Product Brief
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 Avago
oer 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 specication.
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 LSI SAS 2208 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 benets of solid state storage.
Protect Cached Data with MegaRAID CacheVault™ Technology or BBU
RAID caching is a cost-eective 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, Avago oers the CacheVault ash cache protection module or the LSIiBBU09 battery
backup unit for the MegaRAID SAS 9271-4i controller. CacheVault ash cache protection uses
NAND ash 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 ash 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 ash storage and the system goes on
without loss of data. Customers have the exibility 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 family of 6Gb/s MegaRAID controllers are designed to support advanced software options that
provide white box channel partners with enhanced performance and data protection 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 congurations,
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. Avago oers 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 congure, monitor and
manage RAID and JBOD volumes locally or over the LAN network.
