Can CubeCOS integrate with existing SAN or NAS storage systems?

CubeCOS 3.1 natively supports the FC, iSCSI, and NFS protocols. Enterprise storage systems that are supported can be integrated directly. Existing storage arrays and cloud-native volumes are unified under a single interface for identification, allocation, and management. This helps organizations protect and extend the value of their storage investments.

Can CubeCOS 3.1 manage both block and file storage simultaneously?

Supports the concurrent management of NFS (file storage) and FC SAN or iSCSI (block storage). Administrators can define storage policies based on performance or cost, and workloads are automatically routed to the most suitable storage tier, regardless of protocol or vendor.

How does external storage integration accelerate workload deployment and scaling?

CubeCOS 3.1 enables independent scaling of storage and computing resources. Storage capacity can be expanded without modifying the compute layer, enabling the provisioning of new workloads on demand. This architectural separation eliminates the resource allocation bottlenecks that typically slow deployment cycles, enabling infrastructure teams to respond quickly to changing business requirements.

How does the one-click update and upgrade feature help organizations meet IT compliance and audit requirements?

Every update operation records timestamps, the scope of changes, and execution results. This creates a complete and traceable audit trail that directly supports both internal compliance reviews and external regulatory audits. Additionally, consistent patch deployment across all nodes prevents common audit issues caused by version inconsistencies, significantly reducing the workload of preparing documentation before each audit.

If an issue occurs during a CubeCOS update or upgrade, how does the system maintain service availability?

CubeCOS 3.1 continuously monitors deployment health throughout the update process and immediately displays any detected errors. You have full control over each stage of the upgrade workflow. The system architecture supports recovery procedures that are designed to minimize service disruption. This allows teams to maintain the latest security patches without compromising service availability.

What is the process for migrating workloads to CubeCOS, a VMware alternative?

CubeCOS can import virtual machine images directly from platforms such as VMware, Hyper-V, Nutanix, and Xen without rebuilding workloads. After importing the images, teams can validate their operation within the CubeCOS environment and perform the transition according to their preferred schedule. Traditional migration projects that take months and involve significant risk become controlled and structured transitions.

If my workloads are distributed across multiple hypervisors, such as VMware, Hyper-V, or Nutanix, must they all be migrated to CubeCOS at once?

CubeCOS 3.1 supports phased migration. First, teams can import and validate lower-critical workloads. Then, they can gradually migrate production systems after confirming stability. This staged migration approach reduces risk, gives teams time to familiarize themselves with the CubeCOS environment, and ensures they have full control over the migration timeline, all while avoiding operational disruption from a single large-scale transition.

CubeCOS 3.1: The Enterprise-Ready Open-Source Virtualization Platform Built for Modern IT Infrastructure

Since its official open-source release in version 3.0, CubeCOS has been committed to advancing enterprise-grade, open-source, cloud-native infrastructure.

Additional CubeCOS 3.1 Enhancements

Cloud Native Workload Integration

CubeCOS 3.1 introduces a built-in OCI Registry that provides a centralized, secure, and OCI-compatible environment for storing and managing container images, artifacts, and Helm charts.
With the platform's native image management capabilities, enterprises can control cloud-native application resources more effectively, accelerate containerized deployment processes, and enhance software supply chain security and management consistency.

Advanced Hardware Management and Operations

CubeCOS 3.1 introduces a new graphical user interface (GUI) for disk management that enables administrators to add, remove, replace, and update disk parameters while monitoring disk status in real time. The new version also includes IPMI host management, which provides centralized visibility and control of physical node hardware, thereby improving infrastructure monitoring and operational efficiency.

Internationalization Interface

To address cross-region deployment and international market demands, CubeCOS 3.1 has enhanced its UI internationalization (i18n) capabilities and now supports multiple languages, including Traditional Chinese and English. Localized user experiences improve management efficiency and facilitate cross-border team collaboration and open-source community engagement.
