Abstract
Methods and systems to disperse and collate I/O from virtual machines (VMs) among a plurality of near line controllers for parallelization of I/O's (parallel reads and parallel writes) and for providing redundancy for stored VM data is disclosed.
Claims26
A method, comprising:
- configuring a non-transitory data storage medium to store a virtual aggregate including N nodes, where N is an integer that is ≧3, each node having a node block size;
- receiving data to be stored among the N nodes;
- parsing the data into M data blocks where M is an integer;
- performing a hashing function on each data block to generate metadata (MD) that is identical for each data block;
- selecting for each data block a selected node of the N nodes, and
- mirroring the MD in a metadata field of the selected node,
- mirroring a data payload of the data block in a mirrored data field of the selected node, and
- striping the data payload of the data block in a striped data field of one or more other nodes of the N nodes that are not the selected node;
- and
- repeating the selecting until the MD and data payloads of all the M data blocks have been mirrored and striped into at least a portion of the N nodes.
