Parallels Cloud Storage

Parallels Cloud Storage is the flexible, scalable solution helping to increase considerably availability and performance of cloud servers.

Parallels Cloud Storage involves the free, but not used disk space on servers and creates a full-fledged cloud storage system much cheaper, than when using other similar solutions.

Consumers

Target audience of Parallels Storage - the hosting providers wishing to increase essentially availability and reliability of the servers at the same time reducing costs.

Parallels Cloud Storage is the technology of data storage which is a part of Parallels Cloud Server. With its help service providers can create the failover distributed cluster for data storage which on the performance will be comparable with SAN. At this Parallels Cloud Storage will cost much more cheaper as involves already available, but not used disk space on the available servers. It saves from the need for the selected equipment for data storage which usually is required in a case with SAN, and allows to receive the full-fledged cloud storage at the minimum costs.

Parallels Cloud Storage allows to store and start virtual machines and the containers Parallels, to exclude simple VPS because of failures of hard drives and RAID, to ensure smooth operation of servers, to execute instant live migration of virtual servers and also to expand the volume of available space, without being limited to the volume of an empty seat on a local disk.

Advantages

• The fault tolerance — is not present a uniform point of failure
• High performance — same, as at local disks
• Low cost — unoccupied disk space turns into the cloud storage.

Main Functions

Expansibility

• Provides the high performance and expansibility to petabytes.

Hot connection

• Allows to add additional servers and devices with ease.

Fault tolerance

• Users can set the reservation level necessary for them, and Parallels Cloud Storage will automatically detect faulty servers or disks and to recover this set level. In recovery time the cluster quickly adjusts the work, allowing to avoid interruption of data access for clients.

Automatic recovery

Automatically recovers the damaged, lost or unavailable copies of data in case of failure of a disk or the server.

High reliability

Excludes interruptions in service of end users in case of fault of the server. At failure emergence a system automatically switches to backup copies of data and can quickly resume service on other physical computer.

Data protection

• Allows to use checksums and verification of user data. Also executes background check and error correction to guarantee integrity and correctness of data.

SSD caching

Much increases data processing rate, increasing efficiency of use and capacity of the equipment.

Balancing

When new are added to a cluster or the servers which earlier left an operation return, there is a complete reorganization of balance of space in a cluster.
