Highest Server RAID Performance for Database and Multimedia Applications
As storage demands expand and processing loads grow, it becomes increasingly more difficult
for administrators to achieve maximum performance from their applications. The newest line
of MegaRAID^® 6Gb/s SATA+SAS controller cards, built on the LSI SAS 2208 dual-core ROC, offer
unmatched I/O performance for database applications and streaming digital media environments.
The MegaRAID SAS 9266-4i controller, with four internal ports, delivers two 800MHz PowerPC
processor cores and a 72-bit DDRIII interface that drives 1GB cache memory. Users can deploy
the MegaRAID SAS 9266-4i controller in existing HDD-based server environments for significant
performance gains. Alternatively, for users implementing server platforms based on solid-state
storage, these next-generation MegaRAID controllers exploit the potential of SSDs for unsurpassed
performance and enterprise-class reliability.
Protect Cached Data with 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, Avago offers the CacheVault flash cache protection module or the LSIiBBU09 battery
backup unit for the MegaRAID SAS 9266-4i 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 to flash 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 and the system goes on without loss of data.
Customers have the flexibility to choose a traditional LiON battery solution or a greener, lower 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 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^® 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^™ of software provides essential tools to manage MegaRAID
products, whether deployed in an enterprise or small business. Avago 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.
