This is an AssuredSAN 4004 6GJBOD 2JM AC DH Drive-less System with Rail Kit.
Dot Hill AssuredSAN 4004 storage arrays offer greater data security, faster throughput and substantial
business benefits for markets that demand extremely high-bandwidth performance, such as cloud service
providers, media & entertainment, oil & gas, telecommunications, big data analytics and digital image
archiving. Host interface options include 12Gb SAS, 8Gb and 16Gb FC, 1Gb and 10Gb iSCSI and the only
hybrid 16Gb Gen 5 Fibre Channel/10Gb iSCSI converged interface.
The AssuredSAN 4004 solutions are built on the company's ninth-generation RAID stack, which delivers up to
100,000 input/output operations per second (IOPS) from disk, sustained sequential read performance of up to
6400 MB/second and writes of up to 5300 MB/second. The Dot Hill RAID Companion Processor (RCP) allows
4004 solutions to deliver dramatic performance gains at very aggressive price points. AssuredSAN 4004
solutions also integrate all the performance tuning and optimizations of the previous-generation AssuredSAN
4000 models, which includes streaming performance optimization to handle randomized, sequential workloads.
Dot Hill's latest firmware utilizes a proprietary Adaptive Read-ahead Algorithm that analyzes workloads and
fine tunes options to optimize the performance of specific kinds of demanding workloads, delivering better
response times and meeting IT service level agreements
