Breaking the Disk Barrier with In-Memory DBMS Technology: Sybase Adds a Big Performance Boost for ASE 15.5
Over the course of the past 10 years, in-memory database technology has emerged as a key means of boosting performance and scalability and containing storage costs. This technology has evolved from use only for caching, or for extremely high-speed data systems, to much more mainstream IT applications. In-memory DBMS (IMDB) usage is now applied in ways that deliver better performance and respond flexibly to increased user demand at low incremental cost. The reason for this is that the economics of computing have shifted in favor of this approach due to the following factors:
- Cheaper, faster processors in multicore, multiprocessor configurations
- 64-bit memory addressability combined with cheaper memory that makes large in-memory deployment affordable
- Newer DBMS internal data management software that better exploits memory
This white paper discusses the growing need for high-performance database management, without disrupting applications and the operations of the datacenter. It reviews the ways in which in-memory DBMS technology has emerged and been developed to satisfy this need. It discusses issues of performance versus durability and how an in-memory database strategy can be used to provide better high-speed, high-volume data management without sacrificing data integrity. The document then explores how ASE 15.5 with its in-memory databases capability provides a means of meeting these challenges while operating in a manner that is familiar to Sybase ASE users and fully compatible with existing ASE applications and installations.
