Adaptec 81605ZQ

Microsemi Adaptec's maxCache solution delivers an evolved application acceleration benefit with read caching solution and support for fully redundant SSD write caching. Series 8Q adapters can deliver up to 25x improvement in IOPS and 25x reduction in latency compared to HDD-only storage arrays.

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. By caching writes to a redundant SSD cache pool (RAID1, RAID1E or RAID5), maxCache 3.0 leverages the performance and latency capabilities of SSD technology for both read and write workloads.

Integration of maxCache 3.0 SSD caching technology is seamless. Adaptec Series 8Q adapters do not require changes to storage architectures, application software or operating systems.

Series 8Q adapters include our third-generation AFM-700 flash-based cache protection module to enable instant battery-free cache protection. Unique for the Adaptec 81605ZQ, flash backup is embedded on the board, eliminating the need for a daughterboard.

All of the "Q" adapters utilize our Zero-Maintenance Cache Protection (ZMCP), which provides full protection to cached data with no monitoring, maintenance, disposal, or replacement costs. ZMCP features 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.


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).

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.
