DSN-5000 Series iSCSI SAN Array High Availability (HA) • DSN-510 - Four 1GbE Ports (Secondary controller for DSN-5110-10) • DSN-520 - Eight 1GbE Ports (Secondary controller for DSN-5210-10) • DSN-540 - One 10GbE Port (Secondary controller for DSN-5410-10) Drive Expansion • DSN-5000-10 Expansion Array • For use with DSN-5110-10, DSN-5210-10 and DSN-5410-10 Primary SAN Arrays • Provides 12 Hot-Swap Drive Bays • Up to six expansion arrays supported for 84 drives total (DSN-5210-10 and DSN-541) business xStack Storage® HA capable 4x1GbE, 8x1GbE or 1x10GbE iSCSI SAN Array with 12 SAS/SATA1 Bays (expandable to 84 bays) that offer a "discrete implementation" where in various components are selected separately, then assembled. RAID support D-Link's xStack iSCSI SAN arrays support RAID levels 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 scan, and nondestructive data migration to prevent disk failure. Embedded Centralized Storage Management All of the D-Link xStack Storage products share a common easy-to-use configuration and management GUI console that allows you to manage multiple units from a single screen. The intuitive wizards ensure you will have your SAN out of the box and ready to go in a few minutes. 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 Features The DSN-5000 series also provides an advanced set of features for efficient management and optimal storage performance. in an application-dependent manner. Volatile cache data protection is afforded via an on-board battery supporting 2GB of cache memory for a minimum of 72 hours. A write-back or write-through cache memory policy can be selected manually or automatically, depending on the status of the battery's charge. The DSN-5000 series supports jumbo frames and VLAN tagging to segregate traffic into isolated zones for secure access, improving network throughput and reducing CPU overhead. D-Link's volume virtualization technology utilizes the concept of storage extents, which are the fundamental building blocks used to enable features such as RAID, online capacity expansion, volume reconfiguration and migration. Each disk drive can contain multiple and divergent RAID configurations instead of requiring dedication to a single RAID set. This technology allows for the support of mixed disk drive capacities for volume creation. Volume capacity expansion and RAID level migration are performed online with minimal impact to users. Additionally, volume growth can occur without volume migration or reconstruction. Users can quickly deploy a SAN and simply add more drives as needed. 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 replacement of Direct Attached Storage (DAS), providing primary online storage, or providing up to 1160 MB/s bandwidth for security surveillance, video editing, video post-production applications, the DSN-5000 series will provide the performance and functionality needed. For the fastest RAID performance offered in the industry, D-Link's adaptive cache management provides write coalescing and multi-stream read-ahead on a volume basis, optimizing cache utilization and performance
