debian 13 Archiv - credativ®

The most important new features at a glance:

1. Basis: Debian 13 "Trixie" & Linux Kernel 6.14
   The foundation of Proxmox VE 9.0 is the new Debian 13 "Trixie". In combination with the latest Linux kernel 6.14, users benefit from improved hardware compatibility, increased security and overall better performance.
2. VM snapshots for LVM shared storage
   One of the most anticipated features is native snapshot support for LVM Shared Storage. This is particularly important for environments that use iSCSI or Fibre Channel SANs, as it is now possible to create snapshots as so-called "volume chains". This enables flexible and hardware-independent backup solutions. The snapshot functionality is based on QCow2 and is also available for other storage types.
3. SDN stack with "fabrics"
   The software-defined networking (SDN) stack has been expanded to include the new concept of "fabrics". This makes it easier to create and manage complex, fault-tolerant and scalable network topologies. The new version also supports the OpenFabric and OSPF routing protocols, which simplifies the setup of EVPN networks.
4. High availability (HA) with affinity rules
   New affinity rules make managing high-availability clusters more flexible. Administrators can now define whether VMs or containers should remain on the same node (positive affinity) or be distributed across different nodes (negative affinity) to increase reliability. However, for behaviour familiar from VMware DRS, we still recommend ProxLB as the tool of choice.
5. Modern and responsive mobile user interface
   The mobile web interface has been completely redesigned in Rust using the Yew framework. It offers significantly improved usability, faster loading times and allows basic maintenance tasks to be performed on the go.
6. Improvements to ZFS
   There is also good news for users who use ZFS storage pools: Version 9.0 now allows new hard disks to be added to existing RAIDZ pools with minimal downtime.
7. Expansion of metrics
   In the new version, the host metrics have been revised and expanded.

In summary, Proxmox VE 9.0 represents a solid further development of the platform. The new features and modern foundation make it an even more powerful and reliable solution for businesses and home users who value open source technology.
