Redis on Flash

Big Data Meets Real-time

Redis on Flash technology enhances Redis to run on a combination of RAM and more cost-effective Flash memory. For datasets larger than 1 TB, this is the most cost-optimal way to run Redis with the same sub-millisecond latencies and extremely high throughput. Redis on Flash includes the characteristic Redis Enterprise stable high performance, zero downtime linear scaling and hassle-free true high availability.

Why Redis on Flash?

For Redis use cases such as real-time analytics, time-series data analysis, search, machine learning and more, dataset sizes can become voluminous and the cost of memory can become prohibitive. The unique Redis on Flash technology slashes infrastructure costs by using SSDs as an extension of memory. With its breakthrough  approach of tiering access to data, with keys and hot values in RAM, while cold values are stored on Flash, this technology delivers the blazing fast sub-millisecond latencies and high throughput of Redis, with a lower cost infrastructure.
