- Eight-port 6Gb/s PCI Express 3.0 SATA+SAS RAID controller
- Second-generation 6Gb/s SATA+SAS controller, built on the LSISAS2208 dual-core ROC
- Proven interoperability with the latest server platforms based on the PCI Express 3.0 specification
The eight-port MegaRAID SAS 9271-8i, built on dual-core 6Gb/s MegaRAID SAS technology, provides a powerful combination of intelligent performance, enterprise RAID data protection and proven interoperability with the latest PCI Express 3.0 server platforms.
- 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 6 Gbps 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 9271-8i, with eight internal ports, delivers two 800 MHz PowerPC processor cores and a 72-bit DDRIII interface that drives 1 GB cache memory. Powered by the LSISAS2208 dual-core ROC, the 9271-8i controller includes the latest PCI Express 3.0 and 6 Gbps SAS technology and helps users to maximize the performance benefits of solid state storage.
- Protect cached data with LSI 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. To avoid the possibility of data loss or corruption during a power or server failure, LSI offers the CacheVault lash cache protection module or the LSIiBBU09 battery backup unit for the MegaRAID SAS 9271-8i controller. CacheVault lash 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 lash 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 lash 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.
