THE DATA CENTER CHALLENGE

Today’s data centers and cloud computing environments must provide
high I/O performance and low latency in order to support growing user
bases and large-scale applications such as web serving, file serving,
databases, online transaction processing (OLTP), Microsoft Exchange
Server, and high performance computing (HPC).

THE DATA CENTER CHALLENGE

 Tight budgets compel data
centers to increase the number of
users hosted per server in order
to reduce the cost of service
(COS) as well as the Capital
Expense (CapEx) and Operating
Expense (OpEx) of additional
hardware

 But adding more users to a
server causes an increase in
latency and a decrease in I/Os
per second (IOPS)

Users Hosted per Server


HOW CRUCIAL IS WEBSITE PERFORMANCE
TO BUSINESS?

 Akamai: 30%-50% of transactions that
take over 4 seconds, bail out1 Amazon:

 Shopzilla: 5-second speedup resulted in
25% pageview increase, 10% increase
in revenue, 50% decrease in
100ms
hardware, and a 120% increase in in Latency costs
traffic from Google1

 78% of site visitors have gone to a
competitor’s site due to poor
performance during peak times2
1%
in sales1
 88% are less likely to return to a site
after a poor user experience2

IMPACT OF LATENCY ON DATA CENTERS
AND CLOUD COMPUTING ENVIRONMENTS

 To maintain appropriate
performance levels, data centers
and cloud computing
environments must add new
servers to maintain appropriate
levels of service, even if the
existing servers have storage
capacity for more users

 This results in low storage
capacity utilization and an
increase in CapEx and OpEx
(namely maintenance, power and
cooling costs), as well as an
increase in physical space
requirements


ADAPTEC maxCache 3.0 SSD CACHING
SOLUTIONS – THIRD GENERATION

 Improving I/O performance while
also increasing the available
server capacity can increase the
number of users per server and
Cache
lower the cost per user

 Available on select Adaptec RAID
adapters, maxCache SSD
caching uses Solid State Drives Solid State SATA/SAS
(SSDs) and Hard Disk Drives Drives Hard Drives
(HDDs) to alleviate the bottleneck
that can occur between server
processors and hard
drives, delivering increased IOPS
and reduced latency


ADAPTEC maxCache SSD CACHING
SOLUTIONS

 Adaptec maxCache leverages its
unique presence in the data path
and utilizes an Adaptec-only
algorithm that identifies frequently-
accessed (“hot”) data, and
optimizes "reads" and "writes" by
copying this data into an SSD
cache pool for faster retrieval of
future requests.

 Because maxCache works at the
controller level, these processes
are completely transparent and do
not require any changes to
storage architectures, application
software or operating systems.


ADAPTEC maxCache 3.0 – READ AND
REDUNDANT WRITE BACK CACHING

 Introduced with 6GB/s Adaptec
Series 7Q RAID
adapters, maxCache 3.0 features
additional optimizations to the
algorithm that improve read
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

 Adaptec maxCache 3.0 supports
up to 8 SSDs with up to 2TB of
SSD cache READ MORE! Go to www.adaptec.com/maxcache

ADAPTEC maxCache 3.0 OPTIMIZED
DISK UTILIZATION

 Also new to maxCache 3.0 is the
inclusion of the Optimized Disk
Utilization (ODU) feature, which
allows the SSDs 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

 Eight 15k rpm SAS HDDs, 300GB capacity each; maxCache enabled with two 100GB SATA SSDs


LOWER TOTAL COST OF OWNERSHIP

 By accelerating IOPS and
reducing latency, maxCache
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 reduces
CapEx for server hardware
purchases

 The reduction in servers also
reduces OpEx by lowering
power, cooling, and maintenance *Using an estimated unit H/W cost of $15,000 and zero S/W license fees
**Using system Power Estimator @ 800W per server, and a National DOE average of
costs $0.11 per kWH
