Software Defined Storage is an approach to data storage in which the storage software is decoupled from the hardware and can run on industry standard hardware procured independently of the software. Dell EMC offers the industry’s broadest Software Defined Storage portfolio, featuring by Intel® Xeon® processors, with solutions for scale-out file storage, block storage and object storage and software defined automation and management of traditional arrays.
What is a Software Defined Data Center?
A Software Defined Data Center (SDDC) is a data center in which infrastructure is virtualized and delivered “as-a-service”. SDDC is combination of software-defined networking – management of traffic, software defined compute – management of workloads and software-defined storage – management of data. Traditional enterprise applications can be supported in a more flexible and cost effective manner.
What is File Storage?
File storage refers to the storage of unstructured, file-based data. This data can be generated from and used to support a wide range of applications and workloads. File data is presented to both the system storing it and the system retrieving it in the same way.
Block storage is the typical native storage interface of most storage media at the driver level. A hard disk driver, for example, writes out and reads in blocks by their block address on the formatted disk. Block Storage offers better performance and speed than file level storage systems. Each block volume can be treated as an independent disk drive and controlled by external Server OS.
Object storage is a storage architecture that manages data as objects as opposed to file storage, which uses a hierarchal directory structure. An object contains data, meta-data, and a unique global identifier. Object storage is preferred for cloud applications because of its inherent ability to scale massively, accessibility via common API’s, and ability to use a namespace, which can span multiples instances of physical hardware.
