20090089463 | Information Processing Device, Device Access Control Method, and Device Access Control Program - An information processing device, a device access control method, and a device access control program are provided. When a device built in or mounted on the information processing device is controlled, the OS manages access to the device driver, so as to restrict the use of the device. When issuing a control instruction to a device driver ( | 04-02-2009 |
20090144465 | Data processing apparatus and method of protecting a peripheral device in data processing apparatus - A data processing apparatus includes an arithmetic circuit and a peripheral device protection circuit that controls access of the arithmetic circuit to the peripheral devices. The peripheral device protection circuit has a first protection preset value and a second protection preset value set as a protection level higher than that of the first protection preset value. The peripheral device protection circuit includes: a setting selection circuit that generates access permission/denial information by referring to the first protection preset value and the second protection preset value when the arithmetic circuit operates at a first operation authority level, or by referring to the second protection preset value when the arithmetic circuit operates at the second operation authority level. An access protection circuit that determines permission/denial of access to the peripheral devices based on access information output from the arithmetic circuit and the access permission/denial information. | 06-04-2009 |
20100023657 | SYSTEM AND METHOD FOR SERIAL DATA COMMUNICATIONS BETWEEN HOST AND COMMUNICATIONS DEVICES, AND COMMUNICATIONS DEVICE EMPLOYED IN THE SYSTEM AND METHOD - A communications device includes a communications circuit, a memory, an identifier generator, and a latency controller. The communications circuit exchanges serial data with a host computer and a downstream device, and includes a first input, a first output, a second input, and a second output. The first input receives data from the host computer. The first output transmits data to the host computer. The second input receives data from the downstream device. The second output transmits data to the downstream device. The memory is accessible through the communications circuit. The identifier generator generates an identifier number unique to the communications device in response to an identifier setup request received at the first input. The latency controller determines, based on the generated identifier number, a period of latency required to access the memory through the communications circuit. | 01-28-2010 |
20100070662 | METHOD, APPARATUS AND SYSTEM FOR SERIAL ATTACHED SCSI (SAS) ZONING MANAGEMENT OF A DOMAIN USING INITIATOR ISOLATION - Embodiments of the invention include a method and apparatus for managing SAS zoning using initiator isolation. The method includes assigning initiator devices in the SAS domain to a first initiator zone group, assigning target devices in the SAS domain to a second target zone group, and establishing an access control policy in which each of the initiator devices assigned to the first initiator zone group can communicate with each of the target devices assigned to the second target zone group but no initiator devices assigned to the first initiator zone group can communicate with any other initiator devices assigned to the first initiator zone group. Assignment of devices can be based on attachment information associated with each device, such as the ZPSDS entry point of the device, the SAS address of the device, and the phy of the zoning expander device in the SAS domain that is closest to the device. | 03-18-2010 |
20110213904 | Storage apparatus and method of updating control information in storage apparatus - A storage apparatus | 09-01-2011 |
20110276728 | METHOD AND APPARATUS FOR STORAGE I/O PATH CONFIGURATION - An aspect of the invention is directed to a method for storage I/O (input/output) path configuration in a system that includes a storage system connected via a network to a plurality of nodes. The method comprises receiving an I/O access to one or more storage volumes in the storage system from one of the nodes; if the I/O access is an initial I/O access to any of the storage volumes in the storage system from any of the nodes in the system, allowing the initial I/O access from the one node and prohibiting I/O access to the storage volumes in the storage system by other nodes in the system; and if the I/O access is not an initial I/O access to any of the storage volumes in the storage system from any of the nodes in the system, allowing the I/O access only if the I/O access is from the one node which made the initial I/O access and rejecting the I/O access for other nodes in the system. | 11-10-2011 |
20140089538 | MANAGED ACCESS TO PERIPHERALS OF A SERVICE TERMINAL - Managed access to one or more peripherals of a service terminal is provided. A master controller controls access to the peripheral(s) by applications of the service terminal, wherein only a single application can access the peripheral(s) at a time, by identifying an application of the applications for placing into an on-focus state in order to enable access to the peripheral(s) by the identified application, and placing the identified application into the on-focus state, where access to the peripheral(s) by the identified application is enabled. The remaining applications of the applications execute in an off-focus state in which the master controller simulates, for the remaining applications, connectivity to the peripheral(s), and in which access to the peripheral(s) by the remaining applications is disabled transparent to the remaining applications while the access to the peripheral(s) by the identified application is enabled. | 03-27-2014 |
