Instance-Cluster Binding Mechanism Optimization: Supports enabling Instance-Cluster Binding at the cluster level, simplifies binding logic, and enhances resource scheduling and operational convenience.
Supports Ceph Block Storage Volume as Elastic Baremetal System Volume: Improves system volume storage performance and avoids single points of failure through multi-path mechanisms, ensuring business continuity.
Supports Elastic Baremetal Instance Backup: Supports creating backups for elastic baremetal system volumes (block storage volumes) and data volumes, with one-click recovery to provide security for business data.

Instance-Cluster Binding Mechanism Optimization
ZStack Cloud 5.5.6 optimizes the instance-cluster binding mechanism.
Supports Enabling Instance-Cluster Binding at the Cluster Level
On the cluster details page, choose Advanced Settings and enable Instance-Cluster Binding. Then, all new instances created in this cluster inherit this configuration by default. Based on the Instance Binding Policy, they must or are prioritized to start in this cluster. Affected instance types include: VM instances, VPC vRouters, load balancer instances, advanced monitoring servers, and SDN instances.
You can also enable or disable Instance-Cluster Binding for individual instances. Once individually enabled or disabled with this switch, the instance is not affected by this cluster setting.Figure 1. Cluster Setting: Instance-Cluster Binding
Binding Policy Optimization
ZStack Cloud 5.5.6 optimizes the complex instance-cluster binding logic. After optimization, two instance-cluster binding policies are supported.
Hard: Instances must start in the current cluster. If no available hosts exist in the current cluster, startup fails. Also, manual migration to other clusters is not allowed.
Soft : Instances are prioritized to start in the current cluster. If no available hosts exist in the current cluster, instances can start in other clusters. Also, manual migration to other clusters is allowed.
You can set Instance Binding Policy in Advanced Settings on the cluster details page. This policy applies to all instances with Instance-Cluster Binding enabled in this cluster.
VNC Console Supports Full-Screen Mode and Small-Dot Cursor
Starting from ZStack Cloud 5.5.6, the VM instance VNC console supports full-screen display and small-dot cursor. This maximizes screen space utilization, eliminates visual distractions, and improves the experience for detailed console operations.
