D-Link's DSN-4100 iSCSI SAN array 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-4100 is a powerful 10 Gbit iSCSI System-on-a-Chip (SoC) capable of handling over 80,000 I/OS per second. The DSN-4100 supports 32 TB of raw capacity using 2 TB 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 Fiber 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 Fiber 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.
The DSN-4100 iSCSI SAN array 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 bandwidth.
The DSN-4100 primary array supports 16 internal SAS/SATA hard drives and with the addition of up to four DSN-4000 expansion arrays, can scale to a total of 160 TB of raw storage capacity using 2 TB drives.
System-on-a-Chip (SoC) implementation
By utilizing a SoC design, the DSN-41000 combines both networking and storage functions into a single specialized Application Specific Integrated Circuit (ASIC). This SoC combines 10 Gbps iSCSI, TCP and 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.
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 supports S.M.A.R.T. disk diagnostics, and non-destructive 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 featuresProduct Highlights
The DSN-4100 also provides an advanced set of features for efficient management and optimal storage performance. The DSN-4100 supports jumbo frames and VLAN tagging to segregate traffic into isolated zones for secure access, improving network throughput and reducing CPU overhead. An iSCSI SAN array can prove to be a valuable tool to supplement a network storage foundation. Whether providing a low-cost block-based solution for data backup and recovery, replacement of Direct Attached Storage (DAS), providing secondary online storage, or providing up to 425 MB/s bandwidth for security surveillance and video post-production applications, the DSN-4100 may provide the performance and functionality needed.
