High Performance iSCSI Interface • DSN-4100: Four 1GbE Data Ports • DSN-4200: Eight 1GbE Data Ports Storage Network Management • Web-based, Wizard-driven IP SAN Device Manager (IDM) for easy Management • Remote Monitoring and Configuration • CHAP Authentication Helps Halt Intruders • SSL Security to Management Console Drive Expansion • DSN-4000 Expansion Array • For use with DSN-4100 and DSN-4200 Primary SAN Arrays • Provides 16 Hot-Swap Drive Bays • Up to four expansion arrays supported for 80 drives total DSN-4000 Series iSCSI SAN Array Expansion Options The DSN-4100 and DSN-4200 primary arrays each support 16 internal SAS/SATA hard drives and with the addition of up to four DSN-4000 expansion arrays, can scale to a total of 160TB of raw storage capacity using 2TB drives. System-on-a-Chip (SoC) Implementation By utilizing a SoC design, the DSN-4000 series combines both networking and storage functions into a single specialized Application Specific Integrated Circuit (ASIC). This SoC combines 10Gbps iSCSI, TCP & IP offload, 12 embedded processors and storage virtualization firmware onto a single chip. The tight integration of these functions eliminates interoperability, timing and support issues found in competitive products that offer a "discrete implementation" wherein various components are selected separately, then assembled. RAID support D-Link's xStack Storage iSCSI SAN arrays support RAID level 0, 1, 1+0 and 5 configurations (striped sets, mirrored sets, striped mirrored sets and parity sets) for data protection and performance. D-Link's xStack Storage iSCSI SAN arrays support S.M.A.R.T. disk diagnostics, and nondestructive data migration to prevent disk failure. Embedded Centralized Storage Management The embedded, user-friendly IP-SAN Device Manager (IDM) provides a comprehensive console for system management. Boasting a rich set of management features, this suite of utilities allows monitoring and control of the SAN array via the Storage Management Initiative-Specification (SMI-S) command set. With a secure server, users can remotely configure and monitor their SAN arrays over the Internet. Advanced Management Features The DSN-4000 series also provides an advanced set of features for efficient management and optimal storage performance. For the fastest RAID performance offered in the industry, D-Link's adaptive cache management provides write coalescing and multi-stream read-ahead on a volume basis, optimizing cache utilization and performance in an application dependent manner. Volatile cache data protection is afforded via an on-board battery supporting cache memory for a minimum of 72 hours. A write-back or write-through cache memory policy can be selected manually or automatically, depending on the status of the battery's charge. The DSN-4000 series supports jumbo frames and VLAN tagging to segregate traffic into isolated zones for secure access, improving network throughput and reducing CPU overhead.
