PROXMOX: THE FREE SOFTWARE ALTERNATIVE FOR MACHINE VIRTUALIZATION AND HIGH AVAILABILITY
Server virtualization allows a physical server to be divided into multiple isolated virtual servers by means of a software application. Each virtual server can run its own operating systems independently.
This system can have several purposes:
1º Every time the servers, whether they are based on Intel Xeon Cascadelake Refresh processors, as in AMD Rome (EPYC 7002) or AMD Milan, have more cores or cores and more execution threads. Therefore, it is very normal for an organization or company to want to have them virtualized. Virtualization is increasingly secure and the new AMD processors allow the encryption of the memory blocks used by each virtual machine.
This entails several advantages: cost savings in the purchase of hardware and its cost of ownership, reduction of electrical consumption, mixed Windows-Linux environments, test machines for prototype, etc.
2º In HPC systems of a certain size, we can have several management servers or “head nodes”, in high availability and with shared storage, so that the fall of a server does not affect the access of the cluster by the users.
3º In critical Big Data environments, equipment can be redundant, to guarantee 24×7 operation without downtime. According to PROXMOX good practices, the ideal is to have three or more medium-sized servers, to have an N + 1 environment. That is, to have a kind of “Raid” of servers, so that in the event of a crash of one of them, the others can start the virtual machines, without degrading the performance of the system.
PROXMOX VE is an Open Source virtualization system, based on Debian and KVM, which allows its use as a free solution or with professional support, for those organizations that want greater support. SIE as Sytem Integrator and wholesaler of Gigabyte, offers turnkey solutions, where the hardware-software compatibility has been tested, to guarantee the highest efficiency and performance in the market.
Proxmox VE is a complete open source platform for enterprise virtualization. With the built-in web interface, you can easily manage virtual machines and containers, software-defined networking and storage, high-availability clustering, and multiple out-of-the-box tools in a single solution.
Additionally, PROXMOX offers other enterprise-grade utilities such as Proxmox Backup Server, an enterprise backup solution for backing up and restoring virtual machines, containers, and physical hosts. By supporting incremental and full mirror backups, Proxmox Backup Server significantly reduces network load and saves valuable storage space. With strong encryption and methods to ensure data integrity, it offers a solution when backing up data, even in cloud environments, which are not completely reliable.
In modern data centers, the main focus is to minimize downtime and keep data safe. For this reason, backup software is among the most essential infrastructure components you can invest in. To increase productivity, the easy-to-use Proxmox Backup Server enables you to efficiently backup your data in a space-saving manner, restore it to flash, and effectively reduce working hours thanks to simplified management with a user-based interface. Web.
Our company offers turnkey hardware-software solutions, virtual machine migration tasks from other environments, training courses and everything your IT team needs, allowing you to save on time, resources and maintenance costs, your virtualization system , with professional services.
SIE Ladon servers implement redundancy as standard both at the level of power supplies and disks, offering a 3-year on-site warranty and being able to contract PROXMOX maintenance in this same period and optionally extend it up to 5 years. As standard we offer 9×5 services (9 hours a day, Monday to Friday), with replacement of NBD parts (next business day), being able to contract 24×7 services, for critical management environments, through our partner IECISA and its call center services .
In addition, European Computer Systems has given a workshop on Proxmox by the hand of our systems technician Javier Viejo, a great expert in VMWARE solutions, Microsoft HyperV, etc.
