Ceph distributed storage

With the development of digitalization, the priority task is to ensure the integrity of large volumes of data and availability of IT infrastructure. VMmanager helps to avoid downtime caused by accidents and ensure constant availability of corporate services.

VMmanager supports Ceph network storage, which allows you to arrange storage of all data in one platform, which reduces the operating costs associated with the storage itself. This increases fault tolerance of the infrastructure and reduces the time when the system remains unavailable (RTO).

How Ceph works

Ceph is a distributed network storage. Its features and advantages are most evident in comparison with the standard cluster architecture.

Standard cluster architecture. Virtual machines are stored and executed on the same node.

Distributed storage. The disks of the virtual machines are stored in network storage, while the execution point is on the node

In a cluster with standard architecture, the management server has the exceptional role. During maintenance, the administrator has to move the execution point along with the disk file of the virtual machine to another server on the network. In case of failure, the virtual machine’s data can only be restored manually from backups. Both transfer and recovery take a long time.

In a cluster with distributed storage, the execution point is not bound to a single server. The transfer only takes one click: the domain of the virtual machine is changed and the drive is simply reconnected. In case of failure, the virtual machine domain is generated and the machine is started on a running server. The VM drive is automatically connected to the new execution point.

You are no longer bound to the space constraints of a particular node. You no longer need to try to guess how much space is available at the node for backup, since all drives are now in network storage.

Integration to VMmanager

Ceph provides both file and block access interface. VMmanager supports RBD - distributed block device with kernel client and QEMU/KVM driver.

When using RBD, virtual disks are distributed to several objects and stored in this form in a distributed Ceph - RADOS storage.

How to start using Ceph in VMmanager

  1. Create a new cluster and select "Ceph" storage type.
  2. Connect Ceph storage, specify IP address, login and password.
  3. Connect the nodes.
