Unmatched RAID Performance for Next-Generation Servers and Storage

Todays 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.

MegaRAID SAS 9271-4i

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 benefits of solid-state storage.

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 9271-4i 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.

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 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. 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.
