All-flash arrays (AFAs) address the demand for scaling storage performance to handle today’s intensive real-world data-access traffic; they belong to a new category of enterprise-storage systems comprised of flash memory, or solid-state drives (SSDs).
SSDs process tens of thousands of random I/O requests per second, far more than legacy hard disk drives (HDDs). SSDs are also more energy efficient, and latency is lower too. These advantages make AFAs the superior storage choice.
AccelStor’s FlexiRemap® technology is software that is based on the improving the fundamentals of flash memory. It was awarded Best-of-Show Technology Innovation at the Flash Memory Summit sow in 2016.
Our proprietary FlexiRemap® technology enables AFAs to meet data-access demands more efficiently than conventional storage arrays or Flash arrays running RAID schemas. FlexiRemap® is crucial in speeding up random-write access patterns, which are a major cause of storage bottlenecks. FlexiRemap® ensures that AccelStor storage devices meet the stringent performance demands of mission-critical applications.
FlexiRemap® technology adopts an efficient strategy to speed up data processing to accelerate random writes, which most real-world enterprise-data traffic has as a characteristic of operation and are one of the contributors of storage-access bottlenecks found in real world data center operations.
FlexiRemap® overcomes these challenges by rearranging new data into sequential block addresses before passing it to the SSDs. In this way, FlexiRemap® reduces the workload of SSDs by enabling them to directly write sequential data into consecutive pages.
We do not use NVRAM or any other elaborate staging schemas before we write data to the SSD. We write directly to the SSD from our DRAM and we do it only once while achieving impressive latency levels while we are at it.
This all results in our staggering performance levels and achieves the component durability only dreamt of in days gone by.
FlexiRemap® is a game changer in storage technology for All Flash Storage arrays and is empowering our goals of allowing our customers to realize Flash storage technologies at pricing levels equivalent to or lower than the spinning disk technologies of yesterday.
