LSI MegaRAID SAS 9271-4i Kit LSI00329 Dépliant

Product Brief

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 9271-4i, with four 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 9271-4i 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.

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 9271-4i 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.

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.

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.
