Introduction
The xStack Storage DSN-4000 series storage system is an intelligent, high-performance
multiple Gigabit Ethernet storage solution designed for businesses that want to improve the
reliability, availability, serviceability, and performance of their storage systems. It provides
a range of benefits and features from its ability to use familiar, proven, and widespread
networking technologies like IP and Ethernet for storage solutions.
The DSN-4000 series storage system is highly scalable. To add more storage capacity, simply
add additional DSN-4000 expansion arrays to the DSN-4X00 primary array for up to 80 drives.
This plug-and-play approach to storage expansion enables you to form a scalable enterprise
storage grid of many drives quickly and easily.
Based on an Internet Protocol-Storage Area Network (IP-SAN) architecture, the DSN-4X00
primary array is built around D-Link’s iSCSI RAID processor system-on-a-chip and has the
following features:
Up to 80 Serial Attached SCSI (SAS) or Serial Advanced Technical Attachment (SATA) hard
disk drives per system (including DSN-4000 expansion arrays), with a maximum storage
capacity of 2TB per drive
A minimum of 512 MB of System Memory, expandable to 2GB
A minimum of 1024 MB of Buffer Memory, expandable to 4 GB
iSCSI Ethernet Connectors (depending on your specific hardware configuration):
Eight 1-Gigabit RJ-45 connectors
Four 1-Gigabit RJ-45 connectors
A 10/100/1000 Mbps Ethernet management port
One SAS expansion connector for attaching additional DSN-4000 JBOD expansion arrays
One 3.5mm RS-232-C stereo mini-jack diagnostic port for troubleshooting purposes
Complete configuration and management of the storage system are available through the
intuitive, graphical-based Management Center software.
