What are the maximum resources available for a Server?
Virtual server configurations are subject to the following limits, according to the CPU type:
AMD CPU: Up to 62 cores and 240 GB RAM
Intel® CPU: Up to 27 Intel® cores and 120 GB RAM
A single Intel® physical core with Hyper-Threading Technology is exposed to the operating system of your virtual server as two distinct “logical cores”, which process separate threads.
Minimum: 1 GB
Maximum: 16 TB
Minimum: 100 GB
Maximum: 1 TB
Because the size of the working memory (RAM) cannot be processed during the initial configuration, newly provisioned servers with more than 8 GB of RAM may not start successfully when created from IONOS Windows images.
We recommend initially setting the RAM size to 8 GB; RAM size can then be scaled as needed after the initial provisioning and configuration.
What are the Availability Zones?
IONOS data centers are divided into separate areas (also known as "fire zones"), called Availability Zones.
You can enhance reliability and set up high-availability scenarios by deploying redundant virtual servers and storage devices across multiple Availability Zones.
How do I change the Availability Zone?
Select the server in the DCD Workspace
Use Inspector > Properties > Availability Zone menu to change the Availability Zone
What is Live Vertical Scaling?
Live Vertical Scaling (LVS) technology permits you to scale the number of CPU cores and amount of RAM while the server is running, without having to restart it. Please note that Windows only allows scaling the number of CPU cores, but not the amount of RAM. For scaling to more than eight CPU cores, Windows requires a reboot.
You should use DCD to shut down your server completely. Your VM will then be marked as "shut down" in the DCD. Shutting down a VM at the operating system level alone does not deallocate its resources or suspend the billing.
Try to connect to your VM using the Remote Console to see if it is up and running. If you have trouble logging on to your VM, please provide our support team with screenshots of error messages and prompts from the Remote Console.
Windows users: Please send us a screenshot of the Task Manager.
Linux users: Please send us the output of uptime and top.
How do I get the root/admin passwords with IONOS images?
When using IONOS-provided images, you set the passwords yourself prior to provisioning.
Why does my newly provisioned server not start?
Newly provisioned servers with more than 8 GB of RAM may not start successfully when created from IONOS Windows images, because the RAM size cannot be processed during the initial configuration.
An error is displayed according to the server version; for example, Windows Server 2012 R2 displays the following message:
"Windows could not finish configuring the system. To attempt to resume configuration, restart the computer."
We recommend initially setting the RAM size to 8 GB, and rescaling it as needed after the initial provisioning and configuration are complete.
Which CPU architecture should I choose?
The choice of CPU architecture primarily depends on your workload and performance requirements. Intel® processors are oftentimes more powerful than AMD processors. Intel® processors are designed for compute-intensive applications and workloads where the benefits of hyperthreading and multitasking can be fully exploited. Intel® cores cost twice as much as AMD cores. Therefore, it is recommended that you measure and compare the actual performance of both CPU architectures against your own workload. You can change the CPU type in the DCD or using the API, and see for yourself whether Intel® processors deliver significant performance gains, or more economical AMD cores still meet your requirements.
With our unique "Core Technology Choice" feature, we are the only cloud computing provider that makes it possible to flexibly change the processor architecture per virtual instance.
What do I do if the cursor in the Remote Console disappears?
When the cursor disappears after logging on to the Remote Console, you can reconnect to the server using the appropriate menu entry.
What are Cloud Cubes?
For a long time, the duopoly of virtual private servers (VPS) and dedicated cloud servers dominated virtualized computing environments.
Enter Cloud Cubes — virtual private service instances — the next generation of IaaS. Developed by IONOS Cloud, Cubes are ideal for specific workloads that do not require high compute performance from all resources at all times — development and testing environments, website hosting, simple web applications, and so on.
While based on shared resources, the Cubes can rival physical servers through a platform design that can redistribute available performance capacities among individual instances. At the same time, reduced operational complexity and highly optimized resource utilization translate into lower operating costs.
m = PVPanic device is available as moduley = PVPanic device is native available in the kerneln = PVPanic device is not available
When the device is not available (CONFIG_PVPANIC=n), use another kernel or image.
How do I install the device driver for the pvpanic device on Windows?
For your virtual machines running Microsoft Windows, we provide an ISO image that includes all the relevant drivers for your instance. Just log into DCD, open your chosen virtual data center, add a CD-ROM drive and insert the driver ISO as shown below (this can also be done via CloudAPI).
Please note that a reboot is required to add the CD drive.
Once provisioning is complete, you can log into your OS by adding drivers for the unknown device through the Device Manager. Just enter devmgmt.msc in the Windows search bar, console, or PowerShell to open it.
Since this is a Plug & Play driver, there is no need to reboot the machine.
