A method for storing data blocks within a volume of data is disclosed. The method involves creating a frame header to identify encoding and a size of a data block, storing the frame header and the data block in the volume of data, and creating an identifying sequence to identify if a data block is encoded or unencoded and storing the data block with the identifying sequence and with a frame header if the data block is encoded and storing the data block without the identifying sequence and without a frame header if the data block is unencoded.

System and method for storing data blocks in a volume of data

Methods and systems for handling requests for data corresponding to a volume of data are disclosed. A method involves generating meta data corresponding to a volume of data, the meta data including a set of range status registers, wherein each range status register corresponds to a unique range of memory in the volume of data, wherein the state of a range status register indicates whether or not data has been persisted within the range of memory that corresponds to the range status register and processing a request for a retrieve operation from the volume of data or for a persist operation to the volume of data as a function of a range status register in the meta data that corresponds to the request.

System and method for managing volumes of data in a block storage system

A method for performing cryptography operations on data blocks within a volume of data is disclosed. The method involves generating a volume master key, generating a user key, generating a volume initialization vector, generating an intermediate key, generating a user volume key, and performing cryptography operations on data blocks within an individual volume of data using the volume master key, the user key, the volume initialization vector, the intermediate key, and the user volume key.

System and method for implementing cryptography in a storage system

A method for provisioning a volume of data is disclosed. The method involves identifying a set of rules associated with the volume of data, wherein the set of rules includes at least two conflicting rules, prioritizing the at least two conflicting rules, and placing the volume of data on a first computer system according to the prioritization. The method also includes collecting performance metrics corresponding to the placed volume of data, computing a score based on the collected performance metrics, determining if the computed score is acceptable, and determining that the placement is successful when the computer score is determined to be acceptable. The method further includes changing the prioritization of the at least two conflicting rules and placing the volume of data on a second computer system according to the changed prioritization when the score is determined to be unacceptable. The volume of data may be placed on the second computer system only during hours when the second computer system is not used, or during a period of time in which activity on the second computer system is relatively low.

Method for provisioning a volume of data including placing data based on rules associated with the volume

A methods and systems for handling requests for data corresponding to a volume of data are disclosed. A method involves receiving a request from an application, the request related to retrieving a chunk of data from a volume of data or persisting a chunk of data to the volume of data, the request comprising an offset and a size of the chunk of data, establishing a short condition register for the chunk of data as a function of the offset and the size, establishing a long condition register for the chunk of data as a function of the offset and the size, and performing a retrieve operation from the volume of data or a persist operation to the volume of data as a function of the short condition register and the long condition register.
