MegaRAID® CacheCade® Pro 2.0
Read/Write Caching Software
Reduce Latency Bottlenecks for
Server-based HDD Volumes
Overview
Today’s workload-intensive business applications are often constrained
by the performance limitations of their existing hard disk drives (HDDs).
With this type of storage infrastructure already in place, it can be cost
prohibitive to switch to a new array based purely on solid-state drives
(SSDs). Although they are capable of many more transactions per second
than HDDs, SSDs have a very high cost per gigabyte and are not suited
for heavy, large file workloads. The key to accelerating the performance
of existing HDD arrays without making substantial investments in new
hardware is to deploy MegaRAID CacheCade software, which leverages
SSDs in front of HDD volumes to create high-capacity, high-performance
controller cache pools.
MegaRAID CacheCade Pro 2.0 read/write software eliminates the need
for manually configured hybrid arrays by intelligently and dynamically
managing frequently-accessed data and copying it from HDD volumes to
a higher performance layer of SSD cache (see Figure 1). Copying the most
accessed data (hot spot) to flash cache relieves the primary HDD array
from time-consuming transactions which allows for more efficient hard
disk operation, reduced latency, and accelerated read and write speeds.
This provides significant improvements to overall system performance,
two to twelve times that of HDD-only configurations, for a wide variety of
server applications including web, file, online transaction processing (OLTP)
database, data mining, and other transaction-intensive applications.

Key Features
• Accelerates performance of
existing HDD arrays with small
upfront investment
• Read and write caching of hot
spot data for significant reduction
in I/O latency
• Optimized for real-world
workloads of transaction-intensive
applications
• Uses less space and power
compared to adding short-stroked
drive spindles and unneeded
capacity
• More cost effective than using all
SSD storage volumes in storage
arrays
• Cached write data protected by
non-volatile CacheCade cache
pools (RAID 0, 1, 10) and data
availability protected by RAID
data redundancy
• Simple, intuitive management
tools to assign and manage
CacheCade SSD pool
• Industry’s first read and write
controller-based caching on
SSDs, dramatically enhancing
performance over the previous
generation CacheCade software

Product Brief
Cost-Effective Application Acceleration
CacheCade Pro 2.0 software offers the perfect combination of HDD capacity and SSD speed. CacheCade Pro 2.0
software is designed to improve the performance of a server’s existing drive volume(s) by, dynamically utilizing
SSDs as a dedicated pool of RAID controller cache to maximize random read and write performance.
Manual storage management and in-house application tuning costs can be avoided with CacheCade Pro 2.0
software, lowering the total cost of storage ownership for data centers and small-to-medium businesses.
Application Acceleration Across Business Critical Workloads
CacheCade Pro 2.0 software is the industry’s first software solution that offers both read and write controller-
based caching on SSDs, dramatically enhancing the performance gains achieved by the previous generation
CacheCade software. With the addition of write caching support, read/write-intensive workloads such as Exchange
server, high-performance computing (HPC) applications, Web 2.0, and other I/O-intensive OLTP database system
workloads experience dramatic performance improvements.
