Storage for Performance and Reliability The AssuredSAN® 4000 Series SAN storage arrays includes dual controllers, fans, power, and hot swappable drives as standard. Patented EcoStor™ batteryless cache backup eliminates the need for battery maintenance, boosting availability. These SAN storage systems are engineered to be able to demonstrate 99.999% availability and are compliant with NEBS Level 3 and MIL STD 810G requirements. 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™ Storage Operating System Enables Performance-enhancing SSD ConfigurationsRealStor software allows customers to implement next generation hybrid storage solutions that leverage the power of SSDs to increase storage performance. RealStor offers a range of options to boost performance no matter what your workload requirements. With RealStor 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 includes thin provisioning to make it easier to manage storage growth. Software Tuned for Performance Dot Hill''s firmware is optimized for 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 tuned to reliably deliver multiple streams through its Adaptive Read-ahead Algorithm.
