DSN-2000 Series Managed SAN Solutions

xStack Storage™ iSCSI SAN Arrays

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-2000 Series 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-2000 Series xStack Storage Area Network (SAN) Array can meet your immediate needs.
