The heart of the DSN-4000 series is a powerful 10Gbit iSCSI System-on-a-Chip (SoC) capable of handling over 80,000 I/OS per second. The DSN-4000 series supports 32TB of raw capacity using 2TB drives and 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. 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. A Choice of Host Interfaces - Four 1GbE or Eight 1GbE The DSN-4100 & DSN-4200 iSCSI SAN arrays 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 full line speeds of up to 425MB/s and 850MB/s bandwidth respectively.
