DSN-2100-10EOL EOS
Kirjeldus
The D-Link DSN-2100 xStack Storage Area Network (SAN) Array is designed to provide a smaller, more value oriented solution for entry-level and SMB customers. The heart of the DSN-2100 is based on the same powerful System-on-a-Chip (SoC) design found in larger arrays such as the DSN-3000 series of products, but housed in a smaller chassis. Utilizing a 10Gbit iSCSI SoC solution that can handle over 80,000 I/Os per second and capable of supporting 8TBs of raw capacity using 1TB hard drives (and even higher capacity hard drives as they are introduced), the DSN-2100 SAN Array can easily be implemented as nearline storage or as a supplement to your primary backup and recovery device. This evolutionary advancement in performance is a testament to the tightly integrated xStack Storage architecture and is a sharp contrast to the discrete implementation of competing products.
iSCSI for IP Networks
SAN has been traditionally reserved for Fibre Channel networks until the recent introduction of iSCSI that extends 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 signifcantly reduced. iSCSI SANs can leverage the Ethernet infrastructure and standards which are quite familiar to your IT staff.
Four 1GbE Interfaces
The DSN-2000 Series SAN Array implements four 1GbE ports and supports IEEE 802.3ad Link Aggregation Groups (LAG) for full offoad capability so that all four ports can be grouped together, totaling up to 425MB/s bandwidth, for increased throughput and redundancy.
System-on-a-Chip (SoC) Implementation
By utilizing a SoC design, the DSN-2000 Series SAN Arrays combine both networking and storage functions into a single specialized Application Specifc Integrated Circuit (ASIC). The SoC solution combines 10Gbps iSCSI, TCP & IP offoad, embedded processors, and storage virtualization frmware onto a single chip. The tight integration of these functions eliminate interoperability, timing, and support issues found in competitive products that offer “discrete implementation” wherein a chassis, a main motherboard, a RAID storage controller, iSCSI software or controller, network interface cards, and operating system software are choosen separately and then assembled. The DSN-2000 Series SAN Array outperforms these discrete implementations and does so at a lower price point. It also delivers mission critical data quickly with state-of-the-art reliability.
RAID for Effciency
The DSN-2000 Series SAN Array platform features 8 hot swappable Serial ATA (SATA) disk drive bays supporting 8TB raw capacity using 1TB hard drives (and even higher capacity hard drives as they are introduced) in RAID level 0, 1, 1+0 and 5 confgurations. 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 storage network management. Boasting a rich set of management features, this suite of utilities allow monitoring and control of your SAN via the SMI-S (Storage Management Initiative) command set. Combined with an embedded secure server, users will be able to remotely confgure and monitor their SAN storage subsystems.
Advanced Management Features
The DSN-2000 Series SAN Array provides additional advanced features for effcient management of network storage and optimal performance.
Cache Management: Provides adaptive and persistent cache management. This provides write-back, write-through, write coalescing, and multi-stream read-ahead on a volume basis. This optimizes cache utilization and performance in an application dependent manner.
