The needs of a modern infrastructure are constantly growing: the demand for application scalability requires companies to look for solutions to configure a virtualized environment on premises or to move to a cloud infrastructure, especially when servers and storage spaces are not they are more sufficient. The cost for virtualization can be discouraging and this is where open source solutions come into play, such as oVirt and Gluster which allow you to virtualize an environment effectively and free of charge, creating a hyperconverged infrastructure, in which the processing, storage and network resources they are all located on the same servers, managed from a single interface.

Prerequisites Chinese Student Phone Number List At the hardware level it will be necessary to have: at least 3 servers with the following characteristics: At least 32 GB of RAM More than 256 GB of storage Dual network interface controllers (NICs) and at least one 10 GiB port Network switches Media Access Control (MAC) configured and DNS configured At the software level , the necessary components are: oVirt: Open source virtualization software management solution with all the enterprise-level features you need, such as hosts, virtual machines (VMs), network management, high availability and real-time migration.
Gluster FS, a scalable, open-source distributed storage capable of highly available petabyte-scale storage on common hardware. How does the virtualization system work? Gluster and oVirt work together to provide a hyperconverged solution: each server provides both hypervisor and storage functionality, with VM disk images stored in the Gluster volume. How does Gluster work? The volume with FS Gluster allows you to archive data on multiple servers while presenting itself as a single namespace for the clients who access it. In this solution, the Gluster volume is configured on the three servers as a replica-3 volume, meaning that every bit of data written, is replicated to two other servers to provide redundancy and resilience against server outages. Gluster volumes can also be configured as arbiter volumes, i.e. with significantly lower storage requirements than replica-3 volumes, since this volume only contains the metadata necessary for replication unlike replica-3 volumes which contain the actual data. An arbiter volume cannot be used for virtualization.
