摘要： An indicator light, such as an LED, for a computer disk drive module is controlled via an external controller. The disk drive module monitors a disk drive and determines a desired state of the LED, such as on, off or flashing, to indicate a status of the disk drive. The disk drive module provides a modulated signal carrying data that identifies the desired state on a path coupled to the indicator light and a terminal that is accessed by the external controller. The controller implements an algorithm for driving the indicator light, where the algorithm receives, as a first input, the desired state determined from the demodulated signal and, as a second input, information obtained from monitoring the disk drive module. The controller itself may obtain this information or receive it from a higher-level system controller.

摘要： A high density storage enclosure includes a plurality of storage devices, such as hard disk drives, positioned within a cooling airflow. Data to be stored to a storage device is received and a determination is made as to the expected usage of the data relative to other data stored on devices within the enclosure. The data is stored in a device having a position within the airflow relative to the source of the airflow in direct relationship to the relative expected usage of the data. Thus, data having a higher expected usage is stored in a device closer to the airflow source relative to other data having a lower expected usage and data having a lower expected usage is stored in a device farther from the airflow source relative to other data having a higher expected usage. Additionally, data may be dynamically relocated based upon actual usage.

摘要： A storage system includes a RAID adapter, disk array switches, sub-processors, and hard disk drives (HDDs). A disk-related operation is initiated in the RAID adapter. The RAID adapter dispatches a command to a disk array processor (or sub-processor) in an enclosure for the processor to perform the operation on one or more drives. The adapter may dispatch the command to a processor in a single enclosure through a disk array switch or to processors in multiple enclosures through switches in the upstream enclosures. The adapter is then free to perform other functions. The processor commences the specified operation on one or more selected drives, either sequentially one at a time or sequentially more than one (or all) at a time. Upon completion of the operation, the results are transmitted by the processor and received by the adapter. Thus, by offloading the task to the distributed sub-processors, the burden on the RAID adapter is significantly reduced, system bandwidth usage is reduced, and access to other drives within the enclosure (as well as within other enclosures) may be maintained. Tasks which may be offloaded in such a manner include, but are not limited to, drive firmware updating, drive scrubbing and secure data erasure.

摘要： A method is disclosed to assign network addresses in a storage array disposed in a data storage and retrieval system comprising (P) data storage devices disposed in (N) data storage device assemblies. The method configures the (N) data storage device assemblies to comprise a spare data storage device assembly and a first storage array comprising (N−1) active data storage device assemblies, wherein each data storage device configured in the first storage array is assigned a network address, and wherein one of the spare data storage device disposed in the spare data storage device assembly is assigned a network address. In the event the method detects a failed data storage device disposed in the first storage array, then the method forms a second storage array comprising the first storage array, except the failed data storage device, in combination with the (i)th spare data storage device.

摘要： A method is disclosed to assign addresses to a plurality of data storage devices. The method provides a switch and (N) data storage devices, where each of those (N) data storage devices is interconnected with said switch. The method further establishes (M) device addresses, where (M) is less than (N), and assigns a different one of each of the (M) device addresses to a different one of the (N) data storage devices, such that the (N) data storage devices comprise (M) address-assigned data storage devices and (P) non-address-assigned data storage devices. The method then detects a failure of the (i)th address-assigned data storage device, and transfers the (i)th address from the failed address-assigned data storage device to the (j)th data storage device, where that O)th data storage device comprises one of the (P) previously non-addressed data storage devices.

摘要： Because cable length affects signal quality, amplifying signals differently to account for cable length (“tuning”) becomes especially important when high speed signals are used. Cable length information may be stored in a non-volatile memory which may be integrated into a cable assembly or may be a discrete component between the cable and an interface. Rather than using a dedicated data line to the memory component a ground line may be connected to the memory component and multiplexed. During normal operation the selected line is grounded through a switching device. When a cable is detected, a management controller changes the state of the switching device to decouple the selected line from ground to allow the management controller access to the data stored in the memory component, including cable length information. The selected line is then re-coupled to ground and interface circuits may be tuned for the cable length.

摘要翻译： 由于电缆长度影响信号质量，因此当使用高速信号时，放大信号会因电缆长度（“调谐”）变得尤为重要。 电缆长度信息可以存储在可以集成到电缆组件中的非易失性存储器中，或者可以是电缆和接口之间的分立组件。 不是将专用数据线用于存储器组件，而是将接地线连接到存储器组件并进行多路复用。 在正常工作期间，所选择的线路通过开关装置接地。 当检测到电缆时，管理控制器改变开关装置的状态以将所选线路与地线分离，以允许管理控制器访问存储在存储器部件中的数据，包括电缆长度信息。 然后将所选择的线重新耦合到地，并且可以针对电缆长度来调整接口电路。

摘要： A storage system includes a RAID adapter, disk array switches, sub-processors, and hard disk drives (HDDs). The system permits the isolation of a suspected faulty HDD to allow diagnostics to be performed without impacting operation of the rest of the system. Upon detection of a possible fault in a target HDD, a private zone is established including the target HDD and one of the sub-processors, thereby isolating the target HDD. The sub-processor performs diagnostic operations, then transmits its results to the adapter. A faulty HDD can then be fully isolated and the private zone is disassembled, allowing the sub-processor to rejoin the network.

摘要： One or more layers of constrained layer damping material is strategically placed within a data storage library having one or more sources of rotational vibration energy. Data storage devices, such as disk drives, are isolated from each other and from a drive tray by a first layer of constrained layer damping material. The drive trays are isolated from drive enclosure bays by a second layer of constrained layer damping material. A third layer of constrained layer damping material isolates each drive enclosure bay from the housing of the data storage library. The net effect is a significant reduction of the amount of rotational vibration energy arriving at each data storage device from other system components, such as a blower module. Additionally, the amount of rotational vibration energy arriving at each data storage device from other data storage devices is also reduced. By mounting the data storage devices to the drive trays in a single plane, the rigidity and mass of the drive tray is increased, reducing its susceptibility to external rotational vibration energy.
