The DSN-5000 Series provides an advanced graphical user interface with "4-click" installation along with additional advanced features for efficient management of network storage and optimal performance.
Cache Management provides write-back, write-through, write coalescing and multi-stream read-ahead on a volume basis, optimizing 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, 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.
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 is 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 hard drive commands by forcing a response within a preset time limit.
If you are looking for a cost-effective block-based storage solution for your nearline storage applications with a clear path to expanded storage capacity and high availability (HA) for mission critical applications, the DSN-5000 Series has a solution for you.
Simplified common setup and management GUI
All of the D-Link xStack Storage products share a common easy-to-use configuration and management GUI console that allows you to manage multiple units from a single screen. You will have your SAN out of the box and ready to go in a few minutes.
Flexible drive configuration
Hard drives of various sizes may be used within the same array and can be configured with multiple RAID types and volume segments on a single drive. Typical SAN arrays allow one size of drive with a single RAID type and volume per drive.
Embedded centralized storage management
The embedded, user-friendly IP-SAN Device Manager (IDM) provides comprehensive network storage 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, you will also be able to remotely configure and monitor multiple D-Link SAN storage subsystems.
