What is Plexistor Software Defined Memory (SDM)

Plexistor Software Defined Memory (SDM) platform converge memory and storage, to deliver near-memory speed with the persistency and capacity of traditional storage. SDM is ideal for in-memory applications to meet the demand for today’s increased data loads. This architecture decouples the management and allocation of storage from the data access path, enabling the application to access memory as if it was storage and storage as if it was memory.

SDM Taking MongoDB to the Next Level

SDM unlocks and delivers huge benefits by eliminating the I/O bottlenecks architecturally endemic to traditional storage software, such as redundant software caching in main memory and redundant block representation at multiple points across the operating system. MongoDB users had to sacrifice performance for the safety of the data being written to storage. Through the revolutionary approach of Plexistor’s SDM, MongoDB performance no longer must be sacrificed to ensure data persistence or durability. As a result, database administrators can eliminate the risk of losing non-persistent data, and application users no longer have to accept “tolerable data loss” for performance.

The test results bellow demonstrate unequivocally that Plexistor’s SDM makes it possible for MongoDB to achieve maximal durability while achieving 450% performance increase.
