Some embodiments provide a hierarchical data service (HDS) that manages many resource clusters that are in a resource cluster hierarchy. In some embodiments, each resource cluster has its own cluster manager, and the cluster managers are in a cluster manager hierarchy that mimics the hierarchy of the resource clusters. In some embodiments, both the resource cluster hierarchy and the cluster manager hierarchy are tree structures, e.g., a directed acyclic graph (DAG) structure that has one root node with multiple other nodes in a hierarchy, with each other node having only one parent node and one or more possible child nodes.

Some embodiments provide a method of providing distributed storage services to a host computer from a network interface card (NIC) of the host computer. At the NIC, the method accesses a set of one or more external storages operating outside of the host computer through a shared port of the NIC that is not only used to access the set of external storages but also for forwarding packets not related to an external storage. In some embodiments, the method accesses the external storage set by using a network fabric storage driver that employs a network fabric storage protocol to access the external storage set. The method presents the external storage as a local storage of the host computer to a set of programs executing on the host computer. In some embodiments, the method presents the local storage by using a storage emulation layer on the NIC to create a local storage construct that presents the set of external storages as a local storage of the host computer.

The present disclosure relates to device in a network. The device includes an obtaining module, a storage module, and a determination module. The obtaining module is configured to obtain topology information associated with one or more nodes available in a network. The storage module is configured to store the topology information obtained along with meta-information associated with the topology information, if any. The determination module is configured to determine placement of at least storage resources on at least one node selected from the one or more nodes based on the topology information and the meta-information.

A fault-tolerant configuration to share computer accessible data storage devices contained in a computer system with other such computer systems. Embodiments of the present invention allow sharing data storage devices contained in a first computer storage system with a second computer system by providing two or more independent connections to the data storage devices, such connections to the second computer system being independent of a motherboard (or a component thereon) contained in the first computer system, and thus ensuring continued access to the storage devices in the presence of component failures of the first computer system, such components being redundant.

A fault-tolerant and efficient way of deducing a set of inconsistent stripes for a network RAID protocol, wherein clients forward input/output (I/O) to a particular controller device called the coordinator, which executes RAID logic and which sends out device IOs to the relevant storage devices. If the coordinator fails then a new coordinator reconstructs its state from the storage devices.

A three-dimensional computer infrastructure cooling system is provided. The three-dimensional computer infrastructure cooling system includes at least one compute, storage, or communications brick. In addition, the three-dimensional computer infrastructure cooling system includes at least one coldrail to facilitate the removal of heat from the at least one compute, storage, or communications brick. Also, the three-dimensional computer infrastructure includes a brick-internal carrier within the at least one compute, storage, communications brick, wherein the brick-internal carrier is attached to the at least one coldrail. Moreover, the three-dimensional computer infrastructure includes a power dissipating electronic element within the at-least-one compute, storage, or communications brick, wherein the power dissipating element is attached to the brick-internal carrier.

A client node of a distributed storage system adaptive determines on an operation-by-operation basis whether to process a network-RAID IO operation (IO request) locally at the client node or to forward the IO request to a storage server of the system for processing. The client node determines to process the requested network-RAID operation at the client node when a local estimator for a type of the requested network-RAID operation is less than a central estimator for the type of the requested network-RAID operation. Otherwise, the client node determines to process the requested network-RAID operation at a storage server when the local estimator for the type of the requested network-RAID operation is greater than the central estimator for the type of the requested network-RAID operation.

A telephone session between a calling person and a called person uses a call-related information segment which has been prepared by the calling person to inform the called person of the calling person and the subject of the session. The call-related information is transmitted to the called person and outputted there by use of an output unit, alerting the called person of the nature of the telephone session without the called person entering into the telephone session.
