Number of VMs running and protected in a high availability cluster
2048 pcs
Recommended maximum number of VMs per platform
(if this limit is exceeded, performance may be degraded)
25000 pcs
Maximum number of VMs per platform
(the functionality of a platform with this number of VMs has been tested, but performance may be significantly degraded)
65535 pcs
*maximum number of nodes the configuration has been tested with
**tested on a configuration with 350 nodes
***adding more IP-addresses is possible, but the performance of the VM with this configuration is not guaranteed
****the maximum virtual disk size depends on the storage file system. For example, when using ext4 with the default block size (4 KB), the maximum disk size would be 16 TB
*****it is possible to create a GPT disk up to 9.4 ZB via the platform API, but the operability of GPT disks larger than 9.4 TB has not been tested
Note:
The VMmanager virtualization platform guarantees compatibility with any software and hardware complex that meets the software and hardware requirements of the master and the nodes .
