Abstract: Apparatus and computer program product for enabling an error strategy in a storage system with an initiator and a plurality of storage devices connected by a network, such as a storage area network (SAN). The computer program product is operable for recording timing statistics for transactions between an initiator and a target storage device; analyzing the recorded timing statistics for a target storage device; and applying the statistical analysis for a target storage device to error recovery procedures for the target storage device. The computer program product may also record statistics for transactions between an initiator and a target storage device using a particular network route. The recorded and analyzed timing statistics can be used to provide a dynamic error strategy based on the performance of individual target devices and routes.

Abstract: A high efficiency fan and stator arrangement for generating an airflow through a heat exchanger is disclosed herein. The fan is rotated about its rotational axis by an electric motor, and includes eight blades extending radially from a hub to a circular band. Each fan blade has a stagger angle and chord lengths which vary along the span of the blades. Each fan blade also includes a trailing edge having a flat surface extending along the edge. The flat surfaces of each fan blade are coincident with a plane perpendicular to the rotational axis. The fan produces an airflow when rotated about the rotational axis, wherein a component of the airflow occurs at a first angle to the rotational axis. The fan support has a central bearing support and twenty elongated airfoils extending radially outward from the bearing support. Each airfoil has substantially the same length as the fan blades and includes a curved airflow guiding surface having a leading edge and a trailing edge downstream from the leading edge.
