High density dual controller 2U 24-bay compact storage systems designed for 2.5” drives and purpose-built to handle intense data throughput loads. It is capable of up to 11,000MB/s read and 5,500MB/s write. EonStor DS 4024STB Gen2 has a unique dual host board design that expands hybrid interconnectivity possibilities for a more diverse storage network, and fully integrates 12Gb/s SAS technology both host-side and drive-side for high speed data transfer.

EonStor DS 4000 systems deliver top-notch performance in their segment, bringing unrivaled power to SMBs. With their unique dual host board design and 12Gb/s SAS interfaces to internal SAS or SATA disk drives, these systems achieve a massive throughput to meet even highly demanding applications such as media editing. They are also extremely scalable and integrate advanced data services such as SSD Cache, automated storage tiering, and self-encrypting drives.

Massive performance makes EonStor DS 4000 systems perfect for media industry

Thanks to optimized design and advanced processing power, EonStor DS 4000 systems achieve unprecedented performance figures for mid-range storage and can easily handle even very intense networked storage demands. Delivering up to 600K end-to-end IOPS, 11,000MB/s sequential read throughput and 5,500MB/s sequential write throughput, they ensure users are prepared to take on IT challenges for years to come.

Leading performance turns EonStor DS 4000 systems into productivity-boosting hubs for multiple 2K resolutions and 4K resolutions streams in media industry, with no slowdown or lag experienced thanks to their ample processing power and storage bandwidth. Strong performance means smooth service to large workforces.

Fully optimized for SSD

The storage industry is moving towards high speed, reliable, and efficient solid state drives, and the EonStor DS 4000 series is future-ready. In addition to hybrid drive trays (2.5”/3.5”), it supports a range of SSD-focused software solutions, including automated storage tiering and self-managing SSD Cache. These two functions combine to leverage the advantages of each drive type, whether SSD, SAS, NL-SAS or SATA, by sorting data based on tenure and access frequency. This allows hot data to enjoy 16X more read IOPS and 88% lower latency, while maximizing SSD utilization and protecting your investment. EonStor DS systems feature real time wear level monitoring to pre-empt potential failures and prevent data loss.

Native support for 12Gb/s SAS: host and drive side

The 12Gb/s SAS host and drive side interface offers a low latency pathway without compromising performance due to delays or bandwidth limits. It features built-in connection scaling, adapting to different capacities and adjusting actual connection bandwidth based on real time loads. With 12Gb/s SAS, users benefit from a better costperformance ratio, improving their ROI.

EonStor DS 4000 systems feature dual host board controller

Innovative design places two host boards side by side on EonStor DS 4000 systems, unlocking higher levels of flexibility and performance by allowing different combinations of Fibre Channel (up to 16Gb/s), SAS (up to 12Gb/s), iSCSI (up to 10Gb/s), FCoE (up to 10Gb/s). Each host board can also support hybrid interfaces, effectively quadrupling connectivity.

Emergency backup power safeguards data

Protecting against data loss due to prolonged power outages, EonStor DS 4000 systems include super capacitors paired with a flash module. If power fails, data is written to the flash cache and kept powered by the super capacitors for extended periods of time. Super capacitors require no maintenance and last for the life of the storage system, making them a very convenient and cost effective emergency backup measure.

Comprehensive data and security services

All EonStor DS 4000 systems support self-encrypting drives (SEDs), which are factory secured against even the most direct physical intrusion. SEDs defend against data theft and misplacement and make deletion much faster than traditional methods, as invalidating the key renders all data on the drive permanently unreadable.

For disaster recovery, the EonStor DS family supports secure remote replication. Local replication is offered via snapshot and volume copy/mirror. Thin provisioning is standard, and all data is covered by smart media scan and IDR (Intelligent Drive Recovery) technology, which detects faulty sectors and quickly clones affected data to prevent loss, even due to silent errors that would go unnoticed by other storage systems. All of these features are easily accessible from our user-friendly SANWatch browser-based interface.
