From the navigation pane, select System > Advanced > System Parameters > Basic Parameters.
Click the icon next to Basic Parameter Settings, configure the parameters as described in "Parameters."
Click Save.
User Idle Timeout: Specify the idle timeout for the users. An operator automatically logs off of the system when the idle timeout expires.
Max. Online users: Specify the maximum number of online users. 0 indicates that the number of online users is not limited.
Per-User Concurrent Connections: Specify the maximum number of concurrent connections initiated by a user. The default is 10.
Login Failure Lockout Period: Specify the time period during which the IP address that a user uses to access the system is forbidden from logging in to the system. The timer starts after the user fails to log in to the system consecutively for the specified times.
Max. Login Attempts: Specify the maximum number of allowable consecutive login failures. If a user fails to log in to the system for the specified times, the user's IP address cannot log in to the system within the specified time period. The default is 3.
System Log Level: Select a log level. Options include Error, Warning, and Info.
Operation Log Lifetime: Specify the time period within which operation logs cannot be deleted.
VM IPv6 Address Management: Select whether to enable IPv6 address configuration for VMs. The default is Disabled. If you select Enabled, you can set the IPv6 address for VMs during VM creation, VM modification, or desktop deployment. If you select Disabled, the VM IPv6 address configuration options are hidden, but the IPv6 address configuration for VMs still retains.
Upload/Download Temporary Directory: Specify the directory for temporarily save files during upload or download. For example, files uploaded in file distribution will be saved in this temporary directory. The default is /vms/tmp. The temporary directory cannot be /, /vms, /var, /root, or /home. The temporary directory will be cleared regularly. Please do not use it to save user data.
Memory Check: Select whether to enable memory check for VM deployment. If you select Enabled, the total memory size of all VMs deployed on a host cannot exceed 80% of the memory size of the host. The system will check the memory of a host while adding, cloning, or deploying VMs on the host.
Shared Storage Fault Action: Select the action to take when the shared storage of a host fails. Options include Restart Host and Do Not Restart Host. If you select Do Not Restart Host, you must enable HA for the cluster.
Dashboard Refresh Interval: Set the interval for the system to automatically refresh the data of all items on the dashboard. Options include 5 seconds, 10 seconds, 30 seconds, 1 minute, and 5 minutes. The default is 5 minutes.
CPU Overcommitment: Select whether to enable CPU overcommitment. Options include Enabled and Disabled. The default is Enabled. If you select Enabled, the number of vCPUs bound to the physical CPUs of a NUMA node can exceed the number of the physical CPUs. If you select Disabled, the number of vCPUs bound to the physical CPUs of a NUMA node cannot exceed the number of the physical CPUs.
Host Memory Reservation: Configure whether to reserve memory for CVK hosts. Options include Enabled and Disabled. The default is Enabled. If you select Enabled, the system reserves 20% of the host memory or 10 GB host memory (whichever is smaller) for the CVK hosts. If the different between the free memory on a host and the memory used by VMs on the host is smaller than the reserved memory, VMs cannot be started on or migrated to the host. If you select Disabled, host memory reservation is disabled for CVK hosts. VMs can be started on or migrated to the host as usual.
BT Server: Specify the IP address of the Space Console server that provides the torrent file download service. If the Space Console server has multiple IP addresses, you can change the IP address. After the IP address of the BitTorrent server changes, all torrents files are updated. Users can download the new torrent files from the new IP address of the BitTorrent server.
