™
3.0
Read and Write SSD Caching Solution
(Series 7Q SAS/SATA RAID Adapters 71605Q, 7805Q)
Improves Application Performance up to 25x and Reduces Latency by 25x
Product Highlights
6Gb/s throughput at each port
LP MD2 for 16 native SAS/SATA
ports (71605Q) and 8 native
SAS/SATA ports (7805Q)
Adaptec maxCache 3.0 SSD
caching support for read and fully
redundant write caching
— Allows conguration of SSD caching
pool in RAID0, RAID1, RAID1E and RAID 5
— Supports up to 8 SSDs with up to
2TB of SSD cache
Optimized disk utilization
— SSDs can be partitioned and some
of the capacity can be utilized as
separate logical drive to the host
(e.g. to boot the OS from)
Reduced capital & operating costs
— Support more users with less
hardware
— Improve quality of service with reduced
latency (25x) and accelerated IOPS
(up to 25x)
Preinstalled Adaptec Flash Module
700 (AFM-700) for Zero-Maintenance
Cache Protection with 2GB NAND ash
e Adaptec Series 7Q SAS/SATA RAID adapters,
with maxCache 3.0, deliver evolved application
acceleration benets with the industry-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 3.0 –
The Evolution of Performance
Adaptec maxCache 1.0 oered signicant
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.
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. 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 soware or operating systems.
Reduction of Capital
and Operating Expenses
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. e reduction in
servers has a direct benet on capital expenses
for server hardware purchases, and additional
nancial benet of reducing associated operating
costs of power, cooling, and maintenance,
delivering a highly reduced total cost of ownership
(TCO) solution.
Green Solution
Series 7Q adapters include Zero-Maintenance
Cache Protection, a revolutionary advancement
that solves BBU deciencies by providing full
protection to cached data with no monitoring,
maintenance, disposal, or replacement costs.
ZMCP features 2GB of SLC based NAND ash
memory with super capacitor technology. During
a system power loss, the ash memory-based
cache protection can preserve data for years.
Advanced Data Protection
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 oers 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
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
soware installation.
Compatibility, Reliability, and Support
Series 7Q supports all major operating systems,
including Windows, Linux, VMware and FreeBSD.
It has been extensively tested with third-party
components to deliver the utmost in compatibility.
e cards are backed by a three year warranty
and the company’s technical support.
