DIA Data Integrity Assurance Architecture:
A New Reliability Standard
 |
Storwize's primary data compression appliances meet the most stringent requirements for guaranteed data availability, establishing a new standard for data reliability, ahead of any data reduction products on the market today.
Storwize achieved this new level of accessibility by creating the DIA Data Integrity Assurance architecture, which is being implemented across the company’s full product line. DIA ensures end-to-end verification throughout the data stream, fault detection and correction and verification of decompression reliability. |
| What is new with DIA Data Integrity Assurance Architecture? |
The Storwize DIA Data Integrity Assurance architectural innovation delivers an unmatched level of data integrity by leveraging four cornerstone technology components:
| • |
Preserving data integrity mechanisms in the network at the protocol, connectivity and storage levels; write acknowledgement from the storage is forwarded to the client only after the data was fully written; |
•
|
Ensuring reliable compression and decompression with the Storwize-developed Compression-Decompression Checksum, verifying the accuracy of every data block that the appliance compresses; |
•
|
Compressing data using proven and reliable industry-standard lossless data compression algorithms; |
| • |
Ensuring data reliability at the hardware level with Error Correction Code memory modules that combines parity bits and additional checksum to maximize data integrity. |
The multi-tiered data protection provided by the Storwize DIA Data Integrity Assurance Architecture and built into every Storwize data compression appliance is a quantum leap in guaranteeing data integrity compared to some of the data threats inherent in other data reduction technologies. Additionally, many backup data reduction technologies restrict users into pre-defined data protection constraints that often run counter to current company backup rules. Conversely, Storwize primary data compression appliances operate transparently within the customer’s existing storage infrastructure and are fully compliant with existing data protection policies and procedures.
