Abstract: A power aware data storage system comprises storage configured to store physical data files, the storage comprising several types of storage that are associated with different access times and power consumption; a storage authority coupled with the storage, the storage authority configured to control uploading of files to the storage, and downloading of files from the storage; web services configured to interface the storage authority with end users via the internet and to allow the end users to select the type of storage for each physical file or group of physical files; and a power consumption application configured to compute power consumption information for each physical data file stored in the storage and to report the power consumption information via the web services.

Abstract: A system can include: an online storage system; and a computer-readable medium having encoded thereon a computer program structured to interact with an electronic mail system and to provide a file-attachment interface that uploads a document to the online storage system in a separate process, and adds associated link information to an electronic mail message before completion of the separate process, in response to requested attachment of the document to the electronic mail message. A method can include: receiving information designating an electronic mail message currently being generated for an electronic mail system residing in a first domain; inserting, in response to the receiving, a file-attachment interface element into a user interface for the electronic mail message; and adding, in response to use of the file-attachment interface element, to the electronic mail message link information identifying a document stored in an online storage system residing in a second domain.
