D-Link DSN-4200 Hardware Reference Guide for DSN-4000 - Page 9

Chapter 1 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. 1.1 Models The D-Link xStack Storage DSN-4000 series storage array is available in various models. The models differ according to the speed and host network interface, as well as the number of drive bays. Table 1-1 lists the various DSN-4X00 Primary Array models. Table 1-1.
