Parallels et Similitudes Stockage dans un Cloud (nuage)


Cloud storage similarities (Pstorage) is highly available distributed storage (virtual SAN) with built-in replication and disaster recovery.
Pstorage virtualization platform allows the storage on top devices in material with hard drives locally and was able to unite in the storage cluster in scenarios such as virtualization using virtual machines (vessels) and / or monitoring container system (CTS). Pstorage provides rapid live migration of VMS monitoring devices and CTS through the nodes without having to copy the VM / CT data, the high-availability storage as it becomes available remotely.

Advantages

Are listed in the main Pstorage features below:
There are no special hardware requirements. Basic equipment (SATA / SAS, 1GB Ethernet drives +) can be used to create storage.

Indications of strong consistency. This makes it suitable for Pstorage via the iSCSI protocol, VM and TC operates on top of that (unlike the storage objects such as Amazon S3 or SWIFT).
  • Built-in replication.
  • Automatic recovery from disasters on the hard drive or node failure.
  • High availability. Data remains accessible even for the failure of the hard drive or the contract.
  • Optional caching SSD. SSD caches enhance the overall performance of the group to write and read operations.
  • Checksumming data and washing. Test and washing greatly improve the reliability of the data.
  • Development upon request. You can add more storage nodes to the cluster to increase its disk space. Image VM / CT size is not limited by the size of one of the hard drives.
  • Petabytes tables
  • More uniform performance materials and capacity utilization on the contract, and the contract has been taken advantage of those inactive.
  •  High performance - similar to the SAN.
