As with all Dot Hill AssuredSAN storage systems, the AssuredSAN 4000 Series features energy-saving drive spin-down and patented technologies such as Dot Hill's SimulCache™ and EcoStor™ to help customers meet a growing set of environmental concerns. Dot Hill's EcoStor battery-free alternative for cache memory leverages a combination of super capacitors and flash memory that outlasts traditional batteries nearly fivefold. Benefits include lower maintenance and disposal costs and reduced server and application down-time due to scheduled battery replacement and maintenance.Dot Hill's SimulCache technology leverages redundant RAID controllers, thus eliminating the performance degradation associated with conventional cache mirroring. The implementation of a high-speed dedicated PCI-Express bus streamlines write performance resulting in superior overall system responsiveness, driving faster application throughput. Dual-redundant RAID controllers, dual power supplies and dual fans bring uptime figures to 99.999 percent availability, so customers don't experience downtime or data loss.
