摘要： Methods and structure are provided for enhancing zone configuration processes in a Serial Attached SCSI (SAS) architecture. The method includes embedding, at a SAS initiator, a ZONE UNLOCK request within a Serial Management Protocol (SMP) ZONE ACTIVATE command. The method also comprises transmitting the SMP ZONE ACTIVATE command to a SAS expander, and receiving, at the SAS expander, the SMP ZONE ACTIVATE command. Further, the method includes detecting, at the SAS expander, the ZONE UNLOCK request within the SMP ZONE ACTIVATE COMMAND. Additionally, the method includes copying, at the SAS expander, shadow SAS zoning data from a memory of the expander to current SAS zoning data at the memory of the expander responsive to acquiring the SMP ZONE ACTIVATE command. The method also comprises unlocking the SAS expander responsive to extracting the ZONE UNLOCK request from the SMP ZONE ACTIVATE command.

摘要： A method and system for protection switching distributes responsibility for action between a central controller and network elements at endpoints of a linear point-to-point network path. The central controller may be configured to support protection switching by network elements at endpoints of a linear point-to-point path, such that the network elements perform protection switching independently and without direct involvement and/or dependency of the central controller. Simultaneously, the central controller may remain aware of network element actions, events, and states with regard to protection switching, by receiving corresponding notifications from the network elements.

摘要： An apparatus and method for a power-efficient framework to maintain data synchronization of a mobile personal computer (MPC) are described. In one embodiment, the method includes the detection of a data synchronization wakeup event while the MPC is operating according to a sleep state. Subsequent to wakeup event, at least one system resource is disabled to provide a minimum number of system resources required to re-establish a network connection. In one embodiment, user data from a network server is synchronized on the MPC without user intervention; the mobile platform system resumes operation according to the sleep state. In one embodiment, a wakeup alarm is programmed according to a user history profile regarding received e-mails. In a further embodiment, data synchronizing involves disabling a display, and throttling the system processor to operate at a reduced frequency. Other embodiments are described and claimed.

摘要： The write-combining buffer combines data from separate data write operations into cache-line-sized buffer units for uncacheable types of data, such as frame buffer data. The write-combining buffer is implemented within a microprocessor having a data cache unit storing cacheable data within cache-lines. The data cache unit includes components and circuitry provided for efficiently inputting and outputting cache-line-sized units of data. By combining many uncacheable data write operations within a single cache-line-sized buffer, the circuitry and techniques employed for processing cache-lines are exploited in the processing of uncacheable data as well. A particular implementation is described wherein uncacheable data units corresponding to graphics write operations within an out-of-order microprocessor are combined into cache-line-sized buffers, then transmitted to a frame buffer using a burst mode eviction. Processor ordering requirements are ignored and global observability is relaxed for the graphics write operations. If the cache line sized buffer is not full when evicted, then a sequence of one or more burst-mode partial writes are employed to evict all data within the cache line sized buffer. If partial writes are employed, no delay between the partial writes is required.
摘要翻译：写组合缓冲器将来自单独数据写入操作的数据组合成用于不可缓存类型的数据（例如帧缓冲器数据）的高速缓存行大小的缓冲器单元。写组合缓冲器在具有数据高速缓存单元的微处理器内实现，该缓存单元在高速缓存行中存储可缓存数据。数据高速缓存单元包括用于有效地输入和输出高速缓存行大小的数据单元的组件和电路。通过在单个高速缓存行大小的缓冲器中组合许多不可缓存的数据写操作，用于处理高速缓存行的电路和技术也用于处理不可缓存的数据。描述了特定实现，其中对应于无序微处理器内的图形写入操作的不可缓存的数据单元组合成高速缓存行大小的缓冲器，然后使用突发模式驱逐发送到帧缓冲器。处理器排序要求被忽略，并且图形写入操作放宽了全局可观察性。如果缓存行大小的缓冲区在被驱逐时不满，则采用一个或多个突发模式部分写入的序列来驱逐高速缓存行大小的缓冲区内的所有数据。如果采用部分写入，则不需要部分写入之间的延迟。

摘要： A method and system for priority based (1:1)n Ethernet protection. The method and system includes assigning a priority to each of the flows associated with a working path. Upon fail of one or more of the working paths checking available bandwidth and priority of the flows. Once the request is complete, switching one or more flows to the protection path based on at least the priority of the flow, the bandwidth of the working path and the available bandwidth on the protection path. If a newly failed working path has a higher priority flow then dropping a flow from the protection path to a pending state. Once a working path has recovered, reverting the flow back to the working path and possibly admitting pending data to the protection path if the bandwidth and prioritization requirements are met.
