D-Link Debuts 'Secondary Server' Arrays

By Stuart J. Johnston

Storage vendor D-Link Monday rolled out a new series of iSCSI SAN arrays designed for use in "secondary server" applications such as disaster recovery, backup, archiving, and surveillance.

The DSN-4000 series is meant for small to medium-sized enterprises to provide cost effective volume virtualization, high transactional and throughput performance, and guaranteed interoperability with the host environment, according to D-Link statements.

D-Link's DSN-4000 series comes in two models -- the DSN-4100 and DSN-4200 xStack Storage iSCSI SAN arrays, which will both be available in a 3U form factor in November.

The DSN-4100 and DSN-4200 support as much as 32 TB of raw storage capacity with 16 SAS/SATA drive bays. Additionally, the DSN-4000 series arrays also support expansion to up to 48 drive bays, which will hold 96 TB of raw capacity, the company said. D-Link has a 16-bay expansion array.

The units are stackable and can handle more than 80,000 input/output operations per second (IOPS) -- fast enough to support audio and video post production, according to D-Link.

Meanwhile, the DSN-4100 provides four 1 GbE data ports with throughput of up to 425 MB per second, while the DSN-4200 provides eight 1 GbE data ports providing throughput of up to 850 MB per second.

"D-Link offers a breadth of networking solutions ranging from IP [Internet Protocol] cameras and surveillance technologies to network switches and wireless access points, to network-attached storage and high-performance iSCSI SAN arrays," the company said.

The D-Link DSN-4100 xStack Storage iSCSI array will start at $4,999.99 while the DSN-4200 xStack Storage iSCSI array will cost $6,199.99. D-Link's optional DSN-4000 16-bay expansion bay will cost $3,199.99. "D-Link underscores its commitment to the storage market with the superior economic value offered through D-Link's affordable solutions, professional support and flexible architecture," Chris Gruber, director of product marketing for storage solutions at D-Link, said in a statement.
