Techniques described herein relate to systems and methods of data storage, and more particularly to providing layering of file system functionality on an object interface. In certain embodiments, file system functionality may be layered on cloud object interfaces to provide cloud-based storage while allowing for functionality expected from a legacy applications. For instance, POSIX interfaces and semantics may be layered on cloud-based storage, while providing access to data in a manner consistent with file-based access with data organization in name hierarchies. Various embodiments also may provide for memory mapping of data so that memory map changes are reflected in persistent storage while ensuring consistency between memory map changes and writes. For example, by transforming a ZFS file system disk-based storage into ZFS cloud-based storage, the ZFS file system gains the elastic nature of cloud storage.

Utilities (e.g., methods, systems, apparatuses, etc.) for use in automatically identifying improper physical connections in storage networks and recommending particular actions (e.g., changes to existing physical connections) that seek to ensure symmetric and redundant connections from a data host through all associated storage enclosures and reduce the likelihood that single failures prevent access to storage system data.

Redundant cable routing management in storage systems

In a network monitoring system, a plug-in module specifies how devices of that type should be discovered, including the directories or registries that should be examined for device references, how these directories should be examined, how the network should be probed for devices and how detected devices should be identified. Each plug-in module has one of a plurality of predetermined standard interfaces that allow the discovery modules to operate with a single discovery framework. During a discovery operation for a particular device type, the discovery framework dynamically creates the discovery plug-in modules necessary to discover devices of that type and controls these modules via the standard interfaces to perform device type specific discovery.
