To edit a CloudBoot Compute resource:
- Go to your Control Panel's Settings menu.
- Click the Compute resources icon.
- Click the Actions button next to the CloudBoot Compute resource you want to edit, then click Edit.
- On the screen that follows, change details as required:
- Label - the Compute resource's name
- Backup IP address - provisioning network IP address
- CPU Units - set the amount of CPU units assigned to this Compute resource
- Enabled - enable or disable the ability to install/boot virtual servers on this Compute resource
- Collect stats - enable or disable the ability to collect statistics for this Compute resource
Disable failover -enable or disable the VS migration to another Compute resource if this Compute resource is marked as offline by the Control Panel server.
- Failover option is not available for baremetal servers.
- If you use automatic failover with write-back caching you may lose some data in the event of a failover.
Move the Advanced slider to the right to edit advanced Compute resource settings:
MTU - specify the maximum transportation unit size. You can set the frame size from 1500 to 9000 bytes.
The maximum transportation unit (MTU) is the maximum size of a unit that can be transmitted transferred via ethernet traffic. Any data that exceed the specified MTU value will be divided into smaller units before being transferred. Utilization of jumbo frames allows you to reduce increase throughput and increase CPU utilization during large size file transfers.
SAN bonding mode - choose bonding mode type from the dropdown menu
After editing the SAN bonding mode option, it is required to reboot your Compute Resource to apply the settings.
Please note, that using more than one NIC for SAN subnet requires switch support. Please ensure that your network infrastructure supports the utilized NIC bonding and is configured correctly. By default, the utilized NICs bonding mode is IEEE 802.3ad Dynamic link aggregation which requires grouping appropriate ports together according to the section 5 Switch Configuration of Linux Ethernet Bonding Driver guide.
- Storage controller RAM - specify the storage controller RAM value (minimum 640 MB, maximum 4096 MB).
- Drives per controller - specify the number of disks per controller virtual server. You can specify from 1 to 4 disks. By default, the controller virtual server is created per 4 disk drives
- Number of cache mirrors - specify the number of cache mirrors for the compute resource
- Number of cache stripes - specify the number of cache stripes for the compute resource
- Сustom config - specify any custom commands you want to run when Compute resource is booted.
Power Cycle Command - arbitrary command string to be executed by IPMI from the CP server. If the command is entered, a new option "Power Cycle Compute resource" - which will execute the entered command will appear in Tools menu at Settings > Compute resources > Compute resource page.Currently, a command or commands should be written in one line separated with semicolon. If the command(s) is written in two lines you will receive a "fail" response, although the transaction will be performed. The power cycle command is executed on Control Panel under user onapp, this may be any script created in bash.
