To operate d.velop server applications, the following minimum requirements apply:
CPU: 4 cores
RAM: 16 GB
Hard disk: 100 GB of free storage space (depending on data volume, much more storage space may be required).
Network: Gigabit Ethernet
Note that the actual requirement depends on a number of factors. More information: Suggested configurations of d.velop documents.
for the hard disk partitions, plan for storage space both for the current installation and for future updates. When d.velop documents is updated, older program versions are stored in a backup directory. The backup directory allows the version to be restored in the event of a faulty update. With that in mind, plan for additional storage space for the backup copies.
Virtual systems are scaled like real systems. The host of the virtual systems (real hardware) requires roughly the same total hardware as the virtual systems that are operated on the host. Note the following:
You can assign more virtual CPUs than physical CPUs. This can potentially save resources compared to non-virtualized systems.
If you are operating multiple hosts with virtual systems, distribute the I/O load of the applications as evenly as possible.
If an error occurs and one host has to operate the virtual systems of another failed host, the new host requires sufficient resources.
