Aberdeen iSCSI Host Scalable DAS Storage

  Aberdeen XDAS D-Series

3U 16Bay iSCSI 10GbE/SAS 6G DAS

The Aberdeen XDAS iSCSI RAID subsystem provides multiple GbE host interface ports that overcomes the limitations of parallel SCSI to achieve enhanced performance, high availability and reliability.

Using scalable DAS as a framework for building cost-effective iSCSI storage systems, the XDAS offers a complete scalable storage solution utilizing enterprise-class SAS drives, highly reliable or cost-effective SATA drives.

The Aberdeen XDAS iSCSI are the world's first iSCSI to SAS/SATA RAID arrays with up to six Gigabit Ethernet (GbE) ports on each controller. They help users achieve best-in-class performance while benefiting from the affordability and straightforward management of IP SANs.
Best-in-class performance can be acheived by combining multiple host channels into portal groups to increase the applicable bandwidth of each iSCSI session. 2, 3, or 4 GbE links can be grouped into TCP sessions so that bandwidth can be expanded for a server demanding higher throughput.

High Speed IP SAN with Powerful Scalability
Aberdeen furnishes all its XDAS D-Series iSCSI 10G-to-SAS/SATA models with two 10GbE iSCSI ports on each controller and a new SAS2.0 6G hard drive backplane. When data grows out of the capacity threshold of a single subsystem, you can scale it up to an installation housing more than one hundred drives through expansion enclosures. Powered by the new-generation RAID engine as its heart, the new D-Series iSCSI-to-SAS/SATA Series can deliver outstanding performance for processing large amounts of data. The no-delay, smooth operations it enables can satisfactorily meet the service levels your business requires. Coupled with the broad support for enterprise-level OS and server virtualization, it can serve as data storage for top-tier applications.

High-Availability SAN Delivers Great Price-Performance
Data availability is critical to any business operation. Aberdeen's XDAS D-Series storage solution features high-availability hardware designs with redundant, hot-swappable hardware components, such as RAID controllers, power supplies and cooling fans to eliminate single point of failure. Hardware RAID protection ensures data accessibility during drive failure. In the event of a power outage, CacheSafe technology will automatically leverage power of the Battery Backup Unit (BBU) to safeguard cached data by writing it to the flash module for permanent retention. To protect valuable data sets against more critical threats, the D-Series also supports local and remote replication capabilities. Data availability can be achieved with minimal downtime in case of human errors or data volume failure by employing D-Series replication features. Leveraging Infortrend's world class RAID engine and Fibre Channel protocol, XDAS D-Series storage solutions deliver breakthrough performance for demanding business applications. The models supporting Small Form Factor (SFF) drives can further increase performance density to support highly IO-intensive applications.

Flexible Scalability
The XDAS D-Series storage solution supports dynamic scaling to aid in the planning for future storage growth while satisfying the current storage needs. Flexible drive type and capacity support (2.5-inch or 3.5-inch, SAS or FC, and various drive sizes) satisfies current applications and enables you to accommodate future needs. D-Series storage solutions can be expanded to more than two hundred drives to meet the proliferation of storage growth. The “scale as you grow” flexibility of the D-Series storage solution minimizes the upfront investment and provides the best overall Total Cost of Acquisition (TCA).

Intuitive and Easy Management
Storage management should be simple. The XDAS D-Series storage solution includes a comprehensive management software suite, SANWatch, to centrally manage multiple D-Series subsystems over a standard TCP/IP network. Status and event information summary can be viewed on the portal window. Necessary functions to configure, manage and monitor the D-Series are only a few clicks away. Besides providing all firmware features through a user-friendly GUI, SANWatch also supports script-based configuration of multiple XDAS D-Series subsystems simultaneously. Automatic critical event notifications can be customized to suit the most critical storage environment. SANWatch will guide users through initializing, configuring and maintaining the EonStor DS every step of the way.

High Energy EfficiencyContributing to environmental sustainability, the XDAS D-Series storage solution enables energy cost-savings while maintaining performance. It is equipped with power saving designs such as high-efficiency power supplies, dynamic cooling mechanism and intelligent multi-level drive spin-down technology.
