Abstract: A computer system and method is disclosed for storing large volumes of event data. The system receives access event logs including indications of access events to files stored on a set of storage devices. Each indication includes respective values for a plurality of access event attributes. The system uses the indications to store multiple segment files, each corresponding to a respective subset of the indications. Each segment file stores data as multiple tiles, where each tile includes a compressed copy of those access event indications of the segment file that have a shared value for one of the access event attributes. Each tile is stored contiguously within a set of storage devices.

Abstract: A system for connection failover using redirection includes a primary server comprising a primary connection failover driver (CFD), a shadow server comprising a shadow CFD, and a client. The primary and shadow servers and the client are coupled via a network. The primary server and the client are configured to cooperate to establish a network connection. The primary CFD is configured to redirect a first message packet, targeted for transmission to the client over the network connection, to the shadow server. The shadow CFD is configured to copy contents of the first message packet into a log, and forward the first message packet to the client after the contents have been copied.
