CaaB DevOps Team Features Announcements:
Below are the details of our latest changelog for the white-label Cloud Web host Manager (CWHM) platform. Please reach out to your Account Manager directly with any questions.
- Hot Add CPU: This feature allows administrators (and users with configure permissions) to increase CPU allotment while the VM is running.
Note:
- This feature is not enabled by default for existing or new servers, it must be activated manually within the CLOUD WEB HOST MANAGER (CWHM) White-label Platform.
- My Cloud > Servers > Select Server > Configuration Tab > Show Advanced Configuration > Enable CPU Hot Add > Update Configuration.
- Initializing this feature does require a reboot, no subsequent reboots are necessary. Please plan initial downtime accordingly.
- For servers with 4+ CPUs, the Hot Add feature affects between 2%-8% of the processor’s performance.
Conditions:
- Downgrading CPU allotment without a reboot is not currently supported.
- Windows OS – No further action is required; the CPU count is updated automatically and immediately.
- Linux OS – Use the /sys filesystem to update the state (from offline to online) for all increased CPUs. See this thread for instructions.
- Hot Add RAM: Allows administrators (and users with configure permissions) to add memory to a VM while it is running.
Note:
- Again, this feature is not enabled by default for existing or new servers, it must be activated manually within the CLOUD WEB HOST MANAGER (CWHM) White-label Platform.
- My Cloud > Servers > Select Server > Configuration Tab > Show Advanced Configuration > Enable RAM Hot Add > Update Configuration.
- Initializing this feature does require a reboot, no subsequent reboots are necessary. Please plan initial downtime accordingly.
Conditions:
- Downgrading RAM allocation without a reboot is not currently supported.
- No further action is required for Windows or Linux OS, newly allocated RAM is immediately available.
- Hot Add Storage: Allows administrators (and users with configure permissions) to increase DISK size while the VM is running.
Note:
- This feature is available to all servers without a need for specialized configuration. Requested increases are immediately updated on the server’s disks.
- Again, initializing this feature does require a reboot, no subsequent reboots are necessary. Please plan initial downtime accordingly.
Conditions:
- Downgrading disk size is not currently supported. Please reach your Account Manager with questions on decreasing disks.
- After executing a Hot Storage increase, admins will need to increase the partition of the file size to view and utilize the increased disk volume.
- For Windows OS – Disk Management > Extend Volume.
- For Linux OS – Dependent on file system. For LVM and ZFS – disk disconnection is not required. Note, if the disk increase is conducted on the main disk, it is necessary to let the system enlarge the folder. EXT4 requires disk disconnection and enlargement.
- Allocate Video Memory & Change vSCSI Controller: Allows administrators (and users with configure permissions) to allocate video memory and change the type of disk controller used for each VM (ISISAS1068, PVSCSI, etc.).
Note:
- Increasing video memory does not improve graphics performance. This feature is designed to smooth the user experience when utilizing features or applications that require increased video memory. For example, when using multiple high-resolution displays while connected to a VM.
- Within a few months’ time a new function will be implemented within the CLOUD WEB HOST MANAGER (CWHM) White-label Platform that will allow partners to upload their own VHD / VMDX / VMDK / QCOW2 images to the system. In cases of custom images, administrators will be required to configure the vSCSI controller during VM creation.
- Define Network Card Type: In use cases where a network card change is required, administrators (and users with configure permissions) can now select between VMXNET3, VMXNET 2, and E1000 interface types.
These features, and feature requests planned for the near future, are designed to enhance centralized management over cloud services & infrastructure within the white-label portal. We will continue to provide our partners more control and autonomy over their cloud environments through continuous development.
- New Linux Operating System Available: AlmaLinux; is a free and open source Linux distribution, a downstream, complete binary-compatible release using the Red Hat Enterprise Linux operating system source code.
Please feel encouraged to test out this new functionality. We are looking forward to your feedback!
