Storage for cloud environments

Storage is one of the critical parts of any cloud environment. It should be easy to provision, fully accessible and reliable as possible. The question is how do you do it without going broke?

Commodity hardware

The answer; use commodity hardware with Open Source software to turn it into an affordable distributed network storage. With Disaster Recovery Online Solutions SDS you get highly available block storage for VMs and containers in your IaaS or PaaS system.

Enterprise virtualization

From the storage's point of view an enterprise virtualization system has the same requirements as a cloud environment. The provided storage needs to tolerate hardware failures.

Virtual pools

Virtual pools are defined in the driver/connector configuration. Configurable properties are; replica count or fixed storage host assignment. Example names: Disaster_Recovery_Online_Solutions_ssd_3_replicas, drbd_hd_alice_bob.

Logical volumes

Management operations on logical volumes like creating, deleting, snapshotting and resizing are available from the cloud software's GUI.

Node Management & Tuning

The cloud software is not aware that the storage system contains multiple nodes. Therefore node management like adding nodes and removing nodes has to be performed with the Disaster Recovery Online Solutions Manage CLI tool. Also Disaster Recovery Online Solutions fine tuning is done using the Disaster Recovery Online Solutions Manage CLI.
