ReFS V2 Research Overview (Windows Server 2016)

We’re making a series of tests, dedicated solely to the work of Resilient File System (ReFS – https://msdn.microsoft.com/en-us/library/windows/desktop/hh848060%28v=vs.85%29.aspx). It is a relatively new proprietary file system, introduced by Microsoft in Windows Server 2012 as a successor of NTFS. Among its advantages over the predecessor, Microsoft lists enhanced protection from data corruption, common and silent alike, if provided with a redundant storage. The ReFS is also aimed at modern understanding of high capacity and large size. It supports files up to 16 million terabytes and maximum volume size (theoretical) of 1 trillion terabytes. The tests are associated with workloads typical for … Continue reading ReFS V2 Research Overview (Windows Server 2016)

Here’s what LSFS (WAFL, CASL) is About: Where Log-Structuring Concept Came From, What It’s Good for and Why

Log-Structured File System is a relatively new idea and the technology is obviously effective. However, it is a tool specially crafted for virtualization workload, thus it only works in certain cases. It won’t work out as a common file system for everyday tasks. The idea came from “transaction logs”, which aggregated small random writes into a log to copy them eventually to the “final destination”. Then ZIL (ZFS Intent Log) adopted the same principle in a file system.
