The heart of the DSN-2100-10 is a powerful 10Gbit iSCSI System-on-a-Chip (SoC) capable of handling over 80,000 I/Os per second. The DSN-2100-10 currently supports 16TB of raw capacity using 2TB drives. The DSN-2100-10 can be easily implemented as nearline storage or as a supplemental backup platform for quick restores. iSCSI for IP Networks Storage Area Networks (SANs) have traditionally been reserved for complex Fibre Channel networks. The recent introduction of iSCSI has extended the powerful centralized storage capabilities of SAN technology to IP networks. By utilizing existing Ethernet technology, the costs associated with Fibre Channel switching, separate host bus adapters, expensive storage subsystems and administration is significantly reduced. iSCSI SANs leverage the Ethernet infrastructure and standards that are already familiar to most IT personnel. 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 The DSN-2100-10 features eight hot swappable Serial ATA (SATA) disk drive bays and is capable of supporting 16TB of raw capacity using 2TB drives in RAID level 0, 1, 1+0 and 5 configurations (striped sets, mirrored sets, striped mirrored sets and parity sets) for data protection and performance. 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. Four 1GbE Interfaces The DSN-2100-10 supports Multi-path I/O (MPIO), Multiple Connections per Session (MCS), and Link Aggregation Groups (LAG) for unmatched network flexibility, performance and resiliency, allowing its four 1GbE data ports to be grouped together for up to 425MB/s bandwidth. System-on-a-Chip (SoC) Implementation By utilizing a SoC design, the DSN-2100-10 combines both networking and storage functions into a single specialized Application Specific Integrated Circuit (ASIC). This SoC combines 10Gbps iSCSI, TCP & IP offload, embedded processors and storage Advanced Management Features The DSN-2100-10 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 readahead on a volume basis, optimizing cache utilization and performance in an application-dependant 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
