A software-defined data center (SDDC) is a facility in which all the infrastructure, such as networking, storage, and compute, is virtualized and delivered as a service. Compared to a traditional data center in which the infrastructure is defined by hardware and devices, provisioning and management of a software-defined data center is accomplished by policy-driven automation to increase the speed of resource delivery and improve efficiency.
The core components that are central to a software-defined data center are:
- Server virtualization masks physical server resources from the user. This removes the need for users to manage complex server details, increases resource sharing and utilization, and provides scalability.
- Network virtualization splits the available bandwidth into individual channels that can easily be assigned to different servers.
- Storage virtualization combines physical storage from multiple devices into one device that can be managed from a central console.
- Management and automation software enables the user to provision, control, and manage all virtualized components.
Proponents of software-defined data centers report that the benefits include:
- Improved efficiency from extending virtualization through the data center
- Increased agility from provisioning applications quickly
- Improved control over application availability and security through policy-based governance
- Flexibility to run new and existing applications in multiple platforms and clouds
- Reduced energy usage by enabling servers to run at decreased power levels or be turned off
WORD OF THE DAY:
Data Center SwitchgearA data center switchgear refers to the critical infrastructure component within a data center that facilitates the efficient and reliable distribution of electrical power to various equipment and systems. It typically consists of electrical switchboards, circuit breakers, transformers, and other protective devices, all designed to regulate and control the flow of electricity.
