SYSTEM AND METHOD FOR MANAGING VOLUMES OF DATA IN A BLOCK STORAGE SYSTEM
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.
1 . A method for handling requests for data corresponding to a volume of data, the method comprising:
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;
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.
