The ESDS B24F-R2652 is a small-form-factor hybrid model combining the groundbreaking performance of 16G Fibre Channel (FC) with iSCSI ports. Featuring enterprise-class protection and scalable to use up to 240 2.5” drives, the dual-controller ESDS B24F-R2652 provides optimal performance density combined with the high performance necessary for meeting the demands of both present & future IT challenges.

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, up to 16G connectivity, easy and intuitive management and exceptional price-performance, EonStor DS provides a decisive competitive edge by making IT efficiency keep up with growing needs.

High-Availability SAN
Data availability is critical to any business operation. EonStor DS 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. The models supporting Small Form Factor (SFF) drives can increase performance density to support I/O-intensive applicaitons.

Flexible Scalability and High Density
The EonStor DS storage solution supports dynamic scaling. 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. EonStor DS storage solution can be expanded to more than two hundred drives to meet the proliferation of storage growth. The “scale as you grow” flexibility of the EonStor DS storage solution minimizes upfront investments and provides the best overall Total Cost of Acquisition (TCA). In addition,4U/48-bay solutions offer high storage density to meet extreme capacity requirements while excellent cost efficiency.

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 EonStore 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 sustain-ability, EonStor DS 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.

Superior Performance Levels
EonStor DS G7i systems offer superior performance levels that are ideal for mission-critical applications such as HD media editing and broadcasting, cloud services, and HPC. Featuring advanced hardware platforms and up to 16G FC connectivity, EonStor DS G7i systems provide superior throughput of up to 5,500 MB/s Read and up to 3,900 MB/s Write and support up to 1.2M IOPS.
