Software Defined Infrastructure

The open Ericsson Software Defined Infrastructure (SDI) extends the business agility and operational efficiency of the cloud into the hardware layer of our NFVI solution, increasing scalability, elasticity and utilization of the datacenter.

Following the ETSI model, Ericsson NFVI solution replaces vertically integrated systems with an open cloud infrastructure that hosts virtual network functions (VNFs). This dramatically improves business agility and operational efficiency.

Instead of configuring hardware into separate, statically cabled configurations that host local workloads, in Ericsson SDI, resources are pre-cabled into a common hardware pool available to all workloads across the entire infrastructure, regardless of which VIM manages them.

The pool is open and connects compute and storage resources from Ericsson, and vendors such as Dell and HP, through Ericsson SDI Networking – the common switching fabric. Regardless of how many racks the resources are distributed across or which vendor manufactured them, the hardware management is done through Ericsson SDI Manager as the single integration point.



Ericsson SDI Manager discovers compute hardware from any of our approved vendors and configures it into the common pool. It logically allocates those resources into virtual, performance-optimized datacenters (vPODs). These vPODs are used for virtual, containerized, and bare metal deployments, depending on the need of the workloads.


The vPODs are used by operators to quickly set up multiple hardware environments to support NFVI with optimized performance and utilization. The vPODs can be rapidly created, expanded, reduced, or deleted without manual reconfiguration or re-cabling. This makes it possible to provision services and scale the infrastructure up and down, in and out, in an efficient manner.



Efficient Hardware Utilization

Managing all hardware, independent of vendor, in a common pool from a single integration point with a common set of skills, tools, and procedures creates operational efficiencies and the unique capability to scale out. By providing spare capacity at the infrastructure level, instead of within each POD, a common pool reduces the hardware buffer by 50 percent.

Downloads Components in Ericsson SDI About Software Defined Infrastructure

Ericsson Software Defined Infrastructure (SDI) is a system product where the SDI Manager and SDI Networking software together with HDS 8000 hardware creates a unique value proposition for telecom operators.

Ericsson SDI Manager
The SDI Manager provides hardware management and is also the centerpiece in managing the vPOD setup including tenant management. It manages both Ericsson HDS 8000 hardware as well as compute and storage hardware from our approved vendors. An open RedFish North bound interface provides a common integration point for Ericsson and other vendors’ hardware in the common pool.

Ericsson SDI Networking
The SDI Networking software is, together with the Ericsson NRU (Networking Rack Unit) hardware, providing the networking logic to logically separate the common hardware pool into vPODs. It is powered by Pluribus Networks Netvisor® ONE operating system and the Adaptive Cloud Fabric™.

Ericsson HDS 8000 Hardware
The Ericsson HDS 8000 hardware family includes state of the arthardware for compute, storage and network. It provides the efficiency and performance levels needed for all operator needs. Please see the data sheets in the downloads section for more information.

Software Defined Infrastructure

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.

Facilitating NFV transformation to 5G

In order to increase agility, decrease total cost of ownership (TCO), and reduce complexity, 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. The SDI technology 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.
Operators use vPODs to quickly set up multiple hardware environments to support different configurations of network functions virtualization infrastructure (NFVI) with optimized performance and utilization. This capability can be used to support the implementation of pre-production 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 Ericsson 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.
