Product Information

Using 4004 controllers, the Ultra Series storage arrays provide high-density SAN storage options for M&E, Telecommunications, Oil & Gas, HPC, Cloud Computing, and Big Data applications. Using high-performance SAS and SSD drives and ultra computing power to deliver 6.4 Gigabytes/second performance, these high-density SANs are ideal for IT managers who need to maximize storage performance and datacenter space.

Key Applications

Key SAN applications include: HPC, video post-production, media streaming, oil and gas apps, mobile datacenters, surveillance, telecom data capture, virtualization and other applications that require both performance and reliability.

Software for Optimizing Performance and Protecting Data

RealStor™ Software with Performance-enhancing SSD Configurations
RealStor 2.0 software allows customers to create the next generation hybrid storage solutions that leverage the power of SSDs to increase storage performance. RealStor 2.0 offers a range of options to boost performance no matter what your workload requirements. With RealStor 2.0 you can choose flash read-cache, RealTier for Flash - storage tiering with SSDs, or RealTier for Capacity - storage tiering between different speed HDDs to boost IO performance. In addition, RealStor 2.0 includes the rapid RAID rebuild feature and Thin Provisioning, along with virtual snapshots to enhance DR plans.

Software Tuned for Performance
Dot Hill's firmware is optimized for the randomized sequential I/O performance required in many demanding applications. Streaming high density and 4K video production is just one example where predictable high performance is required to deliver projects on time. Oil and Gas, and HPC applications also require storage that can sustain multiple streams of high-density data. Dot Hill's firmware is reliably tuned to deliver multiple streams through its Adaptive Read-ahead Algorithm.

Data Protection Software
Optional data protection software is available on the 4000 Series to fully protect your environment. Dot Hill offers optional AssuredCopy™, AssuredSnap™, and AssuredRemote™ DMS software to allow you to create point-in-time snapshots, volume copies, and replicate to a remote or backup site.

Supports Windows, Linux, Mac OS X
Microsoft certified. Citrix, Data Core, Veeam and VMware certifications pending.

Hardware - Performance and Architecture

The 4000 SAN storage arrays are powerful RAID data storage solutions which can scale to hundreds of terabytes of storage with additional expansion arrays. Our dual redundant design eliminates 'single points of failure' that can disrupt business operations. AssuredSAN arrays have dual active-active controllers for higher performance and failover, 'hot swappable' drives, dual power supplies and fans, all of which contribute to proven 99.999% uptime.
