HSS Storage Compression Ratios

The MARS HSS (High Speed Storage) Object Storage format is specifically engineered to achieve exceptionally high data compression ratios for certain types of enterprise content, primarily text-based reports and print streams like IBM AFP and Adobe PDF.

Compression Mechanism & Benefits:

• High Efficiency: Documentation indicates compression rates ranging potentially from 200:1 up to potentially 400:1 compared to storing the original, fully composed reports or documents individually. This means data that might occupy hundreds of terabytes could potentially be stored in a single terabyte using the HSS format.
• Encoding & Resource Separation: This efficiency is achieved not through standard lossless compression algorithms alone, but by intelligently encoding the data and separating reusable resources (like fonts, overlays, or images used across multiple documents within a print stream) from the core document data. Resources are stored once and referenced by many documents within the storage object.
• On-the-Fly Composition: Instead of storing potentially millions of fully rendered, redundant report pages, HSS stores the core data and resources. When a user requests a specific document or page, it can be composed or rendered on-the-fly for viewing, drastically reducing the static storage footprint.
• Cost Reduction: The primary benefit of these high compression ratios is a significant reduction in physical storage requirements (disk space) and associated costs, including hardware, power, cooling, and data center floor space. This efficiency can be a key enabler for retiring expensive legacy storage infrastructure or reducing cloud storage expenditures.

This optimized storage approach makes HSS particularly suitable for long-term archiving of large-volume static report data where storage efficiency and cost reduction are paramount.
