Featuring 1Gb/s iSCSI host connectivity and 6Gb/s SAS drive support, the ESDS S12E-R2140 provides a budget-friendly choice to help SMB users easily deploy high-availability IP SANs. Accommodating 12 SAS or SATA drives, the dual-controller ESDS S12E-R2140 delivers optimal performance. The enterprise-class data protection and outstanding price-performance of the ESDS S12E-R2140 can generate significant business advantages.

Downtime can have serious consequences for enterprises and SMBs. The challenge for SMBs is to pro-actively prevent downtime within a limited budget. With today's price points in mind, the EonStor DS storage solution provides comprehensive data protection to ensure the highest data availability for the storage area network (SAN) and direct attached storage (DAS). Coupled with advanced hardware design, modular architecture, easy and intuitive management and exceptional price-performance, EonStor DS brings price-conscious companies a decisive competitive edge by making IT efficiency keep up with growing storage needs. In addition, EonStor DS G7i offers superior performance levels to help companies meet demand of mission-critical applications.

High-Availability SAN Delivers Great Price-Performance

Data availability is critical to any business operation. Infortrend’s EonStor DS 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, EonStor DS 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 the EonStor DS replication features. Leveraging Infortrend's world class RAID engine, the EonStor DS storage solution delivers 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 EonStor DS 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 SATA, and various drive sizes) satisfies current applications and enables you to accommodate future needs. EonStor DS storage solution can be expanded to up to 144 drives to meet the proliferation of storage growth. The “scale as you grow” flexibility of the EonStor DS storage solution minimizes upfront investment and provides the best overall Total Cost of Acquisition (TCA).

Intuitive and Easy Management

Storage management should be simple. The EonStor DS storage solution includes a comprehensive management software suite, SANWatch, to centrally manage multiple EonStor DS subsystems over a standard TCP/IP network. EonStor DS status and event information summary can be viewed on the portal window. Necessary functions to configure, manage and monitor the EonStor DS are only a few clicks away. Besides providing all firmware features through a user-friendly GUI, SANWatch also supports script-based configuration of multiple EonStor DS 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 Efficiency

Contributing to environmental sustainability, the EonStor DS storage solution enables energy cost-savings while maintaining performance. It is equipped with power savings designs such a high-effiency power supplies, dynamic cooling mechanism and intelligent multi-level drive spin-down technology.
