Abstract: A computer-implemented method for effectively delivering notifications in data storage environments includes, receiving, by a storage controller from a host system, a request to register the host system with the storage controller to receive notifications. These notifications may be associated with a selected type of event detected by the storage controller. In certain embodiments, the selected type of event is a space-related condition associated with a particular storage resource controlled by the storage controller. The computer-implemented method registers the host system with the storage controller. In response to detecting an event of the selected type on the storage controller, the computer-implemented method transmits a notification from the storage controller to the host system to provide notice of the event. A corresponding system and computer program product are also disclosed.

Abstract: A device for cutting pipe includes support structure for contacting a pipe to be cut; an elongate cutting member associated with the support structure defining a loop for enclosing a pipe to be cut; and guide structure for reciprocally guiding the cutting member along a path relative to the support structure, whereby reciprocating the cutting member cuts the pipe.
