Software-Defined Infrastructure (SDI) provides the capability to control and configure compute, storage, and networking hardware from a central management platform into virtual performance-optimized datacenters (vPODs). The Virtual POD concept gives operators great flexibility within their NFV solutions.
Software-Defined Infrastructure facilitates NFV transformation
In order to increase agility, decrease total cost of ownership (TCO), and reduce complexity on the journey to 5G, operators are investing in network functions virtualization (NFV). During this transformation, operators will face various requirements from applications or different parts of the organization requiring a flexible infrastructure which can be adapted for a multitude of needs.
SDI is a way of providing hardware resources flexibly for various operator needs. SDI provides the capability to control and configure compute, storage, and networking hardware from a central management platform into so called virtual performance-optimized datacenters (vPODs). To do that, an advanced hardware management system is used.
What is a vPOD?
A vPOD is a dynamically created collection of interconnected hardware built from a pool of resources and can be used for any workload just as with a dedicated POD. The bare metal applications or virtualization layer and applications are then provisioned inside a vPOD. The vPODs are created with different combinations of compute, storage, and networking resources depending on the infrastructure requirements of the applications.
The vPODs are used by operators to quickly set up multiple hardware environments to support different flavors of network functions virtualization infrastructure (NFVi) with optimized performance and utilization. This capability can be used to support the implementation of pre-development environments replicating the production environment, e.g. when introducing new applications. Another use case is to create separate environments for different parts of the organization. All of this can be done using a common pool of hardware managed entirely by networking software and a hardware management system. The benefits are fast deployment of new services, improved operational efficiency and better utilization of the hardware.
Intel® Rack Scale Design
An important enabler of SDI is Intel® Rack Scale Design, which is a modern architecture that introduces the ability to efficiently pool and utilize hardware resources. Intel® Rack Scale Design extends the principles and benefits of virtualization from individual servers to the entire datacenter with a next-generation platform of standardized APIs and an emerging ecosystem of solutions to meet a broad spectrum of customer needs.
