What is Software Defined Storage? (A) Virtualized storage with a Fibre Channel interface (B) Virtualized storage with an Ethernet interface (C) Virtualized storage with a service management interface (D) Physical storage with a service management interface
Answer (1)
Software Defined Storage (SDS) refers to a storage architecture system that separates the software managing storage from the physical hardware where the data is stored. This separation allows for increased flexibility and scalability, as storage management becomes more agile and less reliant on specific hardware.
Among the options given:
(A) Virtualized storage with a Fibre Channel interface (B) Virtualized storage with an Ethernet interface (C) Virtualized storage with a service management interface (D) Physical storage with a service management interface
The correct choice here is (C) Virtualized storage with a service management interface.
Here’s why:
What SDS Is : SDS is an approach that enables the virtualization of storage, allowing various storage resources to be managed through a unified interface, regardless of where they are physically located. It's like creating a flexible, pooled storage resource from different hardware components.
Service Management Interface : The term 'service management interface' refers to the software layer in SDS systems, which is critical for managing data storage. It provides features such as provisioning, management, and automation of storage resources. This layer is designed to automate and optimize storage tasks without relying on the hardware's specifics.
Virtualized Storage : SDS utilizes virtualized storage, meaning it abstracts the storage hardware, allowing data to be stored, managed, and retrieved without direct ties to specific physical devices. This virtualization is what allows SDS to provide storage as a dynamic, service-oriented resource.
Comparison to Physical Storage: While SDS includes physical storage, it fundamentally transforms how storage is managed by using a software layer that acts independently from the physical components, making it distinct from traditional, hardware-centric storage systems.
In summary, Software Defined Storage is about leveraging software to manage storage needs flexibly and efficiently, utilizing a service management interface to virtualize various storage technologies.
