Abstract: Systems and methods are disclosed which facilitate management of thin provisioned data storage. Specifically, portions of thinly provisioned data stores may be deallocated when they contain invalid data, such as data deleted by a user. A user may transmit notifications, which may include delete notifications, such as TRIM commands, to a provider of the data store (or to the data store itself) that data has been deleted. A management component may modify the data store, or metadata corresponding to the data store, to reflect the deletion. The management component may further monitor portions of the data store to determine whether individual portions contain entirely invalid data. If so, the portion may be deallocated from the thin provisioned data store, resulting in more efficient thin provisioning. Deallocation may be enabled even where deletion notifications from a user do not correspond directly to allocated storage portions.

Abstract: Processes and systems are disclosed for leasing a producer virtual machine on behalf of a consumer virtual machine in an overlay network. The consumer host of the consumer virtual machine can communicate with a set of leasing agents to obtain the identity of a number of producer virtual machines capable of providing the consumer virtual machine with access to a service. When the consumer virtual machine attempts to communicate with a producer system, the consumer host can identify a producer host that hosts a target producer virtual machine and redirect a service request to the producer host.

Abstract: The state of firmware for devices on a provisioned host machine can be validated independent of the host CPU(s) or other components exposed to the user. A port that is not fully exposed or accessible to the user can be used to perform a validation process on firmware without accessing a CPU of the host device. The firmware can be scanned and a hashing or similar algorithm can be used to determine validation information, such as hash values, for the firmware, which can be compared to validation information stored in a secure location. If the current and stored validation information do not match, one or more remedial actions can be taken to address the firmware being in an unknown or unintended state.

Abstract: High-speed processing of packets to, and from, a virtualization environment can be provided while utilizing segmentation offload and other such functionality of commodity hardware. Virtualization information can be added to extension portions of protocol headers, for example, such that the payload portion is unchanged and, when physical address information is added to a frame, a frame can be processed using commodity hardware. In some embodiments, the virtualization information can be hashed and added to the payload or stream at, or relative to, various segmentation boundaries, such that the virtualization or additional header information will only be added to a subset of the packets once segmented, thereby reducing the necessary overhead. Further, the hashing of the information can allow for reconstruction of the virtualization information upon desegmentation even in the event of packet loss.

Abstract: Methods and apparatus for supporting cached volumes at storage gateways are disclosed. A storage gateway appliance is configured to cache at least a portion of a storage object of a remote storage service at local storage devices. In response to a client's write request, directed to at least a portion of a data chunk of the storage object, the appliance stores a data modification indicated in the write request at a storage device, and asynchronously uploads the modification to the storage service. In response to a client's read request, directed to a different portion of the data chunk, the appliance downloads the requested data from the storage service to the storage device, and provides the requested data to the client.

Abstract: High-speed processing of packets to, and from, a virtualization environment can be provided while utilizing hardware-based segmentation offload and other such functionality. A hardware vendor such as a network interface card (NIC) manufacturer can enable the hardware to support open and proprietary stateless tunneling in conjunction with a protocol such as single root I/O virtualization (SR-IOV) in order to implement a virtualized overlay network. The hardware can utilize various rules, for example, that can be used by the NIC to perform certain actions, such as to encapsulate egress packets and decapsulate packets.

Abstract: A virtual tape is constructed using a logical data container to aid in emulating a virtual tape by providing tape functionality, reducing seek time and improving recovery time in case of a failure. For example, the logical data container may comprise a global header followed by one or more data block groups. The global header may provide metadata to track record locations, file mark locations, virtual tape data in memory, data validation information and a virtual tape head location. This metadata in the global tape header may help reduce seek time, improve recovery time using last known data in memory, erase a virtual tape and provide tape head position. Data block groups may include information that validates data, provides error correction, provides record and file marks and provides storage of client data.

Abstract: A virtual tape library system is used to back up data from a client archive system expecting physical tape operations onto logical data containers and/or a metadata store of a storage service by emulating the physical tape operations. For example, a virtual tape library appliance is installed at a customer premise location to interface with a client archive system. The virtual tape library appliance provides virtual interfaces to appear as physical tape library subsystems, such as tape drives and media changing interfaces. However, these virtual interfaces are supported by logical data containers in a storage service and a metadata store. The virtual tape library system allows the client archive system to make requests to import new virtual tapes, export virtual tapes for archiving, store virtual tapes at a virtual location, load and eject virtual tapes into a virtual tape drive and operate on virtual tapes in a virtual tape drive.
