    Abstract: A method and an apparatus is presented for configuring a system bus topology dynamically. In a preferred embodiment, the system bus is a Small Computer System Interface (SCSI) bus that connects a “daisy” chain of disk drives. Two types of disk drives are used: single ended (SE) “Ultra” drives capable of 20 MHz operation and LVD (low voltage differential) “Ultra Plus” drives capable of 40 MHz operation. LVD disk drives can also function in the slower SE mode. The first drive in the chain of drives may need to be connected by a cable over three feet long. This introduces signal degradation that is often overcome by introducing redrive circuitry to boost signal quality. This is an expensive solution and a much easier solution is presented: install a jumper between the last drive in the chain and the first drive. However, if LVD bus mode is used, then this jumper solution does not work and the jumper must be removed. Disk drives in a server system are “hot swappable,” which means they can be changed at run time without shutting down the system. A method and an apparatus is provided for dynamically testing for the appropriate mode of bus operation based on the currently installed disk drives and adjusting the jumper setting accordingly.

    Abstract translation: 提出一种动态配置系统总线拓扑的方法和装置。 在优选实施例中，系统总线是连接“菊花”链驱动器的小型计算机系统接口（SCSI）总线。 使用两种类型的磁盘驱动器：具有20MHz操作的单端（SE）“Ultra”驱动器和能够进行40MHz操作的LVD（低电压差分）“Ultra Plus”驱动器。 LVD磁盘驱动器也可以在较慢的SE模式下运行。 驱动器链中的第一个驱动器可能需要通过三英尺长的电缆连接。 这导致信号劣化，通常通过引入重新启动电路来提升信号质量来克服。 这是一个昂贵的解决方案，提供了一个更简单的解决方案：在链中的最后一个驱动器和第一个驱动器之间安装跳线。 但是，如果使用LVD总线模式，则该跳线解决方案不起作用，并且必须移除跳线。 服务器系统中的磁盘驱动器是“热插拔”，这意味着它们可以在运行时更改而不关闭系统。 提供一种方法和装置，用于基于当前安装的磁盘驱动器动态测试适当的总线操作模式，并相应地调整跳线设置。

    Abstract: An embodiment of this invention provides a system and method for a diagnostic computer application executing on a host computer to extract vendor unique diagnostic information from an attached peripheral device. The peripheral device is pre-configured to respond with device unique information in response to certain standard interface protocol inquiries. Standard interface inquiry commands are used to extract detailed instructions from the device. These instructions may contain device unique small computer system interface (SCSI) command sequences, for example. The command sequences allow a user of the host computer to extract detailed data from the peripheral device about the peripheral device's operational, performance and health statistics.

    Abstract: A data processing system, method, and product are disclosed for providing an adaptive fast write cache for storage devices. A write cache is provided in a storage device. A FAST WRITE operation is executed utilizing the write cache only when writing particular types of data. A command complete status is returned prior to writing data when a FAST WRITE operation is executed, and a command complete status is returned only after writing data when a FAST WRITE operation is not executed.

    Abstract: A method for detecting head-to-disk interference events in a disk drive is provided. The invention comprises coupling a transducer to an air filter in the disk drive, wherein the transducer detects changes in magnetic readings due to debris produced by physical contact between a read/write head and a magnetic storage medium (head crash). The recirculation filter is monitored during disk drive operations and comparing magnetic readings from the transducer with defined parameters. If the transducer readings exceed the defined parameters, the spindle motor of the disk drive is shut off, thus stopping the rotation of the disk and minimizing data loss and damage due to the head crash.
