Abstract

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.

Claims

the data object comprises an addressable set of data; and

the sub blocks comprise subsets of data into which the data object is disassembled;

receive a plurality of measured temperatures from a plurality of temperature sensors, each temperature sensor associated with a corresponding storage element of a plurality of storage elements;

identify specific storage elements from the plurality of storage elements based on the plurality of measured temperatures; and

coordinate writing of the plurality of sub blocks to the specific storage elements responsive to one or more measured temperatures for the specific storage elements from the plurality of measured temperatures being within a predetermined allowable temperature range.

2. The controller node according to claim 1, further comprising:

a communication interface to connect to a data communication network,

wherein the instructions further cause the controller node to receive the data object via the communication interface.

3. The controller node according to claim 2, wherein the instructions further cause the controller node to send, via the communication interface, a share of the plurality of sub blocks to a storage node connected to the data communication network.

4. The controller node according to claim 3, wherein the instructions further cause the controller node to:

identify the storage node based on a measured temperature of the plurality of measured temperatures.
