Abstract
A device, method and system is directed to fast data storage on a block storage device. New data is linearly written to an empty write block. A location of the new data is tracked. Meta data associated with the new data is linearly written. A lookup table may be updated based in part on the meta data. The new data may be read based the lookup table configured to map a logical address to a physical address.
Claims19
A method of fast data storage on a block storage device, the method comprising the steps of:
- linearly writing new data to an empty write block;
- tracking a location of the new data;
- linearly writing meta data associated with the new data;
- and
- unmounting the device, including writing to each write block of the device and writing meta data associated with said each write block.
A block storage device for optimizing data access comprising:
- a mapping layer configured to dynamically remap data;
- and
- a plurality of data blocks, each data block storing map information,
- wherein each cluster of data blocks stores meta information, including an age of the data blocks of the cluster, a count of the data blocks of the cluster, and an array of logical block numbers for the data blocks of the cluster data;
- and
- wherein unmounting the device includes writing to each said data block and writing respective meta data associated therewith.
A system for fast data storage on a block storage device, comprising:
- the block storage device configured to perform actions comprising:
- linearly writing new data to an empty write block;
- tracking the location of the new data;
- linearly writing meta data associated with the new data;
- and
- unmounting the device, including writing to each write block of the device and writing meta data associated with said each write block.
A method of fast data storage on a block storage device, the method comprising the steps of:
- linearly writing at least one portion of meta-information associated with a plurality of write blocks;
- getting an empty write block for writing the new data, if a current write position is at an end of the plurality of write blocks;
- linearly writing new data in one of the empty write block or one of the plurality of write blocks;
- updating a lookup table based on an address where the new data is written to;
- and
- unmounting the device, including writing to each write block of the device and writing meta data associated with the each write block.
A block storage device for optimizing data access and update patterns comprising:
- a segment of known data in logical and linear order;
- a further segment of free space for the acceptance of updates;
- and
- a logical area for storing update reference changes,
- wherein unmounting the device includes writing to each segment of the device and writing meta data associated with each said segment.
A system for optimizing data access, comprising:
- a block storage device configured to perform actions comprising:
- linearly writing meta information and new data associated with a logical address to an empty write block;
- updating a lookup table based on an address of the empty write block and the logical address;
- reading the new data from a data storage based on the lookup table;
- and
- unmounting the device, including writing to each write block of the device and writing meta data associated with said each write block,
- the data storage configured to provide the empty write block.
