Proxmox VE 3.4 with ZFS File System Released

Download this press release in PDF in English and German.

Vienna (Austria) – February 19, 2015 – Proxmox Server Solutions GmbH today released version 3.4 of its open source server virtualization management platform Proxmox Virtual Environment (VE). Highlights are the integrated ZFS file system, a ZFS storage plug-in, hotplug and NUMA support (non-uniform memory access), all based on latest Debian Wheezy 7.8. The Proxmox developers considered many user feature requests and added many GUI improvements like start/stop all VMs, migrate all VMs or disconnect virtual network cards.

The integrated ZFS (OpenZFS) is an open source file system and logical volume manager in one, allowing huge storage capacities. Starting with the new ISO installer for Proxmox VE 3.4, users can now select their preferred root file system during installation (ext3, ext4 or ZFS). All ZFS raid levels can be selected, including raid-0, 1, or 10 as well as all raidz levels (z-1, z-2, z3). ZFS on Proxmox VE can be used either as a local directory, supporting all storage content types (instead of ext3 or ext4) or as zvol block-storage, currently supporting KVM images in raw format (with the new ZFS storage plugin).

Using ZFS allows advanced setups for local storage like live snapshots and rollbacks but also space and performance efficient linked templates and clones. The ZFS storage plugin in Proxmox VE 3.4 complements already existing storage plugins like Ceph or the ZFS for iSCSI, GlusterFS, NFS, iSCSI and others.

The new hot plugging feature for virtual machines allows installing or replacing virtual hard disks, network cards or USB devices while the server is running. If hot plug is not possible, the new “pending changes” (marked now in red) show that the changes need a power off to be applied - the admin always overviews the actual status of his changes.

“ZFS in Proxmox VE 3.4 is absolutely powerful,” says Martin Maurer, CEO of Proxmox Server Solutions. “Users can replace cost intense hardware raid cards by moderate CPU and memory load, and it’s combined with easy management.” Maurer summarizes “By using ZFS, our users can achieve maximum enterprise features with low budget hardware – but they should not forget to add a SSD for a fast cache (L2ARC and ZIL).“
