Hello all, I'm curently evaluating a new virtualization environment and since I generally like to stick to OSS of course Proxmox is on the list. I'm especially interested in the following features (order is prioritized, top prio comes first). I've also added examples which are contained in brackets. Cluster updates without downtimes of VMs (update a 3-node HA-Cluster without any downtime for VMs) The possibility to have tiered storage configurable via the GUI of Proxmox (SSD,SAS and NLSAS) Pin VMs to certain storage tiers ( pinning a database VM to SSD tier, a regular VM to SAS tier and an archive system to NLSAS tier) Expand single storage tiers (database VM outgrows SSD storage, so add more SSDs to Ceph) Maintenance mode of a node (evacuating all VMs from the node being maintenanced) "Hot-Add" of CPUs and Memory (Adding CPUs and RAM to the VM while it's running) Node balancing with live-migration (Avoid situations where VM count per node is imbalanced) Storage Tiering with automatic balancing (High I/O "portions" being moved from SAS to SSD tier) (optional) Support of SR-IOV/IOMMU (Passing multiple graphics cards to a single VM, passing a single graphics card to multiple VMs) My plan on building the infrastructure lies a little bit ahead in the future, so it's also interesting to me if an unavailable feature is on some roadmap or will be added soon. (~6 months to 1 year). Thanks in advance.
