摘要： A method and apparatus for recovery from faults in a loop network (500) is provided. The loop network (500) has a plurality of ports (520, 530, 532, 534) serially connected with means for bypassing the ports (520, 530, 532, 534) from the loop network (500). A control device (522, 524) is provided with bypass control over at least one of the ports (530, 532, 534). A host means (502) sends a command to the control device (522, 524) at regular intervals and the control device (522, 524) has a counter which restarts a time period at the receipt of each command. If the time period expires, the control device (522, 524) activates the means for bypassing all the ports (530, 532, 534) under its control. The loop network (500) may have two loops (516, 518) with at least some of the ports (520, 530, 532, 534) common to both loops (516, 518).
摘要翻译：提供一种用于从循环网络（500）中的故障中恢复的方法和装置。环路网络（500）具有与环路网络（500）旁路端口（520,530,532,534）的装置串联连接的多个端口（520,530,532,534）。在至少一个端口（530,532,534）中，控制设备（522,524）被提供有旁路控制。主机装置（502）以规则的间隔向控制装置（522,524）发送命令，并且控制装置（522,524）具有在接收到每个命令时重新开始一段时间的计数器。如果时间段到期，则控制装置（522,524）激活旁路其控制下的所有端口（530,532,534）的装置。环路网络（500）可以具有两个环路（516,518），其中至少一些端口（520,530,532,534）对于两个环路（516,518）是公共的。

摘要： A method and apparatus for detection of a port name in a loop network is provided, particularly a loop network in the form of a Fibre Channel Arbitrated Loop (FC-AL). The loop network (100) has a plurality of devices (120) each device (120) having at least one port (211, 212) on the loop network (100). The method includes determining which ports (211, 212) are populated with devices (120) for which the unique port name (WWPN) is not known. The populated ports are then all bypassed and a mode is entered on the loop network (100) in which idle frames are transmitted around the loop network (100). One port is un-bypassed at a time and the port name from the un-bypassed port is received and recorded. The port name is received from the un-bypassed port in a Loop Initialisation Select Master (LISM) frame transmitted by the un-bypassed port.
摘要翻译：提供了用于检测环路网络中的端口名称的方法和装置，特别是以光纤通道仲裁环路（FC-AL）形式的环路网络。环路网络（100）具有多个设备（120），每个设备（120）在环路网络（100）上具有至少一个端口（211,212）。所述方法包括确定哪些端口（211,212）填充有唯一端口名称（WWPN）未知的设备（120）。填充的端口然后被旁路，并且在循环网络（100）上输入模式，其中空闲帧在环路网络（100）周围传输。一个端口一次未旁路，并且从未旁路端口的端口名称被接收和记录。在未旁路端口发送的循环初始化选择主站（LISM）帧中，从未旁路端口接收端口名称。

摘要： A method for migrating data between heterogeneous data storage devices within a storage area network is disclosed. A first virtualizer presents stored data as a first virtual disk, and then communicates a managed disk representation of the first virtual disk to a second virtualizer. After receiving the managed disk representation, the second virtualizer virtualizes the stored data from the managed disk representation as a second virtual disk. At such point, the stored data can be progressively migrated from the first virtualizer to the second virtualizer.

摘要： An arrangement and method for update of configuration cache data in a disk storage subsystem in which a cache memory (110) is updated using two-phase (220, 250) commit technique. This provides the advantage that known changes to the subsystem do not require an invalidate/rebuild style operation on the cache. This is especially important where a change will invalidate the entire cache.

摘要： A copy engine (104) is provided as an interface between firmware (108) and memory space (106) for carrying out copy operations. The copy engine has a first register (202, 203) to point to a first address and a second register (204, 205) to point to a second address. One of the first and second addresses is a source address and one is a destination address for data to be copied. The copy engine (104) also has a control register (201). The control register (201) includes a count of the amount of memory space required by a copy operation, an indication of the direction of the copy operation from the first address to the second address or from the second address to the first address, and an indication of whether the first memory address is incremented or decremented. The copy engine (104) includes a locking mechanism for locking the copy engine (104) during a copy operation. The copy engine (104) also includes a serialisation mechanism in which a write is made to the control register (201) of zero count. If the copy engine (104) is locked, the write of zero count is retried until the existing copy operation has completed and then it will complete with no effect.
摘要翻译：提供复制引擎（104）作为固件（108）和存储器空间（106）之间的接口，用于执行复制操作。复制引擎具有指向第一地址的第一寄存器（202,203）和指向第二地址的第二寄存器（204,205）。第一和第二地址之一是源地址，一个是要复制的数据的目的地址。复制引擎（104）还具有控制寄存器（201）。控制寄存器（201）包括由复制操作所需的存储空间量的计数，从第一地址到第二地址或从第二地址到第一地址的复制操作的方向的指示，以及指示第一个存储器地址是递增还是递减。复印机（104）包括用于在复印操作期间锁定复印机（104）的锁定机构。复制引擎（104）还包括序列化机制，其中对计数的控制寄存器（201）进行写入。如果复制引擎（104）被锁定，则重试零计数，直到现有的复制操作完成，然后它将不起作用。

摘要： A data storage subsystem includes a volatile memory in which stored data can be denoted as being data that should be preserved in the event of an interruption in the power supply to the volatile memory. The available capacity for such data storage is dynamically allocated between multiple firmware client components of the storage subsystem, such that each client component has its own (varying) allocation of the available capacity. A higher priority for the storage of such data is given to client components on which other client components depend, such as lower layers of the software stack, thereby allowing them to get a larger share of the available capacity for such data storage when needed and complete their input/output requests faster.

摘要： Systems and methods utilize inverse multiplexing to deliver a high bit rate service, such as streaming video, concurrently over multiple Asynchronous Digital Subscriber Lines (ADSL). Because ADSL delivery uses conventional telephone lines, and is relatively inexpensive, systems and methods of the present invention aggregate multiple ADSLs to deliver high bit rate service at a much lower cost than using more expensive, higher bit-rate lines, such as T-1 or T-3 lines. Additionally, because ADSL is highly asymmetric, the systems and methods are particularly suited to video delivery.
摘要翻译：系统和方法利用逆多路复用来通过多个异步数字用户线（ADSL）同时传送诸如流视频的高比特率服务。由于ADSL传输使用传统的电话线路并且相对便宜，所以本发明的系统和方法聚合多个ADSL以比使用更昂贵，更高比特率的线路（例如T-1）来低得多的成本提供高比特率服务或T-3线。另外，由于ADSL非常不对称，所以系统和方法特别适合于视频传送。
