Higher Capacities for Low-End Arrays

Arthur Cole

Storage arrays intended for small and medium-sized businesses are pushing the capacity envelope, a sign of the increasing reliance of data services beyond the corporate environment.


D-Link Canada is shipping the xStack DNS-2100-10 SAN with a full 8 TB of capacity, powered by the same DSN-3000 iSCSI System-on-Chip (SoC) technology found in the company's higher-end arrays. The system can run more than 80,000 IOPS and is backed by four 1 GbE ports that can be combined for a total bandwidth of 425 MB, and an embedded disk controller that supports RAID Levels 0, 1, 1+0 and 5.


Other features include advanced cache management with write-back, write-through and write-coalescing functions; VLAN zoning under the IEEE 802.1q VLAN tagging standard; and volume virtualization that enables online expansion and volume migration.


The company envisions the system as near-line storage or as a supplement to primary backup and recovery systems.
