Abstract: Aspects of the present disclosure relate to transmitting prioritized path data to a device based on a set of topology rules and metrics associated with a storage target. A storage target path discovery request is received from the device. In response to the storage target path discovery request, metrics associated with the storage target are collected. Based on the collected metrics, available paths to the storage target are identified. A set of topology rules are then determined. Based on the topology rules and the collected metrics, a subset of available paths are selected. The subset of available paths are then prioritized into prioritized path data. The prioritized path data is then stored and transmitted to the device.

Abstract: A method and a system for execution of client-initiated operations on file handles in a distributed server system. The method may include: generating a file handle, responsive to a connect request sent by a client to a distributed file system, wherein the handle has a handle identifier that is unique throughout the distributed file system; embedding a protocol server identifier within the handle identifier, wherein the protocol server identifier relates to a protocol server to which the handle is assigned, wherein the protocol server is a data structure containing a list of all valid handles that belong to a specific file; sending an operation request from said client to the distributed file system, wherein the file system operation request includes the handle identifier; and locating the protocol server based on the protocol server identifier embedded within the handle identifier upon receiving the operation request at the distributed file system.

Abstract: A method and a system for reconnecting Server Message Block (SMB) clients to file handles. The method may include: generating a file handle, wherein the handle has a handle identifier and further associated with at least one data key other than the file name; embedding a protocol server identifier within the handle identifier, wherein the protocol server identifier relates to a protocol server to which the handle is assigned, wherein the protocol server is a data structure containing a list of all valid handles that belong to a specific file; sending an operation request from the client to the distributed file system, wherein the file system operation request includes the handle identifier and the at least one data key; locating the protocol server based on the protocol server identifier, upon receiving the operation request at the distributed file system; and validating the data key for executing the operation request.

Abstract: A method and a system for execution of disconnection from and reconnection to persistent handles are provided herein. The method may include the following steps: generating a file handle, responsive to a file connect request sent by a client to a distributed file system, wherein the handle has a handle identifier; associating a reconnect identifier with the handle identifier, wherein the reconnect identifier is indicative of a most recent connect attempt made using the respective handle identifier at a respective request; sending a disconnect request responsive to a disconnection, wherein the disconnect request is sent with a reconnect identifier indicative of a connection prior to the disconnection; updating the reconnect identifier, responsive to a reconnect request associated with said handle identifier; and approving the disconnect request only in a case that the reconnect identifier of the disconnect request is identical to the reconnect identifier of the reconnect request.
