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 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 9271-8iCC,
with eight 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 9271-8iCC 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.
MegaRAID^® CacheCade^™ Pro 2.0 and MegaRAID Fast Path Ready
The “CC” family of 6Gb/s MegaRAID controllers ship as standard with CacheCade Pro 2.0 and Fast Path
software enabled out of the box. These software offerings help to optimize application performance in
direct-attached storage environments configured with solid-state drives (SSDs). CacheCade Pro 2.0 read/
write software is designed to dramatically accelerate application I/O performance of hard disk drive
(HDD)-based arrays by intelligently caching frequently accessed, or “hot spot”, data to SSDs. Using SSDs as
a dedicated pool of high-performance cache memory in front of HDDs can cost-effectively improve both
read and write performance, reduce I/O latencies, accelerate application response time and lower RAID
access and rebuild times. MegaRAID Fast Path software is a high-performance I/O accelerator, designed
to dramatically boost transactional application throughput of SSD arrays connected to the MegaRAID
controller card.
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 9271-8iCC 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.
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 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.
