D-Link's 5-Bay iSCSI SAN Enclosure with 4 Gigabit ports provides an entry-level, value-oriented solution for SMB customers. In a small chassis that can fit anywhere, it fully integrates with the same Ethernet infrastructure as the data network, saving considerable cost compared with the Fiber Channel technology traditionally used for Storage Area Networks. The DSN-1100 features five hot swappable Serial ATA (SATA) disk drive bays supporting 5 TB raw capacity using 1 TB hard drives (and even higher capacity hard drives as they are introduced) in RAID level 0, 1, 1+0 and 5 configurations.
Built on a powerful System-on-a-Chip (SoC) design usually found in larger arrays, it can handle over 80,000 I/Os per second. This single-chip solution eliminates interoperability, timing, and support issues found in competitive products that offer "discrete implementation" wherein all the various components are chosen separately and then assembled. The DSN-1100 outperforms these discrete implementations at a lower price point.
The DSN-1100 implements four Gigabit Ethernet ports that can be grouped together for up to 425MB/s bandwidth, increasing throughput and redundancy. Other features include volatile cache data protection via an on-board battery designed to back up up to 1GB of cached memory for at least 72 hours, support for IEEE 802.1Q VLAN tagging and jumbo frames, volume virtualization with storage Extents. The embedded, user-friendly IP-SAN Device Manager (IDM) provides comprehensive network storage management.
iSCSI for IP networks
SAN has been traditionally reserved for Fiber Channel networks until the recent introduction of iSCSI extended this powerful yet simple centralized backend storage system to IP networks. By utilizing existing Ethernet technology, the cost associated with separate host bus adapters and the per-Gigabyte cost for storage is significantly reduced. iSCSI SANs can leverage the Ethernet infrastructure and standards that are already familiar to your IT.
Four 1GbE interfaces
The DSN-1100-10 implements four 1GbE ports that support IEEE 802.3ad Link Aggregation Groups (LAG) for full offload capability. This allows all four ports to be grouped together for up to 425MB/s bandwidth, increasing throughput and redundancy.
System-on-a-Chip (SoC) implementation
By utilizing a SoC design, the DSN-1100-10 combines both networking and storage functions into a single specialized Application Specific Integrated Circuit (ASIC). The SoC solution combines 10Gbps iSCSI, TCP and IP offload, 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 "discrete implementation" wherein all the various components are chosen separately and then assembled. The DSN-1100-10 outperforms these discrete implementations and does so at a lower price point, while delivering mission-critical data quickly with state-of-the-art reliability.
RAID for efficiency
The DSN-1100-10 features five hot swappable Serial ATA (SATA) disk drive bays supporting 5TB raw capacity using 1TB hard drives in RAID level 0, 1, 1+0 and 5 configurations. You can quickly deploy a SAN using inexpensive SATA disk drives and, depending on your growing storage needs, you can simply add more drives as you go.
Embedded centralized storage management
The embedded, user-friendly IP-SAN Device Manager (IDM) provides comprehensive network storage management. Boasting a rich set of management features, this suite of utilities allows monitoring and control of your SAN via the Storage Management Initiative-Specification (SMI-S) command set. Combined with an embedded secure server, users will be able to remotely configure and monitor their SAN storage subsystems.
Advanced management features
The DSN-1100-10 provides additional advanced features for efficient management of network storage and optimal performance.
