Business agility is provided through a software-defined infrastructure (SDI) that aggregates systems on demand from individual, disaggregated hardware components:
Make your business agile with Software-Defined Infrastructure
With aggregated software systems
Instead of traditional servers, which are hardwired configurations of resources in an individual enclosure, an aggregated software system is created specifically to provision a particular workload. It combines compute, storage, and network resources drawn from common pools. When those resources are no longer needed, they are returned to the common pools so that they are available for other aggregated systems.
Because the configuration of each system is defined in software, it is very simple to modify or scale it to make it more suitable for a different workload. If you need to launch a new web service, you can rapidly configure a system to provision it. If that service requires high performance, you can configure the system with high-performance components. If it requires high network bandwidth, you can draw as much bandwidth as you need from the central pool.
The result of the agility and flexibility that aggregated software systems provide is dramatically shorter time to market for new services.
Built from disaggregated hardware
Disaggregation is simply the logical separation of the physical resources that traditionally constitute a hardware server. In a physical server, the compute, storage, and network resources are logically connected through the operating system and associated software to form a single unit, and that unit is served by a single power system, a fan, and other supporting subsystems.
As a result, if you want to upgrade the compute resources, you have to upgrade the entire server. Or, if you want to run an application on faster compute or larger memory resources than what is on the server, you must employ high-performance computing techniques to combine the resources of multiple servers.
Disaggregation makes you agile because it lets you configure exactly the technical resources you need to pursue a business opportunity or respond to a business challenge—not more, not less. You don’t have to pay for an entire server to simply upgrade the compute resources. And you don’t have to forgo pursing a business opportunity because the cost of the hardware upgrade cuts too deeply into your bottom line.
Configured by software-defined infrastructure
A software-defined infrastructure (SDI) configures individual disaggregated hardware components into aggregated software systems. Once hardware resources are logically freed from the hardware enclosure they reside in, a management platform can arrange them in a great variety of configurations.
An SDI not only lets you build aggregated software systems, but also provision workloads on them, monitor their operation, optimize their performance, automate certain functions, and even decompose and eliminate them.
Instead of going through a lengthy procurement process for the hardware you need, the business justification for the high costs to be incurred, plus the time and expense of deployment, you simply configure the systems you need through the management platform. And, when you no longer need those resources, you can decommission the aggregated software system and return its resources to the common pool for use by other aggregated software systems.
Another capability to improve time to market is containerization, which involves packaging an application and all its dependencies into a Docker container that can be deployed anywhere in your infrastructure. Containers help you avoid vendor lock-in and the limitations of legacy infrastructures. The right type of SDI will manage your containers right along with your other provisioning options.
With Ericsson vPODs
The disaggregated architecture in Intel® RSD makes it possible for Ericsson's management platform (Ericsson Command Center) to employ the software-defined infrastructure in Ericsson Hyperscale Datacenter System 8000 to build aggregated software systems (vPODs) from pooled hardware resources.
