The location of resources for file services are located within the same site, thereby eliminating or reducing performance issues caused by cross-site accesses in a stretched cluster environment. A file server placement algorithm initially places file servers at a site based at least in part on host workload and affinity settings, and can perform failover to move the file servers to a different location (e.g., to a different host on the same site or to another site) in the event of a failure of the host where the file servers were initially placed. File servers may be co-located with clients at a location based on client latencies and site workload. Failover support is also provided in the event that the sites in the stretched cluster have different subnet addresses.

Site locality support for file services in a stretched cluster environment

Machine logic implemented techniques for preventing sending messages by mistake (with such 'mistakes' including sending a message to an unintended recipient). One embodiment of the technique includes: detecting an intention of sending a message to a target user; responsive to detection of the intention, predicting a risk that the target user is not a desired recipient of the message; and providing a prompt responsive to the predicted risk being higher than a predetermined threshold.
