Software-Defined Storage (SDS)

An SDS (software-defined storage) refers to a software controller that is used for managing and virtualizing a physical storage for the purpose of controlling the way in which data is stored.

  1. Software-Defined Storage (SDS)

  2. Table of Contents • Software • Storage Area Network • Software-defined Storage (SDS) • Server Operating System • Specifics Delivered by SDS • Key Features of SDS • Types of SDS • Benefits of SDS • Outcome of a Move to SDS

  3. Software • A set of programs (sequence of instructions) designed for the purpose of carrying out a well-defined function is called a software. Software can be of two types, application software and system software.

  4. Storage Area Network A high-speed network that is used at the block level for providing access to data storage is referred to as a SAN (Storage Area Network). With its aid servers are connected to storage devices, such as RAID hardware, tape libraries and disk arrays. Any simple SAN consists of a SAN switch, a server, a storage device, SAN management software and cables that are used to connect the various components. Usually a SAN will use various switches, servers and storage devices. Bridges, routers and gateways are also included for the purpose of extending SAN over wide areas. The topology of SAN is based on the requirements of an organization.

  5. Software-defined Storage (SDS) • An SDS (Software-defined Storage) refers to a storage architecture that aims to separate storage hardware from the software that is used to manage it. Every SAN (Storage Area Network) or NAS (Network-attached Storage) device that exists inside a data center is unified and managed by a software-defined storage. SDS, which is developed as an industry standard, helps to ensure enterprise-level functionality. It can run on either virtual machines or on the server operating system and does not depend on proprietary software or hardware.

  7. Server Operating System • A server operating system (server OS) refers to a type of operating system that has been designed specifically for the purpose of running on servers that function in a client/server architecture in order to serve a network’s client computers’ requests. • In the context of servers, let us digress and touch upon briefly the topic of web servers, which are provided by web hosting companies for storing, processing and delivering web contents. Web hosting companies provide all the necessary services for making websites accessible. Terms such as “Linux Dedicated Hosting”, “Windows Dedicated Hosting” and “Linux Shared Hosting” refer to some of the various types of web hosting services.

  8. Specifics Delivered by SDS Usually a software-defined storage provides the following- • Standard Interfaces • Scalability • Automation • Transparency • Virtualized data path

  9. Key Features of SDS The main features of an SDS are mentioned below. • Automation • Virtualization • Flexibility • Scalability • Interoperability • Enhanced storage performance • Lower upfront costs

  10. Types of SDS The main types of SDS that exist are as follows- • Container-based • Hypervisor-based • Distributed file systems meant for object storage offload • HCI software • Scale-out storage for data that is unstructured

  11. Benefits of SDS The major benefits of an SDS are mentioned below. • Freedom with regard to the choice of hardware which runs storage services • Automated adjustments that depend on capacity requirements • Creation of storage infrastructure by combining data sources • Cost-efficiency and scalability • Freedom from hardware vendor lock-in

  12. Outcome of a Move to SDS A move to a software-defined storage results in the following- • Enhanced efficiency for businesses • Improved visibility • Data center automation
