Th e Adaptec Series 7Q SAS/SATA RAID adapters, 

with maxCache 3.0, deliver evolved application 

acceleration benefi ts with the industry-fi rst 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. 

Adaptec maxCache 1.0 off ered signifi cant 

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.  

Th e 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.  Th e 

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 tech-

nology is seamless. Adaptec Series 7Q adapters 

do not require changes to storage architectures, 

application soft ware or operating systems. 

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. Th e reduction in 

servers has a direct benefi t on capital expenses 

for server hardware purchases, and additional 

fi nancial benefi t of reducing associated operating 

costs of power, cooling, and maintenance, 

delivering a highly reduced total cost of ownership 

(TCO) solution.

Series 7Q adapters include Zero-Maintenance 

Cache Protection, a revolutionary advancement 

that solves BBU defi ciencies by providing full 

protection to cached data with no monitoring, 

maintenance, disposal, or replacement costs.  

ZMCP features 2GB of SLC based NAND fl ash 

memory with super capacitor technology. During 

a system power loss, the fl ash 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 (71605E supports RAID 0, 1, 1E and 10). 

ARC also off ers 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 provides the powerful features 

of Adaptec StorageManager™ in an HTML5 web 

interface that can be viewed in standard desktop 

or mobile browsers without the need for separate 

soft ware installation.

Series 7Q supports all major operating systems, 

including Windows 8, Linux, VMware and 

FreeBSD. It has been extensively tested with 

third-party components to deliver the utmost in 

compatibility.  Th e cards are backed by a 3-year 

warranty and the company’s legendary technical 

support.
