ScaleFlux, Inc. has added new features in its CSS 1000 product line: Atomic Write and Namespace Streams. /These features are available to existing customers (via a downloadable package) and to new customers. Both Atomic Write and Namespace Streams enable performance and endurance benefits for data-intensive workloads.

Atomic write (AW) is the ability to guarantee a single write of blocks up to 1MB in size. For database applications, this assures each Database record update is written in its entirety in a single transaction rather than breaking up the write into multiple transactions. This bypasses the traditionally used Double Write Buffer and increases drive endurance as a result of reducing total write operations. AW preserves existing benefits such as recovering data in the event of a crash and increases transactions per second for write-intensive workloads.

Namespace Streams (NS) greatly improves Flash storage I/O performance, latency and endurance by minimizing unnecessary garbage collection. NS allows customers to create separate Streams of logically-associated data with different life cycles by simply associating each Stream with a Namespace. For example, log updates, files, and transaction records could each be a Stream. CSS then places the data from a given Stream together on physically- associated region of Flash, each with its own set of garbage collection units and its own tunable overprovisioning. This yields lower overall latency and write amplification.
