摘要:
A technique provides secure access to a set of credentials within a data storage system. The technique involves obtaining a unique identifier (e.g., a hostname which is unique to the system) and a set of stable values (e.g., machine-generated codes which are random to users of the system); and, in response to a storage request from a client application, storing a set of credentials of the client application within a data security mechanism of the data storage system. The set of credentials is in encrypted form when stored within the data security mechanism of the data storage system. The technique further involves configuring the data security mechanism of the data storage system to provide the set of credentials in non-encrypted form in response to new fingerprints matching a system fingerprint which is formed at least in part from the unique identifier and the set of stable values.

A method is used in mapping data storage and virtual machines. A logical volume from a data storage system is provided for use by a hypervisor. The hypervisor is queried through a web service to identify a virtual machine of the hypervisor. It is determined that the virtual machine is using the logical volume.

A method is used in managing virtual systems in data storage systems. First and second virtual systems are managed. The first virtual system uses a first format for communicating with a data storage system and the second virtual system uses a second format for communicating with the data storage system. A universal virtual system management module of the data storage system is used for communicating with the first and second virtual systems. The universal virtual system management module communicates with the first virtual system by using a first virtual system handler configured to communicate based on the first format. The universal virtual system management module communicates with the second virtual system by using a second virtual system handler configured to communicate based on the second format.

Subject matter includes exemplary systems and related methods for fully scalable encryption of scalable multimedia. A scalable bitstream encrypted using the subject matter maintains full functionality of scalable features in the encrypted form. The exemplary scalable encryption allows transcoding, rate shaping, and other operations directly on the ciphertext without degradation of scalable compression efficiency and error resiliency.

A safety angle cock air-bleeding in a multi-mode and having a ball core revolved in a single direction is of switch valves used in a train air brake system. The safety angle cock includes a cock body with a casing, a shaft, a main pipe joint and a hose joint with a locking nose, wherein there is on a upper part of the casing of the cock body a limit stop with a handle mount, a pallet and a ratchet wheel are disposed in the handle mount for controlling rotation of the shaft in a single direction, a small sealing ring is arranged at a hose connection port of the cock body and a large sealing ring at a main pipe connection port of the cock body, and a ball core positioned in the cock body is connected to the lower end of the shaft and provided with a air bleeding slot on each side thereof, the length of the slot being bigger than the diameter of the small sealing ring and smaller than the diameter of the big sealing ring, characterized in that an air bleeding valve for adjusting and controlling air-bleed is mounted at a bottom of the casing of the cock body. The invention adopts multi-level automatic protection technology and can thereby achieve such favorable effects as guaranteeing the safe of train, improving the safe operation level, ameliorating the operating mode, freeing the product from regular maintenance, and lowering the production and application cost.

A UMTS extension to the GSM/GPRS RIL is disclosed. The UTMS RIL provides an API set interface for the support of UMTS features such as 3G QoS, secondary PDP contexts call, priority service, voice group call and voice broadcast services, etc. The API set is based on the UMTS AT command interface as defined in 3GPP specification TS 27.007. The architecture of the UMTS RIL is designed as a standard interface with APIs and callback mechanisms that can be used across different platforms and multi-radio hardware such as GSM, GPRS, WCDMA, and HSDPA. The UTMS RIL may enable various applications running on mobile platforms in 2G, 2.5G, and 3G cellular radio stacks to issue commands without knowledge of underlying radio hardware structure.
摘要:
Described are techniques for configuring storage access control. A set of inputs including a first identifier of an initiator port and a device set devices in a data storage system is received. Responsive to receiving the set of inputs, an allowable path set is automatically defined for the initiator in accordance with an initiator-level of granularity. Each device in the device set is accessible by the initiator over each path in the allowable path set. The allowable path set includes paths between the initiator port and each target port of the data storage system. A set of target ports is either specified using a wildcard indicator denoting all target ports of the data storage system, or the set of target ports is otherwise determined implicitly as all target ports of the data storage system.
