SSD caching uses Solid State Drives (SSDs) and Hard Disk Drives (HDDs) to alleviate the bottleneck that can
occur between server processors and hard drives by intelligently routing data to the performance-optimized location.

Adaptec maxCache™ SSD Caching Solutions
How maxCache 2.0 Works:
Adaptec maxCache 2.0 SSD Caching leverages a Learned Path Algorithm that identifies frequentlyaccessed data and optimizes reads and writes by moving a copy of this data directly into an SSD cache
for faster retrieval of future requests.
By leveraging its unique presence in the data path to create a “cache pool” of “hot” data, maxCache 2.0
SSD caching can provide significant performance gains compared to HDD-only deployments.
Adaptec maxCache solutions are application-agnostic and do not require changes to storage architectures, application software or operating systems.

Glossary
Capital Expenses: Money spent by a company to purchase physical assets, such
as IT equipment.
“Cold” data: Data which is accessed infrequently or written continuously. Cold
data is typically less timely than “hot” data, such as week-old emails.
Flash memory: A type of solid state (no moving parts) memory that can be
erased and reprogrammed. It is mainly used in memory cards and USB thumb
drives for general storage. Flash memory is non-volatile, which means it can retain
stored information even when not being powered.
Hard Disk Drive (HDD): A motorized mechanical device that stores data on rotating
magnetic platters. HDDs are typically slower than flash memory.

Applications
Adaptec maxCache 2.0 delivers performance benefits for both read and write operations.
“Hot” data: Data which is accessed frequently, such as recent emails or popular
products on an e-commerce site. Adaptec Cache Solutions store copies of “hot”
data blocks on SSD cache for fast retrieval.
I/O: Input/Output. Any operation that moves information from a disk or another
device to a computer.
IOPs: Input/Output operations per second.
Latency: The delay in performance that occurs when sending a packet of data
from one designated point to another.
Operating Expenses: An ongoing cost for running a business, or system. IT-related
operating expenses include the costs of employees to monitor and maintain
systems, as well as energy costs.
Grow Your Business with Adaptec
Adaptec maxCache 2.0 helps you sell into Data center and cloud computing environments
with high “read” demands, such as web serving, file serving, and databases, as well as I/Ointensive environments with mixed workloads, including OLTP, Microsoft Exchange Server,
and High-Performance Computing.
Solid State Drive (SSD): A data storage device that uses non-moving flash
memory instead of the rotating platters of a hard disk drive to store data. SSDs
typically outperform HDDs.
