Active Data Management

Active Data Management is the use of advanced algorithms to dynamically trace data IO in order to determine which data should be cached in server-tier flash. The IO for the most frequent read-write operations executes completely in the compute tier, reducing IO load on storage systems and increasing application performance.

Active Data Management takes a great number of variables into account, including:

Profiles: hardware & software

• The specific model SSD being used
• The server volumes the SSD will accelerate
• The server operating system, VMs & applications

Parameters: configurable & auto-tunable

• Hot data identification: read-ahead & read-around methods
• Disk parameters: write-back, write-through, read-only
• Performance management – data flushing and queuing

Algorithms: continuously monitor IO & tune caching

• Write stream recognition
• Alignment of data with SSD block structure
• Performance and efficiency management

Reports: cache performance & SSD status

• Analysis of SSD cache performance
• Trouble reporting and predictive analytics
• Exceptional IO behavior versus profile
