In AOC, management is structured hierarchically into three levels: organization, data center, and cluster, from top to bottom.
An organization, which represents a company, serves as the highest management level in AOC. An organization can include multiple data centers and clusters, allowing for shared upgrade files, VMTools images, and more. You can specify an organization name and modify it.
Data centers refer to the physical data centers dispersed across different cities or located in different geographic locations within the same city. Generally, a data center contains at least one cluster. You can create a data center or edit the data center name under a specific organization in AOC.
A cluster is typically located within the physical data center and consists of at least three hosts. Generally, a cluster belongs to a data center in an organization, but it can also exist independently in an organization.
In AECP, Arcfra Cloud Operating System (ACOS) is deployed using a hyperconverged architecture. The hyperconverged ACOS clusters and ACOS active-active clusters provide distributed block storage, compute virtualization, network virtualization, data protection, and operational management services.
Depending on the virtualization platform chosen during deployment (AVE or VMware ESXi) and whether to enable the active-active feature in the ACOS cluster, ACOS clusters can further be classified into ACOS (AVE) clusters, ACOS (VMware ESXi) clusters, ACOS (AVE) active-active clusters, and ACOS (VMware ESXi) active-active clusters.
ACOS (AVE) active-active clusters and ACOS (VMware ESXi) active-active clusters are deployed in a stretched form, each comprising two availability zones and one witness node. These availability zones are typically located in two separate data centers within the same city at a significant distance.
You can associate ACOS clusters with AOC to manage them in a unified manner. When managing ACOS clusters, it is recommended to organize AOC hierarchically according to the actual organizational structure of the company. For example, if cluster A and cluster B are both located in a London data center, you can create a London data center within AOC and associate cluster A and cluster B with this data center for unified management.
