LSI 9265 MegaRAID Cachecade Supplementary Review: Nuts and Bolts

One can improve the performance of small files by up to 50X which for certain types of setups can reap HUGE results. Webservers, File Servers, and OLTP (Online Transaction Processing) will benefit tremendously. There is definitely a large group of users that would be very interested in combining the positive aspects of both solutions (HDD/SSD) into one cohesive unit.  How …

LSI 9265 MegaRAID Cachecade Supplementary Review: MLC vs SLC

CacheCade performance is much more dependent on SSD read performance than on SSD write performance, so the performance depends upon the size of the SSDs and the total size of the data hot spots. If there simply aren’t many hot spots on the array being accelerated, you will not gain as large of a performance gain. Once again, in our …

LSI 9265 MegaRAID Cachecade Supplementary Review: Hot-Warm-Cool-Cold

Zoned Setup- A more complex read pattern that is much more demanding of the caching algorithm. The overlapped cold-cool-warm-hot data regions IOMeter benchmark is the most stressful on the hot data caching algorithms and so results typically reach performance in the 30,000 to 45,000 IOPS range. The base array in this scenario is generating around 500 IOPS before acceleration, which …
