Frequently Asked Questions
How does SDS (software-defined storage) work?
Software-Defined Storage (SDS) abstracts storage resources from hardware, allowing flexible management and scalability through software controls. SDS decouples storage management from physical devices, enabling dynamic allocation, automation, and efficient utilization of storage infrastructure. It enhances agility, scalability, and cost-effectiveness in storage solutions. xiSTORE, powered by Lustre File System and xiRAID, represents a cutting-edge SDS solution, combining high-performance software RAID with a robust file system for optimal data storage and retrieval.
Why choose SDS (software-defined storage)?
Choosing SDS (software-defined storage) offers flexibility, scalability, and cost-effectiveness as it decouples storage management from hardware, allowing for easy adaptation to changing storage needs. SDS solutions like xiSTORE, built on Lustre File System and powered by xiRAID, provide high-performance and efficient data storage solutions for diverse workloads.
What is the difference between software-defined storage and traditional storage?
Software-defined storage (SDS) revolutionizes storage systems by separating management software from hardware, offering dynamic scalability and flexibility. SDS abstracts storage functions into software layers, enabling efficient resource allocation and seamless integration with modern data centers. In contrast, traditional storage tightly couples hardware and software, limiting scalability and agility. Proprietary hardware configurations hinder adaptation to evolving storage needs, making management labor-intensive. xiSTORE embraces SDS principles, delivering enhanced performance, scalability, and manageability for modern workloads.
