Abstract: A method for detecting asymmetric path delay changes in a synchronisation network comprises: monitoring a first path delay and a second path delay over a first sample period and a second sample period, wherein the first path delay is a reported time taken for a first packet transmitted by a first node of the network to be received by a second node of the network, and the second path delay is a time taken for a second packet transmitted by the second node of the network to be received by the first node of the network; determining that a change in one or both of the first and second path delays between the first sample period and the second sample period exceeds a first threshold; and determining whether the change in one or both of the first and second path delays is an asymmetric path delay change.

Abstract: Systems and methods are provided for backing up out-of-band storage. A protection policy is activated for out-of-band storage at a remote host, wherein the out-of-band storage is not physically accessible by the computing device, such that the out-of-band storage is not in communication with the remote host through the computing device. A backup request is transmitted to the remote host comprising data indicative of a volume on the out-of-band storage to back up according to the protection policy. A response to the backup request is received comprising staging disk requirements for the volume, the staging disk requirements comprising a required size for a staging disk to back up the volume. A staging disk is determined based on the response. The staging disk is presented to the remote host. A backup result is received comprising data indicative of whether a backup of the volume to the staging disk succeeded.

Abstract: Distributing and redistributing records among a changing set of storage devices is accomplished by grouping the records based on the starting and ending numbers of storage devices.

Abstract: Systems and methods for managing data within a networked computer environment including application servers and a plurality of storage devices utilize a collection of service modules, each separately addressable from and in communication with the application servers and the storage devices and providing system-wide services to the application servers and the storage devices.
