The Adaptec 6805Q Unified Serial controllers with maxCache 2.0 delivers evolved application benefits with the addition of SSD write caching to the industry-first SSD read caching solution.  Offered on Adaptec’s 6Gb/s SAS hardware, the 6805Q can deliver up to 13x improvement in IOPs and 13x reduction in latency compared to hard-disk drive only storage arrays.  The significant performance gains enable data centers and cloud computing companies to host more users and perform more transactions per second with less servers, leading to quantifiable cost savings and quality of service (QoS) improvements.

Adaptec maxCache 2.0 Storage Controllers– Evolved Performance
First generation maxCache offered significant performance gains for read-intensive applications, delivering up to 11x performance improvement in 100% random read workloads.  Using SSDs to cache copies of frequently-accessed – or ‘hot’ – data, maxCache exploits the performance capabilities of SSDs to access the read data from the SSD rather than spinning media.  Read caching is improved with maxCache 2.0, with additional optimizations to the learned-path algorithm delivering an increase in overall IOPs performance to 13x for read-intensive environments. 

To deliver the advanced performance capabilities of SSD caching to a broader set of application workloads, maxCache 2.0 evolves to offer caching of write data as well.  By caching writes to the SSDs, maxCache 2.0 leverages the performance and latency capabilities of SSD technology for workloads with reads and writes.

Reduce Capital and Operating Costs by up to 70%
With the acceleration of IOPs and reduction of latency, maxCache 2.0 allows data center and cloud computing customers to host more users and perform more transactions per second using less server hardware.  Through the intelligent usage of SSD performance and HDD capacity, maxCache reduces capital expenses by reducing the overall server hardware investment necessary to support a given workload.  The reduction in servers has an additional financial benefit of reducing associated operating costs of power, cooling, and maintenance, delivering a highly reduced total cost of ownership (TCO) solution.

Green Solution
The 6805Q comes standard with Adaptec’s industry-first Zero Maintenance Cache Protection that eliminates Battery Backup Units ( BBUs) in favor of 4GB of NAND flash memory paired with a supercapacitor to protect cached data and eliminate the monitoring, maintenance, disposal and replacement costs associated with BBUs.

Reduce Energy Costs by Up to 70% with Intelligent Power Management
Adaptec cards with maxCache also include Adaptec Intelligent Power Management to slash power and cooling costs by spinning down idle disks and providing a lower power mode for active disks.

Compatibility, Reliability, and Support
The Adaptec 6805Q has been extensively tested with third-party components to deliver the utmost in compatibility. The cards are backed by a 3-year warranty and the company's legendary technical support.
