Application Brief
Storage
The rapid expansion of high-performance
information processing and transmission
among millions of applications has fueled
the growth of the storage market. As well as
supporting a brisk growth rate, the storage
market is continually diversifying to serve
emerging markets. Market drivers include:
?  Rapidly increasing volumes of business 
data that need secure storage, including
email, web content, video and other
e-business material
?  Disaster recovery from power outages, 
fires and severe natural calamities
?  Government regulations, such as 
notification and retention policies
?  Explosive growth in sophisticated 
home information, communication and
entertainment systems

areas: SAN, NAS and digital media server.
These solutions range from high-performance
host processors to cost-optimized SoC
architectures with integrated redundant array
of independent drives (RAID), engines and
SATA interfaces.
Servicing enterprise and small/medium
business markets, SAN systems require
high-performance processors with high I/O
bandwidth and increased PCIe performance.
The host processor controls data movement
from the network to RAID ASICs, TCP/
IP or ISCSI protocol offload and provides
virtualization support and management
control. The P5 family of processors offer a
RAID 5/6 accelerator for use in SAN and NAS.
The RAID 5/6 accelerator performs the parity
calculation using a configurable Galois field
polynomial and supports a data integrity field,
making it ideal for use in high-performance,
high-reliability storage applications.
