Lsi Megaraid SAS 9266-8i - Storage Controller (raid) - 8 Channel - Sata-600 / SAS 2.0 Low Profile -

Inleiding

As storage demands expand and processing loads grow,it becomes increasingly more difficult for administrators to achieve maximum performance from their applications. The MegaRAID SAS 9266-8i controller,with eight internal ports,delivers two 800 MHz PowerPC processor cores and a 72-bit DDRIII interface that drives 1 GB cache memory. Users can deploy the MegaRAID SAS 9266-8i 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 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. 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,LSI offers the CacheVault flash cache protection module for the MegaRAID SAS 9266-8i 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.
