 Why  use Redise Flash technology in Redise Pack

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.  Using Flash memory as an extension to RAM can deliver cost-efficiency, while Redis Enterprise Flash continues to deliver memory-like latencies and high throughput, even at large volumes.

The unique Redise Flash technology  in Redise Pack  slashes operational costs by over 80%,  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.

Redise Flash uses Flash as a RAM extension, rather than as persistent storage. The Redis internal dictionary, keys objects and ‘hot’ values are kept in RAM, while ‘cold’ values (which typically account for the larger part of the dataset) are kept in Flash. Multi- threaded and asynchronous Redis is used when accessing objects on Flash for optimal Flash performance. The product is based completely on the Redis core architecture and is compatible with all Redis clients, data types and commands.



Optimize costs of large transactional, operational and analytic processing, with Redise Flash’s ability to tune the RAM/Flash ratio for a configurable performance/cost profile.



Redise Flash performance varies by hardware and storage choices, and by the ratio of RAM : Flash. Typical throughput with sub-millisecond latencies:

A single SATA-based SSD instance in the cloud

100K ops/sec

A single NVMe-based SSD instance in the cloud

300K ops/sec

A single x86 bare metal server using Samsung or Intel NVMe Flash

> 1M ops/sec

A single Power8 bare metal server using IBM CAPI

> 1M ops/sec

When to use Redise Flash

Redise Flash is extremely suitable for use cases  where dataset sizes are >100 GB , values are larger than the keys and where “hot” objects account for 10-40% of all objects

Redise Flash characteristics and features are identical to those of standard Redise Pack. The product is available in both an x86/ 64-bit version which runs on all standard hardware (including cloud SSD instances) and a POWER version.
