According to one embodiment of the present disclosure, a first set of file system objects included in performing the requested file system operation is identified in response to a request to perform a file system operation. An update intent corresponding to the requested file system operation is inserted into an inode associated with each identified file system object. Each file system object corresponding to the inode is modified as specified by the update intent in that inode. After modifying the file system object corresponding to the inode, the update intent is removed from that inode.“

Tier-optimized write scheme
Cohesity, Inc., Santa Clara, CA, has been assigned a patent (9,696,913) developed by Aron, Mohit, Los Altos, CA, and Shanmuganathan, Ganesha, Santa Clara, CA, for a “tier-optimized write scheme.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Techniques are disclosed for storing data in a plurality of storage tiers on a computing node. A node receives a request to write data corresponding to at least a first portion of a file. The node determines whether to perform the request either as an in-place write or as an out-of-place write. Upon determining to perform the request as the in-place write, the node writes the data to a first location on a storage tier which currently stores the first portion of the file. Upon determining to perform the request as the out-of-place write, the node writes the data to a second location on one of the storage tiers, other than the first location.“

The patent application was filed on April 13, 2015 (14/684,536).
