The requirements for cloud storage are clearly different from the requirements for conventional storage solutions. Here it is basically a matter of large capacities which have to be available redundantly, often across long geographical distances. Moreover, it is necessary to be able to analyze the data in accordance with defined standards.
Object storage fulfills these requirements. Contrary to conventional storage connections via blocks (FC, iSCSI, SAS) or files (CIFS, NFS) object storage – as the name suggests – administers objects featuring a series of additional properties. These include access rights but, above all, information concerning the redundant distribution of identical data on different storage units. Thus, redundancy is no longer linked to RAID controllers or to the replication between the individual systems, but may be defined at random and dependent on the importance of the data, even across large distances.
Together with the software manufacturer Cloudian Inc. EUROstor has defined an appliance that fits perfectly for the needs of Object Storage. Usually at least three nodes are used to support maximum redundancy.

The clusters can be extended on-the-fly practically indefinitely. In addition, unlike many other solutions, these systems support the complete S3 command set.
