摘要： A storage network control apparatus is operable to present virtualized storage to a host system and includes a monitoring component, an analysis component, a detection component, and a migration component. The monitoring component is for monitoring input/output (I/O) activity for virtual storage logical units over time. The analysis component is for identifying a repeating instance of peak I/O activity for a virtual storage logical unit over time and for generating a predictive signature therefrom. The detecting component is for identifying an instance of such a predictive signature. The migration component is responsive to the detecting component, and is for migrating data mapped by the virtual storage logical unit across additional real storage units to improve the I/O performance of the virtual storage logical unit prior to a recurrence of the repeating instance of peak I/O activity. A corresponding logic arrangement may be incorporated in hardware, software or a combination thereof.

摘要： A method for migrating data between heterogeneous data storage devices within a storage area network is disclosed. A first virtualizer presents stored data as a first virtual disk, and then communicates a managed disk representation of the first virtual disk to a second virtualizer. After receiving the managed disk representation, the second virtualizer virtualizes the stored data from the managed disk representation as a second virtual disk. At such point, the stored data can be progressively migrated from the first virtualizer to the second virtualizer.

摘要： Write requests from host computers are processed in relation to a thin provisioning storage subsystem. A write request is received from a host computer. The write request identifies a first virtual disk that has been previously assigned to the host computer. It is determined whether the first virtual disk has to be allocated additional physical storage locations of the thin provisioning storage subsystem for storing data associated with the write request. In response to determining that the virtual disk has to be allocated additional physical storage locations, the following is performed. First, a quantity of free space remaining unallocated within physical storage locations of the thin provisioning storage subsystem is determined. Second, where the quantity of free space remaining unallocated within the physical storage locations satisfies a policy threshold associated with a second virtual disk, the second virtual disk is write-inhibited. The first and second virtual disks can be different.

摘要： Mobile network services are performed in a mobile data network in a way that is transparent to most of the existing equipment in the mobile data network. The mobile data network includes a radio access network and a core network. A first service mechanism in the radio access network breaks out data coming from a basestation, and performs one or more mobile network services based on the broken out data. A second service mechanism in the core network performs one or more mobile network services based on the network traffic remaining after the first service mechanism performs its breakout. An optional third service mechanism coupled to the core network provides one or more mobile network services in the mobile data network. An overlay network allows the first, second and third service mechanisms to communicate with each other. The overlay network is preferably a private virtual network.

摘要： A mobile data network includes a radio access network and a core network. A first service mechanism in the radio access network breaks out data coming from a basestation. When data is broken out by the first service mechanism, the data is delivered at the edge, which means the true activity of the channel is not visible to the core network. The reduction of data in the core network due to serving data at the edge risks causing a switch from a high-speed channel to a low-speed channel by the mechanism in the core network that monitors and assigns channel speeds. In order to maintain the high-speed channel, the on-going data rate for a subscriber session is monitored and channel maintenance traffic is injected towards and from the radio network controller (in both directions). The amount of channel maintenance traffic depends on thresholds that determine a desired data rate.
