The heart of the DSN-5000 series is a powerful 10Gbit iSCSI System-on-a-Chip (SoC) capable of handling over 80,000 I/Os per second. The DSN-5000 series supports 24TB of raw capacity using 2TB drives and overall scalability to 168TB (DSN-5210-10 and DSN-5410-10). The DSN-5000 series can be easily implemented as a supplemental backup platform for quick restores, as secondary online storage, or as bandwidth-demanding primary storage for security surveillance and A/V applications. A Choice of Host Interfaces - 1GbE or 10GbE The DSN-5110-10 and DSN-5210-10 both support Multi-path I/O (MPIO), Multiple Connections per Session (MCS), and Link Aggregation Groups (LAG) for unmatched network flexibility, performance and resiliency, allowing their 1GbE data ports to be grouped together for up to 425MB/s or 850MB/s bandwidth, respectively. The DSN-5410-10 utilizes a built-in, fully integrated 10GbE interface as a high performance alternative to 8Gbps Fibre Channel, for up to 1160MB/s bandwidth. High Availability (HA) The DSN-5110-10, DSN-5210-10 and DSN-5410-10 primary arrays, based on a single controller, each provide an ideal platform for nearline storage requirements such as disk-to-disk backup, data archiving and video surveillance. With the addition of a secondary controller (DSN-510 for the DSN-5110-10, DSN-520 for the DSN-5210-10 and DSN-540 for the DSN-5410-10) the DSN-5000 series can provide the failover and redundancy capabilities required for mission critical scenarios such as Virtual Machine (VM) shares, database applications, Online Transactional Processing (OLTP), email applications, storage consolidation and your other primary storage needs. Expansion Options The DSN-5110-10, DSN-5210-10 and DSN-5410-10 primary arrays each support 12 internal SAS/SATA1 hard drives and with the addition of up to three DSN-5000-10 expansion arrays for the DSN-5110-10, and up to six DSN-5000-10 expansion arrays for the DSN-5210-10 and DSN-5410-10, can scale to a total of 96TB and 168TB raw storage capacity respectively. For high availability operation, a secondary I/O board, DSN-500, is installed in the DSN-5000-10 expansion array. 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. System-on-a-Chip (SoC) Implementation By utilizing a SoC design, the DSN-5000 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
