Abstract: A flow diverter device is used to redirect the blood flow inside the cerebral blood vessels and for the reduction of blood flow to the aneurysm, hence preventing the chance of aneurysm rupture as well as promoting the healing of the aneurysm. The novel design of the device, using a set of thicker wires, provides high kink resistance and radial strength. Two patterns of inter-braiding the thicker set of wires with the finer braid are disclosed, one having a checker-board and the other a ring structure. Both patterns are highly kink resistant with the checker-board design providing minimal loss in flexibility, whereas the ring design provides greater radial strength. The device could be made of super elastic materials like Nitinol wires with the thicker set being radio opaque. The device is highly kink resistant and sufficiently flexible for use in vasculature with complex bends.

Abstract: A system and method for providing cloud virtualization (SV) is disclosed. According to one embodiment, a system includes a transactional cloud manager and a compute cluster connected to the transactional cloud manager. The compute cluster includes a system monitor and a control manager in a host. A virtual machine runs on the host, wherein the virtual machine has a VM system monitor and a VM control manager. The transactional cloud manager creates virtual machine clusters on the host.

Abstract: A system and method for providing storage virtualization (SV) is disclosed. According to one embodiment, a system includes a storage device having a tier 1 cache and a Tier 2 storage, an operating system and a file system having a Tier 0 memory cache that stores application data. The Tier 0 memory cache synchronizes the application data with the tier 1 cache and the Tier 2 storage.

Abstract: A method and system for dynamic storage scaling based on automatically parallelizing access of names and data across multiple nodes or micro object stores (MOSs) is provided. A dynamic storage scaling device cluster is provisioned for a particular level of parallelism (e.g., N MOSs) when the cluster is created. The N MOSs may initially reside in a few physical servers (e.g., one server). When the data distribution causes peak resource usage of the physical servers, new server(s) can be added. Some micro object stores (MOSs) are moved to the new physical server(s) through a meiosis process. The storage devices associated with the moved MOSs are unmounted from the original servers and mounted to the new server(s). The meiosis continues until the cluster grows to full capacity. The scaling is dynamic and efficient since no data copy is involved in the meiosis and the initial resource cost is optimized.

Abstract: A system and method for providing dynamic information virtualization (DIV) is disclosed. According to one embodiment, a device includes a dynamic optimization manager (DOM), a process and memory manager (PMM), a memory, and a host device driver. The device starts virtual functions after booting to allow a virtual machine (VM) running a guest operating system to identify the virtual functions and load virtual drivers of the virtual functions. The PMM allocates a unified cache from the memory to facilitate coherent access to information from storage and network resources by the VM. The host device driver enables a guess process in the VM to access the information stored in the unified cache in a secure and isolated manner.
