When a change has occurred, the method continues with the DS processing module accessing de-duplication tracking data for the set of data objects. When the change is deletion of an identified data object of the set of data objects, the method continues with the DS processing module determining whether the identified data object is the only data object in the set of data objects. When the identified data object is not the only data object in the set of data objects, the method continues with the DS processing module updating the linking information to delete linking the identified data object to addressing information. |

Storage isolation using I/O authentication
Techniques are described for logically isolating data I/O requests from different operating systems (OSes) for a same multi-tenant storage system (MTSS). Techniques provide for OSes and the MTSS to obtain security tokens associated with the OSes. In an embodiment, an OS uses a security token to generate an authentication token based on the contents of a data input/output (I/O) request and sends the authentication token to the MTSS along with the data I/O request. When an MTSS receives such data I/O request, MTSS retrieves its own copy of the security token associated with the OS and generates its own authentication token based on the contents of the received data I/O request. If the authentication token generated by the MTSS matches the authentication token generated by the OS, then the data I/O request is successfully authenticated. Otherwise, if the authorization tokens fail to match, then the data I/O request has been compromised. For example, either the contents of data I/O request has been tampered with, or an entity other than the OS, has sent the data I/O request in the first place. Accordingly, the data I/O request may not be serviced by the MTSS. |

Orthogonal signal demodulation
A modulation transmission technique comprises placing orthogonal subcarriers across an arbitrary-wide band of frequencies without a fixed pre-defined center frequency. Receivers demodulate only the sub-group of subcarriers in which they are to receive data.

This saves energy which is important for battery powered devices. A transform bandwidth smaller than the transform bandwidth of the transmitter is used that encompasses the receivers pass band, plus the 2 transition bands (upper and lower) of the linear filter. This technique maintains orthogonality between subcarriers. The subcarriers in the pass band are utilized and the subcarriers in the transition bands are discarded. The orthogonal subcarriers may include both orthogonal frequency division multiplexed and pulse amplitude modulated signals. A notch filter may be included in the receiver to remove unwanted non-orthogonal signals such as a television signal or other interference. |
