ZStack Cloud 5.3.0 makes the following optimizations on VPC vRouter and load balancer.

Provides openEuler vRouter/LB Image and Supports System Changing with One Click

Starting from ZStack Cloud 5.3.0, the official website provides an openEuler 22.03 version of the vRouter/load balancer image. VPC vRouters and load balancers that were using the VyOS 1.1.7 OS can change their OS to openEuler 22.03 with one click.

Supports Attaching SR-IOV NICs to VPC vRouters/LBs

Starting from ZStack Cloud 5.3.0, VPC vRouters and dedicated performance LB instance using the openEuler 22.03 can enable SR-IOV during network attachment. This feature allows the passthrough of VF NICs to improve network bandwidth, PPS, and reduce latency. VPC vRouters and LB instance can be hot-migrated with VF NICs, ensuring business continuity.

The specific scenarios where SR-IOV can be enabled are as follows:

• VPC vRouter:
  • Supports enabling SR-IOV for the default public network during creation (only supported in scenarios where public and management networks are deployed separately).
  • Supports enabling SR-IOV for public and VPC networks when attached.
• Load Balancer: Supports enabling SR-IOV for both frontend and backend networks when creating a dedicated performance load balancer.

To enable SR-IOV, the following hardware requirements must be met:

• The corresponding L2 network for the L3 network must have SR-IOV network acceleration mode enabled.
• The physical NIC corresponding to the L3 network must have available VF NICs.

Starting from ZStack Cloud 5.3.0, a new HBA Device list is added to Associated Resource tab. You can view the FC-HBA devices on the host and their details, including device name, port type, port state, port speed, supported speed, and supported classes.

The platform automatically creates a default alarm Host FC-HBA Port Status Abnormal, which sends an alarm notification when an FC-HBA port is detected to be in a non-Online state.

Additionally, you can add FC-HBA Link Failure Count and FC-HBA Link Signal Loss Occurrence Count alarms to monitor the signal stability.

On the Create Resource Alarm page, after choosing a metric item, you can select multiple hosts and specify an NIC for each host. Each specified NIC can have its own individual alarm trigger rules configured, or if not individually configured, the NICs can use the uniform trigger rule set at the bottom of the page. This enhancement improves the flexibility and convenience of platform O&M.

Starting from ZStack Cloud 5.3.0, the application market introduces a new default application ZStack Component Service Monitoring Suite, which supports one-click deployment. This service helps visualize the status of services on management and compute nodes, such as UI service, monitoring collection service, zsha2 service, database service, host virtualization service, and host agent service. This service help users obtain more intuitive and comprehensive operational information about the Cloud platform, improving the O&M convenience.

In previous versions, ZStack Cloud already provided the built-in documentation in the help center, offering real-time graphical guidance. ZStack Cloud 5.3.0 makes the following optimizations on the help center documentation.

Document Directory Tree and Breadcrumb Path

Starting from ZStack Cloud 5.3.0, the help center offers a comprehensive document directory tree. You can preview the entire content of the documentation through the directory and quickly locate the required sections.

Once a section is accessed, the page header will display the breadcrumb path for that section, allowing you to easily navigate back to the previous section or return to the homepage.

Recent Search History Increased to 10 Entries

Starting from ZStack Cloud 5.3.0, the help center search box can retain the last 10 document search records. This allows you to quickly review your recent search results.

ZStack Cloud 5.3.0 makes the following optimizations on alarm messages and task progress bars.

Supports Alarm Message Convergence

Starting from ZStack Cloud 5.3.0, the platform supports the convergence of alarm message queues: If different resources trigger the same alarm within 4 seconds, the platform will only display one alarm message. By clicking on this alarm message, you can view information about all the resources that triggered the alarm. This prevents the accumulation of alarm messages on the page during sudden bursts of alarms.

Auto-Collapses Progress Bar After 5 Seconds

Starting from ZStack Cloud 5.3.0, for operations that do not complete within 5 seconds, the progress bar will automatically collapse after 5 seconds. This avoids long-term obstruction of the upper right corner of the page. After the progress bar collapses, you can click Task on the main menu to continue monitoring the task progress.

Resolves Overlapping Between Alarm Messages and Task Progress Bars

ZStack Cloud 5.3.0 resolves the overlapping issue between alarm messages and task progress bars during the same time period. After optimization, you can now view complete alarm messages and task progress bars separately in the top-right corner of the page.
