The idea of storage tiering is mainly based on the implementation of an optimized storage infrastructure, where different storage technologies are combined according to their advantages and specific properties. The optimization is carried out in view of performance, capacity and costs.
The Tiered Storage Concept exists of a two dimensional, multi-tier storage hierarchy, in which data can be migrated from one tier to another as well as within one tier.
The Tiered Storage Architecture consists of three storage tiers: Performance, Capacity and Archive Tier.
Pre-defined properties are assigned to each tier. Whereas the Performance Tier consists of high performance storage, the Capacity Tier offers high capacity and provides permanent access to the stored data. The Archive Tier is designed for long-term archiving and offers additional capabilities necessary for compliant archiving.
Inactive data, which often represent up to 80% of the total data volume, can be migrated by means of storage tiering via pre-defined policies to another storage layer. Therefore expensive primary storage can be released from inactive data by migrating it to secondary storage. Additionally this data, if requested, can be archived according to applicable law.
Do you know how much data is inactive in your storage systems?
By our software PoINT File System Analyzer you can examine your primary storage and get this information. The software is available to professional users free of charge and can be found in our download area.
It should be noted that up to 60% of your storage costs can be saved and expensive storage extensions can be prevented by implementing PoINT Storage Manager.
