DSN-6420, Dual redundant controllers, 8GB Cache, SAS, SATAII, 4x 10Gbps, RAID, 2x 500W + 12x ST3000NC000
D-Link’s xStack storage systems are designed for small and medium businesses seeking a cost-effective solution. They present a high- availability iSCSI SAN platform that supports services for applications that require high throughput, scalability, and flexible storage planning. Both the DSN-6410 and -6420 storage systems can manage up to 60 hard drives in total - 12 in a RAID storage enclosure and up to 48 connected on JBOD units on the SAS expansion port.
The DSN-6410/6420 storage systems are specially designed for high-availability applications. Both DSN-6410/6420 are equipped with redundant components for major functions, such as dual MAC ports, dual power supplies, and dual fan modules. The DSN-6420 is also equipped with dual redundant RAID controllers, dual battery modules, and dual SAS JBOD expansion ports. The DSN - 6410 can be upgraded to the same capabilities as the DSN-6420 by adding the DSN-640 RAID controller module to it. With its hot-pluggable modules, the DSN-6410/6420 are capable of providing uninterrupted services. The firmware includes support for RAID 6, RAID 60, read-only or writable snapshots, Windows VSS, and volume configuration restoration. These advanced features help to reduce or eliminate any system downtime. Also, distinct from other systems in their class, you can upgrade the firmware of the DSN - 6410/6420 without going offline. The DSN-6420 ensures that firmware images and volume handling are protected by redundant RAID controllers. When one RAID controller is down or disconnected, the other RAID controller takes over its tasks immediately. The volumes and their related services are transferred seamlessly and simultaneously.
The DSN-6410/6420 systems have a maximum of 220,000 Input/Output Operations Per Second (IOPS) - higher than any other storage systems in their class. The total throughput is a maximum of 1300 MB/sec.
The optimized IOPS and throughput enable the DSN-6410/6420 systems to provide runtime-critical online services, such as cloud storage, SQL, Exchange, and high-end surveillance storage. Furthermore, with the iSCSI interface, DSN-6410/6420 storage systems are ideal for virtualization environments such as VMWare, Hyper-V, and Citrix. Users can install up to 32 OSes in the iSCSI system through the Boot-from-SAN feature. Using this feature, the multiple OSes/servers can be managed easily and protected by D-Link’s advanced data protection features. A single point of failure will not be able to cause any system downtime.
Green Energy Savings
DSN-6410/6420 storage systems are equipped with D-Link Green power-saving features. A hard drive can be the most power-hungry component in a SAN. When properly configured, the auto disk spin down feature can reduce the power consumption of hard drives to a minimum. DSN-6410/6420 storage systems monitor environmental temperatures to optimize 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.
