AVE CSI Driver is a CSI driver addon developed by Arcfra that complies with the K8s CSI specification. In ACOS hyperconverged scenarios, it provides persistent storage capabilities for the AKE management cluster and workload clusters (VM-based workload clusters). It implements lifecycle management of virtual volumes attached to AVE virtual machines (that is, nodes of workload clusters), and supports dynamically creating and mounting AVE virtual volumes in K8s clusters through PersistentVolumeClaim for K8s Pods to use.
AVE CSI uses AVE virtual volumes to implement K8s PersistentVolumes. An AVE virtual volume actually corresponds to an iSCSI LUN, which further corresponds to an ABS volume, and has the high-performance advantage of IO locality in a hyperconverged system.
