Dynamically composable computing system, a data center, and method for dynamically composing a computing system

A data center, comprising:

• at least one compute sled including a set of local computing hardware resources;
• a computing fabric including a plurality of different disaggregated memory and storage hardware resources having respective hardware characteristics;
• an orchestrator configured to schedule an application having application specific hardware requirements;
• and
• a data center resource management hardware component having access to the respective hardware characteristics of the different disaggregated memory and storage hardware resources and configured to assemble a composite computing node by selecting one or more disaggregated memory and storage hardware resources with respective hardware characteristics meeting the application's hardware requirements and connecting the compute sled to the selected disaggregated memory and storage hardware resources through the computing fabric,
• wherein the orchestrator is configured to determine, according to the application specific hardware requirements, a number of memory and/or storage tiers of the composite computing node, wherein different memory and/or storage tiers are associated with respective different hardware characteristics, and wherein the data center resource management hardware component is configured to associate one or more memory or storage hardware resources meeting the respective hardware characteristic with a respective memory or storage tier and map a respective address range to a respective memory or storage tier.

A method comprising:

• composing a computing system based on a plurality of different disaggregated computing hardware resources having respective hardware characteristics, composing the computing system to include:
• storing information on the respective hardware characteristics of the different disaggregated computing hardware resources;
• assembling a composite computing node by selecting, based on the stored information, one or more disaggregated computing hardware resources with respective hardware characteristics meeting requirements of an application to be executed on the composite computing node;
• determining, according to the requirements of the application, a number of memory and/or storage tiers of the composite computing node, wherein different memory and/or storage tiers are associated with respective different hardware resource characteristics;
• and
• associating one or more memory or storage hardware resources meeting the respective hardware resource characteristic with a respective memory or storage tier and mapping a respective address range to a respective memory or storage tier.
