A basic unit of data transmission in computer networking. It is a data structure that divides data into small blocks and adds necessary information (such as source address, destination address, checksum, etc.) for effective transmission.
A hot standby node of the high-availability cluster. This node maintains strong data consistency (RPO=0) with the active node through synchronous replication. Under normal circumstances, the passive node does not directly handle workload traffic. However, when the active node fails, the passive node will be automatically promoted to the active node to take over services.
When the source virtual machine encounters a critical failure and cannot recover, the replica virtual machine takes over the services on the source virtual machine to ensure business continuity.
A persistent volume (PV) is a piece of storage in the cluster that has been provisioned by an administrator or dynamically provisioned using storage classes. It is a resource in the cluster just like a node is a cluster resource.
A persistent volume claim (PVC) is a request for storage by a user. It is similar to a pod. Pods consume node resources and PVCs consume persistent volume resources.
PF (Physical Function) is used to support and manage SR-IOV. As a full-featured PCIe function, PF can find, manage, and handle SR-IOV resources like any other PCIe devices.
A workload cluster built from virtual machine nodes and physical machine nodes, where control plane nodes are virtual machine nodes and worker nodes are physical machine nodes.
A pod (as in a pod of whales or pea pod) is a group of one or more containers, with shared storage and network resources, and a specification for how to run the containers. A pod's contents are always co-located and co-scheduled, and run in a shared context.
A mode that binds multiple physical network ports into a single logical port to enhance overall reliability and total bandwidth.
The availability zone where services primarily run when the ACOS active-active cluster operates properly.
A PV (persistent volume) is a piece of storage in the cluster that has been provisioned by an administrator or dynamically provisioned using storage classes. It is a resource in the cluster just like a node is a cluster resource.
A PVC (persistent volume claim) is a request for storage by a user. It is similar to a pod. Pods consume node resources and PVCs consume persistent volume resources.
