摘要： The present invention is directed to a boot appliance for a data storage system. The boot appliance is a self-contained, pre-configured device that serves as a boot device for multiple servers. The boot appliance contains multiple hard drives which are configured into one or more RAID volumes. Each volume is divided into multiple partitions, with each partition serving as the boot drive for any server connected to it. The boot appliance provides its own environmental controls and Ethernet connection which may be used for providing alerts regarding the health of the components of the boot appliance and/or data storage system to a monitoring system, such as a network management system. The boot appliance may provide a boot drive and operating system image to multiple servers at the same time.

摘要： A memory management unit (MMU) for a device controller that provides enhanced functionality while maintaining a small physical size or footprint, such that the die size required to manufacture the memory management unit circuitry within the device controller integrated circuit device remains small notwithstanding such enhanced functionality. This compact/tiny MMU provides virtual memory addressing and memory error detection functionality while maintaining a small physical die size. The small physical die size with enhanced functionality is obtained by improvements in translating virtual to physical addressing without use of extensive translation tables, which themselves would otherwise consume memory and associated die real estate. In addition, the MMU allows a firmware image containing code and data segments to be run-time swapped between internal shared context RAM and external memory.

摘要： The present invention is directed to a method and system for efficient write journal entry management maintaining minimum write journal information stored in a nonvolatile memory through utilizing an additional structure in a fast volatile memory. The method and system may manage write journaling of a file volume including multiple fixed sized regions and assign a persistent 1-bit synchronization status (the write journal information) to each data region. In addition, a non-persistent I/O counter (the additional structure) for each region to manage the persistent 1-bit synchronization status during run-time. The present invention may provide a mechanism to determine when write I/O operations have not successfully completed to a specific region of the file volume.

摘要： Systems and methods for improving performance of a re-synchronization process in a RAID level 1 storage system. In one aspect a local cache memory associated with the second or mirrored disk drive is enabled during the re-synchronization operation but left disabled during normal operation processing host requests. The cache is flushed to the persistent medium of the second disk drive before resuming normal I/O request processing. In another aspect normal I/O request processing is interleaved with portions of the processing for re-synchronization of the mirrored disk drive. Normal I/O request processing proceeds for a first period of time. Re-synchronization processing for a portion of the mirrored information then proceeds (with local cache memory of the mirrored disk drive enabled) for a second period of time.

摘要： Methods and structure are disclosed for normalizing storage performance across a plurality of logical volumes. One embodiment is a storage controller. The storage controller is adapted to couple with a plurality of host systems and a storage device. The storage controller is adapted to receive one or more requests to create logical volumes for the plurality of hose systems, and adapted to identify a plurality of performance zones for storage areas of the storage device. The performance zones exhibit different performance criteria for one or more of: reading data from the storage device and writing data to the storage device. The storage controller is further adapted to allocate storage from each of the plurality of performance zones for each of the plurality of logical volumes such that the performance criteria for accessing the storage device is distributed substantially uniformly across the plurality of logical volumes.

摘要： Circuits and associated methods for testing internal operation of an application integrated circuit. Features and aspects hereof add configurable test interrupt circuits to an application circuit design to permit dynamic, configurable interrupt generation from an integrated circuit based on conditions determined from monitoring of internal signals of the application circuit. The internal signals that may be tested and used to generate test interrupts are those not exposed to the external processor interface of the integrated circuit and thus may be configured to interrupt based on any internal state of the application specific functional circuits of the integrated circuit.

摘要： An apparatus and method for dynamically enabling and disabling interrupt coalescing in a data processing system. The present invention involves consistently monitoring IO load on an IOP of an IO adapter. The firmware on the IO adapter may have a global variable that stores counters for PCI function registers. Each counter tracks the number of outstanding IOs of a corresponding PCI function register. The counter is incremented whenever a new IO is received and is decremented upon posting the completed message back to the OS. A timer interrupt is generated periodically so that an ISR may be periodically performed. In the ISR, the maximum value stored of each counter seen since last timer interrupt is analyzed. When the maximum value stored is greater than a predetermined threshold value, the interrupt coalescing is enabled.
摘要翻译：一种用于在数据处理系统中动态地启用和禁用中断合并的装置和方法。本发明涉及持续监视IO适配器的IOP上的IO负载。 IO适配器上的固件可能有一个全局变量，用于存储PCI功能寄存器的计数器。每个计数器跟踪相应PCI功能寄存器的未完成IO的数量。每当接收到新的IO时，计数器递增，并且在将完成的消息发回操作系统后递减。周期性地产生定时中断，以便周期性地执行ISR。在ISR中，分析从上一次定时器中断以来看到的每个计数器存储的最大值。当存储的最大值大于预定阈值时，中断合并被使能。
