    Abstract: A method, apparatus, and computer program product are disclosed for controlling accesses of drives in a storage subsystem. A first array of a first type of drive is provided. The first type of drive is a server class of drive. A second array of a second type of drive is provided. The second type of drive is a PC class drive. The first and second arrays are bound together to form a single array of drives. The single array of drives is presented to a host that is coupled to the storage subsystem as a single array. The host is unaware that the single array includes two different types of drives. Data is stored in the second array of drives. Data is migrated from the second array of drives to the first array of drives when an access rate of the second array of drives exceeds a threshold access rate for the second type of drive.

    Abstract: Method, system and computer program product for reporting and recovering from uncorrectable data errors in a data processing system using the Advanced Technology Attachment (ATA) or the Serial ATA (SATA) protocol. The invention utilizes the data scrubbing functionality of SCSI hard drives to provide a higher level of data integrity in an operating system implemented RAID environment. If an uncorrectable data error is found on a hard drive during a background data scrubbing operation, information concerning the data error is logged in a S.M.A.R.T. (Self Monitoring Analysis and Reporting Technology) error data structure. When the host operating system identifies the uncorrectable data error during normal operation, a Host Array Manager issues a Write Command to write the data from a redundant drive after the defective Logical Block Address (LBA) has been reassigned.

    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.
