摘要： A method and system for generating parity symbols and rebuilding data symbols in a RAID system. The method includes receiving a command to generate a desired parity or data symbol using an XOR relationship between some of a plurality of parity and data symbols. A symbol of the plurality of parity and data symbols is input to an XOR accumulator, the symbol being included in the XOR relationship. Additional symbols of the plurality of parity and data symbols are input to the XOR accumulator. Each time that an additional symbol is input and is included in the XOR relationship, an XOR operation is performed between the symbol in the XOR accumulator and the additional symbol, thus obtaining a resulting symbol that replaces the previous symbol in the XOR accumulator. After every symbol included in the XOR relationship has undergone an XOR operation, the symbol in the XOR accumulator is output as the desired parity or data symbol.

摘要： A dual parity hardware architecture that enables data to be read from each sector only once and performs both the P parity and Q parity from the single data source. The Q parity calculator provides parallel processing capabilities so that multiple parity operations are performed on the same sector simultaneously. The dual parity hardware architecture provides flexibility in restoring data, generating parity, and updating parity for differing data sector sizes.

摘要： A system for mapping between logical addresses and storage units of a plurality of storage volumes which comprise a storage system. For each volume, logical addresses are mapped to storage units using a volume mapping table. Each volume mapping table is comprised of a plurality of segments. Each segment need not be contiguously allocated to another segment of the same table. Thus, each volume mapping table can be independently expanded or reduced without affecting other volume mapping tables. A hash function, a hash table, a segment table, and a redundancy group descriptor table may also be used to help manage the segments of the volume mapping tables.
摘要翻译：用于在包括存储系统的多个存储卷的逻辑地址和存储单元之间进行映射的系统。对于每个卷，使用卷映射表将逻辑地址映射到存储单元。每个卷映射表由多个段组成。每个段不需要连续地分配给同一个表的另一个段。因此，可以独立地扩展或缩小每个卷映射表，而不影响其他卷映射表。散列函数，哈希表，段表和冗余组描述符表也可以用于帮助管理卷映射表的段。

摘要： A system, method and apparatus for determining a support entitlement level are provided. A product support request is received from a customer. A technical support identification (TSID) is also received from the customer. The TSID is validated and classified. The TSID may be classified into at least one of several classifications. One of the classifications is a contract classification. At least one of several support levels are assigned to the classified TSID. The assigned support level corresponds to the TSID classification. The TSID is received, validated, classified and the support level assigned before a product support agent is notified of the product support request. Then the assigned support level is delivered.

摘要： A two-dimensional command block queue includes a plurality of command blocks in a first linked list. One of the command blocks in a string is included in the first linked list. The string is delimited by only a tail pointer stored in a tail pointer list. Following dequeuing the string for processing, a pointer to the one command block of the string that was in the common queue is included in a string head pointer list. The tail pointer to the string is not changed in the tail pointer list following dequeuing of the string. This allows any new SCBs to be appended to the end of the string, while the string is being processed. This allows streaming of new SCBs to an I/O device that had previously been selected and is still connected to the host adapter.
摘要翻译：二维命令块队列包括第一链表中的多个命令块。字符串中的一个命令块包含在第一个链表中。字符串仅由尾部指针列表中存储的尾部指针分隔。在列出要处理的字符串之后，指向公共队列中的字符串的一个命令块的指针包含在字符串头指针列表中。在字符串出列之后，尾部指针列表中没有改变字符串的尾部指针。这样可以在处理字符串时，将任何新的SCB追加到字符串的末尾。这允许将新的SCB流传输到先前已被选择并仍连接到主机适配器的I / O设备。

摘要： An invention is provided for data bit align. The invention includes a multiplexer that receives a data sample word as data input and also receives a clock sample word as select input. The multiplexer selects a data bit from the data sample word based on the clock sample word. Generally, the multiplexer can select the data bit from the data sample word corresponding to a position of the clock edge in the clock sample word. The invention also includes an output register, which is coupled to the multiplexer. The output register stores the selected data bit from the multiplexer and provides the selected data bit to remaining system components.

摘要： An apparatus for performing a boundary scan test is provided, along with method for integrating and operating the same. The apparatus includes an asynchronous flip-flop that has a data input, a data output, a system clock input, a set input, and a reset input. The apparatus also includes a test controller that has a test clock input, a first test data output, and a second test data output. The first test data output of the test controller is connected to the set input of the asynchronous flip-flop. In addition, the second test data output of the test controller is connected to the reset input of the asynchronous flip-flop. The test controller is configured to control the asynchronous flip-flop through the set input and the reset input. The apparatus for performing the boundary scan test avoids introduction of adverse delay and skew effects caused by multiplexing circuitry.
