A storage node for a distributed object storage system, comprising a control board configured to receive a parameter for setting predetermined allowable temperature ranges through a serial port, and sending a signal through said serial port for indicating one or more of said measurements of temperatures lies outside said predetermined allowable ranges. The control board is further configured to receive a parameter for controlling the switching on or off the storage elements through said serial port by sending a signal through said serial port to indicate which storage elements is switched on or off.

Distributed object storage system comprising low power storage nodes

The present invention is directed to a method of storing a data set in a storage system. Said storage system comprises a plurality of storage entities. The method comprises the following steps. A step of forming at least one data set block from said data set using a fragmentation entity. A step of encoding said at least one data set block by means of an encoding entity, wherein said encoding entity provides a plurality of encoded blocks based on said at least one data set block at an output of said encoding entity. And a step of distributing said encoded blocks amongst at least two of said storage entities using a distribution entity for storage thereof by said storage entities. Said encoding entity uses a rateless erasure encoding algorithm based on rateless codes for encoding said at least one data set block. The invention is further directed to a storage system and a computer program product.

Method of storing a data set in a distributed storage system, distributed storage system and computer program product for use with said method

A system may be provided which is operable to determine a routing node for a data object. The system can comprise an identifier generator operable to generate an identifier for the data object on the basis of data content thereof, and a lookup engine operable to compare the identifier for the data object to a routing table to determine a routing node for the data element.

Network routing of data based on content thereof

A backup system can be provided, which system can comprise an identifier operable to identify a data object for possible backup and a generator operable to generate an identity representation for the data object on the basis of the content thereof. The identity representation can be transmitted to a backup store where it can be tested against identity representations for previously stored objects. The system can also comprise a receiver operable to receive from the backup store an indication of whether the data object described by the identity representation has previously been stored at the backup store. The system can be operable to transmit the data object to the backup store in the event that the data object described by the identity representation has not previously been stored at the backup store.

Parallel backup

A data backup system can be operable to determine whether to send a data file segment to backup storage. The data backup system can comprise a comparator operable to compare a boundary parameter of a candidate segment proposed for sending to backup storage to a boundary parameter of a previously stored segment to determine whether the candidate segment potentially corresponds to the previously stored segment. The data backup system can also comprise a comparator operable, if it is determined that the candidate segment potentially corresponds to the previously stored segment, to compare a checksum value for the candidate segment to a checksum value for the previously stored segment to determine whether the candidate segment has previously been stored to the second location. A storage engine can be provided to send to backup storage a segment determined not to have previously been stored. Thereby a single instance store can be implemented whereby a modified segment can be identified and a segment boundary adjusted to avoid re-storage of previously stored data.
