Optimized path selection by non-latency detecting multipath hosts
Multipath hosts with the ability to detect path latency, report latency values on paths between the Latency Detecting (LD) host and a set of storage systems. The detected latency values are used by the storage system to create a data structure correlating path information with the detected latency values.

Device, method and system for controlling an access point based on movement trends of a mover
A device, method and system for controlling an access point based on movement trends of a mover is provided. A device receives images from a camera device, the camera device configured to image a region adjacent an access point, the access point initially in a first state that prevents access therethrough. The device identifies a designator of a mover in the images. The device determines, using the designator in the images, direction vectors of the mover. The device determines a trend of movement of the mover, relative to the access point, based on changes in one or more of slope and angle of the direction vectors of the mover. The device, in response to determining that the mover is trending towards the access point, changes the access point from the first state to a second state that provides access therethrough. |
