Hardware Isolation Group

A hardware isolation group is a logical grouping of UHosts that ensures each UHost in the group resides on a different physical machine. Each isolation group can have a maximum of 7 UHosts in a single availability zone.

Join an Isolation group

Create a host

During the host creation process, you can optionally join a hardware isolation group.

The condition to join a hardware isolation group: the number of hosts already in the isolation group within the current availability zone must be less than 7.

If no isolation group exists, you can click Create Isolation Group, complete the creation on the isolation group page, and then select Refresh in this pop-up window.

You can also use the uhost create (UCloud Global CLI) command to create a host. Use the —isolation-group parameter to specify the isolation group. For example:

UCloud Global uhost create --isolation-group ig-rhcq22xt/ig --memory-gb 1 --cpu 1 --password test1234 --zone cn-bj2-05 --image-id uimage-35pn5v/CentOS 7.6 64 bits

Output example:

uhost[uhost-bh0fvsnh] is initializing...done

Existing hosts

Existing hosts are already supported to join the hardware isolation group.

View Isolation Groups

You can view all isolation groups via the Hardware Isolation Group tab.

In the host list, you can also expand the Hardware Isolation Group column in the “Custom List” to filter hosts by isolation group.

You can also use the isolation-group list (UCloud Global CLI) command to view isolation groups. For example:

UCloud Global uhost isolation-group list

Output example:

ResourceID   Name  Remark  UHostCount
ig-rhcq22xt  ig    ig      cn-bj2-05:1
