Unmatched RAID Performance for Next-Generation Servers and Storage 
Today’s data center, cloud and high-performance computing environments not only require increased 
storage capacity to handle massive volumes of data, but are also challenged to protect and deliver data 
as quickly as possible to meet the needs of applications and end users. To address these performance 
demands as capacity scales, the newest 6Gb/s SAS RAID controllers from LSI offer a powerful combination 
of intelligent performance, enterprise RAID data protection and proven interoperability with the latest 
server platforms based on the PCI Express 3.0 specification. The MegaRAID SAS 9271-8i, with eight internal 
ports, delivers two 800MHz PowerPC® processor cores and a 72-bit DDRIII interface that drives 1GB cache 
memory. Powered by the LSISAS2208 dual-core ROC, the 9271-8i controller includes the latest PCI Express 
3.0 and 6Gb/s SAS technology and helps users to maximize the performance benefits of solid state storage.
Protect Cached Data with LSI MegaRAID CacheVault™
 Technology or BBU
RAID caching is a cost-effective way to improve I/O performance by writing data to a controllers’ cache 
before it is written to disk. In write-back mode, data written to cache is vulnerable until it is made 
permanent on disk. To avoid the possibility of data loss or corruption during a power or server failure, 
LSI offers the CacheVault flash cache protection module or the LSIiBBU09 battery backup unit for the 
MegaRAID SAS 9271-8i controller. CacheVault flash cache protection uses NAND flash memory powered 
by a super-capacitor to help protect data stored in the MegaRAID controller cache. The RAID controller 
automatically writes the data in cache memory to flash storage when a power failure occurs, while the 
super-capacitor keeps the current going during the process. When the power comes back, the DRAM is 
recovered from flash storage and the system goes on without loss of data. Customers have the flexibility 
to choose a traditional LiON battery solution or a greener, lower total cost of ownership (TCO) cache 
protection solution with MegaRAID CacheVault technology.
Support for Advanced Software Options 
The LSI family of 6Gb/s MegaRAID controllers are designed to support advanced software options that 
provide white box channel partners with enhanced performance and data protec¬tion capabilities. These 
new software options help enable end users to address key business challenges while helping to deliver 
a higher return on their IT investments. MegaRAID CacheCade™ Pro 2.0 software and MegaRAID Fast Path 
software boost transactional I/O performance of solid state disk configurations, while MegaRAID Recovery 
software and MegaRAID SafeStore™ software enable enhanced data protection and security. 
Intuitive RAID Management Utility 
The MegaRAID Management Suite™ software provides essential tools to manage MegaRAID products, 
whether deployed in an enterprise or small business. LSI offers a collection of applications and tools 
including a pre-boot setup utility and a full spectrum of online RAID management utilities. This suite of 
applications allows administrators to adjust SAS or SATA topology views from the system host, controller 
and disk enclosure down to the logical and physical drive level. Extending to enterprise deployments, 
these tools scale to more easily configure, monitor and manage RAID and JBOD volumes locally or over the 
LAN network.
