Supermicro Nebulon Cloud-Defined Storage Solution

Cloud-based & AI-Op Management, Your Data & Your App Server On Premises

Solution Overview

Cloud-Defined Storage is a SaaS-based approach for on-premises, server-based enterprise storage that automates storage operations—no external array needed.

Cloud-Defined Storage (CDS), eliminates the need for a fibre channel SAN and flash storage array with a cloud-managed, server-based enterprise storage installed in Supermicro servers.

CDS is powered by a PCIe-based card called the Nebulon Services Processing Unit (SPU) pre-installed on Supermicro’s Ultra platform and a cloud-based control plane called Nebulon ON. The SPU runs a full stack of enterprise data services for shared or local storage applications, connects directly to the SSDs inside the server, and provides all the storage services needed for VMware or Linux-based applications running on that server.

Unlike Hyper Converged Infrastructure (HCI), no Nebulon software is installed on the server so the OS restrictions and server overhead of HCI simply don’t exist. CDS supports any OS or hypervisor, and VMs or application loads get 100% of the server’s CPU, memory and networking.

CDS administration is done entirely from the Nebulon ON cloud control plane. Automated software updates, AI-assisted remote monitoring and administration, and fleet management are all standard with the Supermicro CDS solution.

Solution Benefits

  • Reduce operational overhead by up to 75%
    Benefit from AI-assisted analytics and administration, powerful automation at-scale and software updates as-a-service with cloud-based management
  • Reduce storage costs by up to 50%
    Eliminate the expense and complexity of storage arrays and 3-tier architectures
  • Use 100% of your server for any application, any OS
    Support critical workloads without the server CPU/memory/network overhead of HCI and SDS—run any virtualized, containerized, or bare metal applications
  • No new vendor required
    The Nebulon solution and support is available as a server option from Supermicro

Nebulon ON: single-API endpoint in the cloud

  • Application owners self-provision infrastructure with customizable application templates tailored for their application clusters
  • AI-assisted administration provided through the cloud
  • API-driven automation provides universal insights and simple automation at your fingertips
  • Always up-to-date with cloud-delivered software

Nebulon Services Processing Unit (SPU)

Unlike PCIe accelerators that only offload specific storage functions, SPUs run the entire suite of enterprise data services that external storage arrays run. SPUs connect to server storage media and do not consume any server CPU/memory or network resources to run software on the application server. This makes the SPUs an ideal fit for enterprise applications in any operating environment, including container, hypervisor and bare-metal.



An AWS Nitro-like, plug and play card in your application servers transforms internal SSD capacity to shared and local enterprise-class storage, runs all enterprise data services, is hypervisor/OS agnostic and consumes ZERO server resources.
API-Driven Automation

API-Driven Automation

A cloud-control plane with API-first, AI-assisted administration provides simple automation, at-scale management including fleet management, predictive analytics, global insights and automated software updates.
Storage Operations as a Service

Storage Operations as a Service

IT Administrators can easily deliver operations as-a-service. Initiate immediate action on predicted issues, anticipate issues and prevent service disruption. New features and enhancements are available instantly through cloud-delivered updates “as-a-service”.
Self-Service Infrastructure

Self-Service Infrastructure

App owners can finally provision their own storage. With customizable application templates tailored for customer’s application clusters, eliminate the guesswork in configuring infrastructure and produces repeatable and reliable infrastructure services for modern, mission-critical workloads.

Use Cases
