Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional data storage architectures, such as SAN and NAS, are not designed to support large multi-petabyte capacity levels and efficient data replication across geographically dispersed data centers, leading to challenges in data storage and protection.
Innovation Solution
The implementation of Symmetrix Remote Data Facility (SRDF) with PowerMax data storage arrays, which uses multi-core, multi-threading techniques and powerful write folding algorithms to reduce replication bandwidth requirements, enabling zero data loss remote mirroring and active-active high availability across data centers, and facilitates application control path over a remote data facility link by adjusting bandwidth of the RDF link.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If traditional SAN and NAS architectures are used, then data storage and replication across geographically dispersed data centers is attempted, but the architectures are not designed to support large multi-petabyte capacity levels and efficient data replication
Solution Approach 1:
The patent changes the parameters of the storage architecture by introducing SRDF with multi-core multi-threading techniques and write folding algorithms, transforming the system from traditional SAN/NAS to a specialized remote data facility architecture that supports multi-petabyte capacities and geographically dispersed replication
2Reliability
If data is replicated across geographically dispersed data centers, then data protection and availability are improved, but infrastructure overhead and complexity increase
Solution Approach 1:
The patent merges multiple functions into the SRDF architecture, combining data replication, protection, and application control path capabilities into a unified system that reduces infrastructure overhead while maintaining high reliability across geographically dispersed data centers
Solution Approach 2:
The SRDF architecture provides multi-functionality by enabling both synchronous and asynchronous replication modes, supporting multiple protocols (FC, FCoE, FCIP, IP), and providing both data protection and application control capabilities through a single unified system
3Productivity
If application control path is enabled over RDF link, then bandwidth utilization is improved, but link contention and performance degradation may occur
Solution Approach 1:
The patent implements dynamic QoS parameters that automatically adjust bandwidth allocation and performance thresholds based on current link conditions, replication mode, and workload characteristics, allowing the system to optimize bandwidth utilization while preventing performance degradation through real-time adaptation
