The LSI MegaRAID CacheCade software pack leverages SSDs in front of HDD volumes to create high-capacity, high-performance controller cache pools. Compatible with MegaRAID SAS 9265/9266/9270/9271/9285/9286 series controller cards.
Improve application I/O performance
Interest in solid-state storage has grown rapidly; however, the biggest issue holding back solid-state storage in general purpose servers today is that enterprise class drives cost at least 10 times as much as conventional hard drives from a price-per-GB perspective. Capitalizing on the performance advantages of solid state drives (SSDs) as well as the cost and capacity advantage of SATA and SAS drives, CacheCade software is designed to allow a server's existing drive volume to utilize SSD technology as a secondary tier of cache to maximize random read performance. SAS drives can sustain only a few hundred IOPS while SATA drives reach even less. SSD devices, on the other hand, are capable of delivering IOs per second in the tens of thousands. CacheCade software allows for frequently- read data (hot-spot) to be moved to second tier SSD cache for much faster retrieval of that data when it is time for it to be re-read. This provides significant performance improvement of 2x to 50x for read-intensive applications such as web, file, SQL, and other transactional server applications.
Cost optimized SSD usageProduct Highlights
MegaRAID CacheCade software allows customers to blend inexpensive SATA hard disk drives (HDDs) with a small amount of solid state storage capacity to provide a substantial performance boost while avoiding complete 1:1 replacement of SATA HDDs with faster SAS HDDs, adding additional SATA HDDs or moving to an all SSD RAID volume to achieve performance requirements. This combination of HDDs and SSDs as secondary cache helps improve IOPs per dollar, particularly in random read intensive applications. Simply select an SSD(s) and associate it with one or more virtual drives to configure and use CacheCade software.
- Dynamic Read and Write caching of hot spot data for significant reduction in I/O latency
- Accelerates I/O performance of existing HDD arrays using SSDs as high-performance cache
- Optimized for real-world workloads of transaction-intensive applications
