D-Link DSN-6510
12-Bay 2x10GbE + 2xGbE H.A. Capable iSCSI SAN Storage Array

Overview:

D-Link’s DSN-6510 iSCSI SAN array is a fully redundant, data centre-class network storage solution in a 2U rackmount form factor. The DSN-6510 currently supports 72TB of raw capacity using 6TB drives (and even greater capacity as larger disk drives become available), and overall scalability up to 1.5PB using additional DSN-6020 expansion JBODs. D-Link’s DSN-6510 provides 10GE host interface connectivity. The DSN-6000 Series storage architecture supports services for applications demanding high throughput, scalability and flexible storage planning. The DSN-6000 Series can be easily implemented as primary storage, as secondary storage to supplement an existing infrastructure, or as a nearline storage device to improve backup and recovery times. Using the intuitive and integrated management GUI, the DSN-6000 Series Arrays can be seamlessly incorporated in both Physical and Virtual Server environments.

High Availability
The DSN-6000 Series can provide the failover and redundancy capabilities required for mission critical scenarios such as Virtual Machine (VM) shares, database hosting, Online Transactional Processing (OLTP), email applications, storage consolidation and other primary storage needs. It is equipped with fully redundant components for all major functions, such as RAID controllers, power supplies, fan modules, battery backup modules, and SAS JBOD expansion ports. The Hot-pluggable design is capable of providing uninterrupted services. In addition, the DSN-6000 Series incorporates advanced high availability features such as RAID 6 and RAID 60 support, writable snapshot, Microsoft Windows™ VSS support, and volume configuration restoration. These advanced features help to reduce or eliminate any system downtime. Unlike other vendors, D-Link’s DSN-6000 Series is able to upgrade to firmware without the system going offline. Both firmware image and volume handling are well protected by the redundant RAID controllers; when one RAID controller is down or has lost connection, the other RAID controller takes over its tasks immediately. This feature ensures that volumes and services are transferred seamlessly and simultaneously.

Applications
The optimised Input/Output Operations per second and unparalleled throughput are capable of providing run-time critical online services, such as Cloud storage, SQL, Exchange, and high-end surveillance storage. Furthermore, with its iSCSI interface, D-Link’s DSN-6000 Series is ideal for virtualisation environments – VMWare, Hyper-V, and Citrix. Multiple Operating Systems/Servers can be easily managed and protected by D-Link advanced data protection features, avoiding system downtime caused by single points of failure.

Expansion Options
The capacity of the DSN-6000 Series storage arrays can be easily expanded with the addition of the DSN-6020 Expansion Enclosure, which supports up to 12 SAS and SATA hard drives.  Up to 21 DSN-6020 enclosures can be mounted in a single or dual controller configuration storage array to expand the overall capacity to 1.5PB, and even higher capacity as larger hard drives are introduced.

Green Energy Savings
The DSN-6000 Series is equipped with D-Link Green features for saving power. A hard drive can be a very power-hungry component in a SAN. When properly configured, the power consumption of hard drives can be reduced to a minimum using the auto disk spin down feature. The DSN- 6000 Series systems monitor environmental temperatures to optimise the cooling mechanism. The fan modules respond only when needed. The power supply modules are all 80 PLUS power efficient, providing a more favorable power conversion rate. When combined, these power saving features help to greatly reduce energy consumption and increase the product’s lifespan.

Business Value-Added Features
The optimized IOPS and throughput enable the DSN-6210/6510 to provide runtime-critical online services, such as cloud storage, local and remote backup, SQL, Exchange and high-end surveillance storage. Furthermore, with the iSCSI interface, DSN-6210/6510 storage systems are ideal for virtualization environments such as VMWare, Hyper-V and Citrix.

SATA Bridge Board (DSN-654)
The DSN-654 SAS to SATA bridge board is designed to enable singleported SATA drives to connect seamleslly like native dual-ported SAS drives. The DSN-654 is required for each drive, for SATA deployments in a dual controller configuration as described in the diagram below. Also, these same rules will apply to SATA drives installed in any additional DSN-6020 expansion enclosures.
