The D-Link DSN-6000 Series iSCSI SAN array is a highly available, data center-class network storage solution in a 2U rackmount form factor. The DSN-6000 Series currently supports 36TB of raw capacity using 3TB drives (and even greater capacity as larger disk drives become available), and overall scalability to 180TB using the DSN-6020 Expansion Enclosure.

Integrating xStack storage architecture, the DSN-6000 Series supports services for applications demanding high throughput, scalability and flexible storage planning. All DSN-6000 storage solutions are supplied complete with snapshot, volume cloning and remote replication capabilities, without the need for costly software licenses. Also, each RAID controller is equipped with 4GB cache to ensure maximum read and write performance right out of the box.

The DSN-6000 Series can be easily implemented as primary storage, as secondary storage to supplement an existing infrastructure, or as a near line storage device to improve backup and recovery times. Using the intuitive and integrated management GUI, the DSN-6000 Series arrays can be seamlessly incorporated in both Physical and Virtual Server environments.
