Maximizing GenAI Potential: A Deduplication-Centric Approach to VectorDB Storage

Abstract

Generative AI (GenAI) and Retrieval-Augmented Generation (RAG) solutions require efficient methods to store, retrieve, and analyze massive datasets. A key enabler is the vector database (VectorDB), which converts raw content—such as text, images, or logs—into high-dimensional embeddings for rapid similarity searches. These workloads involve frequent embedding generation, indexing, and retrieval, placing heavy demands on storage systems to handle large I/O and maintain performance under concurrency.

This paper presents an optimal approach for deploying VectorDB on an enterprise storage array equipped with deduplication, effectively reducing redundancy and operational costs. By focusing on how vector embeddings are physically stored, we show how deduplication can minimize disk usage without sacrificing query speed. Furthermore, our solution integrates seamlessly with GenAI-RAG pipelines, providing scalable indexing, fault tolerance, and robust consistency.

To illustrate real-world impact, we examine a scenario of real-time customer feedback analysis, where organizations leverage VectorDB to draw insights, classify sentiment, and deliver rapid responses—benefiting from the storage array’s advanced data reduction. Our findings reveal that deduplication substantially lowers capacity overhead for repeated or overlapping embeddings, enabling faster model training and inference.

Overall, this work demonstrates how an enterprise-grade, deduplication-enabled storage layer can optimize VectorDB performance for GenAI-RAG workloads, empowering large-scale, real-time analytics with improved efficiency and cost-effectiveness. The resulting infrastructure is robust and high-performing, addressing the growing needs of AI-driven applications while providing a reliable foundation for future innovations.
