Introduction
D-Link's DSN-4000 series (DSN-4100 and DSN-4200) iSCSI SAN arrays provide a mid-range
network storage solution in a 3U rackmount form factor, ideal for small and medium sized
enterprises. 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
48TB of raw capacity using 3TB drives and can be easily implemented as a supplemental
2 2
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.
