Zerowait now offers Proxmox! Read here to learn how fast the ROI can be when compared with the new VMware pricing model. A ready-for-prime-time solution out of the box, Proxmox is available for free or with fully supported enterprise levels. Because ZFS is natively integrated, it is perfect for SimplStor. See below for more details.
Proxmox Virtual Environment
Proxmox Virtual Environment (Proxmox VE), with native ZFS, is an enterprise server manager for virtualization. It integrates Kernel-Based Virtual Machine (KVM) hypervisor, Linux Containers (LXC), software-defined storage and networking functionality on a single platform. Its easy to use web-based user interface allows simple management of Virtual Machines (VMs) and containers, high availability, replication, immutable storage and built-in disaster recovery tools. By combining two virtualization technologies on a single platform, Proxmox VE offers maximum flexibility: Use KVM full virtualization for Windows and Linux images, while at the same time provide lightweight containers to run conflict-free Linux applications.
Yes, the Source Code is Free
Proxmox Virtual Environment source code, based on Debian GNU/Linux with a custom Linux Kernel, is free, released under the GNU Affero General Public License, v3 (GNU AGPLv3). This means that you are free to use it and inspect the source code at any time, even contribute to the project yourself. (Source)
Kernel-based Virtual Machine (KVM)
KVM merges a kernel module into the main Linux kernel. With KVM you can run multiple OS, such as Windows and Linux, in virtual machines (VMs) each controlling their own virtualized CPU, network, disk and other resources.
Container-based virtualization and Linux Containers (LXC)
Only Linux distributions can be installed in containers. These LXC are tightly integrated with Proxmox VE, such that they can use the same network, clustering and storage resources as virtual machines. Proxmox’s goal has been to offer the benefits of using a VM without the additional overhead.
Central Management via Web UI
All management tasks can be performed through the user interface (UI). The central web interface is based on the ExtJS JavaScript framework and can be accessed from any modern browser. In addition to management tasks, it also provides an overview of the task history and system logs of each node. This includes running backup tasks, live migration, software-defined storage, or HA triggered activities. The multi-master tool allows you to manage your whole cluster from any node of your cluster; you don't need a dedicated manager node. A mobile version is also available.
Clustering
While many people start with a single node, Proxmox Virtual Environment can scale out to a large set of clustered nodes. The cluster stack is fully integrated and ships with the default installation. Proxmox VE uses the unique Proxmox Cluster File System (pmxcfs), a database-driven file system developed by Proxmox. The pmxcfs enables you to synchronize configuration files across your cluster. By using Corosync, these files are replicated in real time to all cluster nodes. The file system stores all data inside a persistent database on disk, nonetheless, a copy of the data resides in RAM. The maximum storage size is currently 30 MB - more than enough to store the configuration of several thousands of VMs. Proxmox VE is the only virtualization platform using this unique cluster file system, pmxcfs.
Live/Online migration
With the integrated live/online migration feature, you can move running virtual machines from one Proxmox VE cluster node to another, without any downtime or noticeable effect from the end-user side. Administrators can initiate this process from either the web interface or the command line. This enables you to minimize downtime, in case you need to take the host system offline for maintenance.
Unique multi-master design
To simplify the management of a cluster, you can carry out maintenance tasks cluster-wide, from any node. The integrated web-based management interface gives you a clean overview of all your KVM guests and Linux containers across your cluster. You can easily manage your VMs and containers, storage or cluster from the GUI. There is no need to install a separate, complex, and pricey management server.
Authentication
In Proxmox VE, access control lists, aka role-based permissions, may be assigned using standard means. You can also create and maintain authentication realms under LDAP, Microsoft Active Directory, Linux PAM, OpenID Connect and an integrated Proxmox VE authentication server.
Proxmox VE High Availability (HA) Cluster
The entire Proxmox VE multi-node HA Cluster can be easily configured from the integrated web-based user interface. Proxmox VE HA Manager monitors all VMs and containers in the cluster and automatically comes into action if one of them fails. Enterprise Support Proxmox VE is a perfect fit for your enterprise environment. The production-ready feature-set is simple to manage and helps you to increase efficiency and reduce complexity in your data center. Enhanced commercial support services and training allow you to keep your business running.
