High-Speed Caching


Application performance degrades over time. Eliminate this problem with High-Speed Caching. High-Speed Caching is a proprietary caching algorithm that accelerates I/O by leveraging RAM as a read and write cache. DataCore supports up to 8 TBs of high-speed cache per node, creating a true ‘mega-cache’ to turbocharge application performance.

Read cache reduces requests to backend slower disk

Write caching accepts inbound data as fast as possible

RAM is a commodity component and therefore relatively inexpensive, yet it possesses outstanding performance characteristics and lacks the shortcomings that are attributed to Flash devices. RAM is an excellent technology to leverage for accelerating I/O performance and delivers a very high benefit-to-cost ratio across the entire storage architecture.

High-Speed Caching is critical for maintaining application performance since RAM is many orders of magnitude faster than the fastest Flash technologies and it resides as close to the CPU as possible. It is the fastest storage component in the architecture, delivering a 3-5x performance boost to applications and freeing up application servers to perform other tasks. It also extends the life of traditional storage components by minimizing the stress experienced from disk thrashing.


DataCore shattered the world record for price/performance in the Storage Performance Council’s prestigious SPC-1 Benchmark thanks in large part to the outstanding caching algorithms perfected over 18 years and the software’s unique parallel I/O architecture.
