים SATA-II ו- 4 יציאות ג'יגהביט לרשתדגם לא מיוצר יותר
The D-Link DSN-2100-10 xStack Storage Area Network (SAN) Array is designed to provide a smaller, more value oriented solution for entry-level and SMB customers. The heart of the DSN-2100-10 SAN Array 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 and capable of supporting 8TBs of raw capacity using 1TB hard drives (and even higher capacity hard drives as they are introduced), the DSN-2100-10 SAN Array 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 the tightly integrated xStack Storage architecture and is a sharp contrast to the discrete implementation of competing products.

Recommended hard drives for the DSN-2000 series SAN arrays:
Embedded Centralized Storage Management
Advanced Management Features
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.
Volume Virtualization: The DSN-2100-10 has storage management software 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 and 5 (striped sets, mirrored sets, striped mirrored sets, and parity sets) are supported, allowing different storage options.
Online Capacity Expansion and RAID Level Migration:: Volumes can be expanded and/or migrated to other RAID levels while online and 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: Provides protection against unresponsive SATA commands by forcing a response within a preset time limit.
An iSSCSI 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-2100-10 xStack Storage Area Network (SAN) Array can meet your immediate needs.
