Adaptec 71605Q PCI Express x8 3.0 6Gbit/s

PM8015 Processor, 16x SATA/SAS 6Gbps, 4x mini-SAS, PCI Express 3.0, 1024MB Cache, RAID 0/1/1E/5/6/10/50/60 The Adaptec Series 7Q SAS / SATA RAID adapters, with maxCache 3.0, deliver evolved application acceleration benefits with the industry-first read caching solution and support for fully redundant SSD write caching. Adaptec's 71605Q and 7805Q adapters can deliver up to 25x improvement in IOPS and 25x reduction in latency compared to HDD-only storage arrays.

<b>Adaptec maxCache 3.0 – The Evolution of Performance</b>
Adaptec maxCache 1.0 offered significant performance gains for read-intensive applications. By using SSDs to cache copies of frequently accessed (aka "hot") data, maxCache exploits the performance capabilities of SSDs to store/access read data from them rather than spinning media. The read caching function is further improved with maxCache 3.0, with additional optimizations to the learned-path algorithm.

Advancing the performance capabilities of SSD caching to a broader set of application workloads, maxCache 3.0 has evolved to support write caching. By caching writes to a redundant SSD cache pool (either RAID1E or RAID5), maxCache 3.0 leverages the performance and latency capabilities of SSD technology for both read and write workloads.

Also new to maxCache 3.0 is the inclusion of the Optimized Disk Utilization (ODU) feature. As SSD sizes continue to increase, monopolizing their entire capacity as a cache-pool is becoming less attractive. ODU allows the SSD to be partitioned into both a cache pool and logical device. The logical partition, unlike the cache pool, is exposed to the operating system, and can be used to install an OS to it or store other data that requires fast, low-latency access.

Integration of maxCache 3.0 SSD caching technology is seamless. Adaptec Series 7Q adapters do not require changes to storage architectures, application software or operating systems.

<b>Reduction of Capital and Operating Expenses</b>
With the acceleration of IOPS and reduction of latency, maxCache 3.0 allows data center and cloud computing environments to host more users and perform more transactions per second using less server hardware. The reduction in servers has a direct benefit on capital expenses for server hardware purchases, and additional financial benefit of reducing associated operating costs of power, cooling, and maintenance, delivering a highly reduced total cost of ownership (TCO) solution.

<b>Green Solution</b>
Series 7Q adapters include Zero-Maintenance Cache Protection, a revolutionary advancement that solves BBU deficiencies by providing full protection to cached data with no monitoring, maintenance, disposal, or replacement costs. ZMCP features 2GB of SLC based NAND flash memory with super capacitor technology. During a system power loss, the flash memory-based cache protection can preserve data for years.

<b>Advanced Data Protection</b>
Adaptec RAID Code (ARC) delivers maximum reliability with RAID levels 0, 1, 1E, 5, 6, 10, 50 and 60. ARC also offers RAID Level Migration (the ability to easily migrate RAID levels), Online Capacity Expansion (expand capacity without powering down the server), and Copyback Hot Spare (when a failed drive has been replaced, data is automatically copied from the hot spare back to the restored drive).

<b>Adaptec maxView Storage Manager</b>
Adaptec maxView Storage Manager provides the powerful features of Adaptec Storage Manager™ in an HTML5 web interface that can be viewed in standard desktop or mobile browsers without the need for separate software installation.
