20180003743, Jan 4, 2018

Filed:

Jun 30, 2016

Appl. No.:

15/198842

Inventors:

- Irvine CA, US
CHARLES A. NEUMANN - LAKE FOREST CA, US

International Classification:

G01R 19/00
G01R 13/02

Abstract:

Systems and methods are disclosed for determining an input voltage level of an input voltage received by a connection cable. A monitoring component may determine whether the input voltage level matches one of a plurality of voltage levels. The connection cable may include an indicator component that may indicate which of the plurality of voltage levels matches the input voltage level.

Appl. No.:

14/983221

Inventors:

- Irvine CA, US
CHARLES A. NEUMANN - LAKE FOREST CA, US

International Classification:

G06F 1/10
G06F 13/38
G06F 13/40
G06F 13/16

Abstract:

A device may comprise data storage, a power manager and a bridge device that is coupled to the data storage and to the power manager, and configured to bridge between at least a first data protocol and at least a second data protocol. The bridge device may comprise a UART, a first clock, a second clock and bridge device firmware configured to cause the bridge device to selectively configure the UART for communication using the first clock or the second clock. The power manager may be configured to, when a command is to be issued to the data storage when the bridge device firmware has configured the UART for communication using the first clock, assert a signal that causes the bridge device firmware to stop configuring the UART for communication using the first clock and to configure the UART for communication using the second clock.

Inventors:

- Irvine CA, US
CHARLES A. NEUMANN - LAKE FOREST CA, US

International Classification:

G06F 17/30
G06F 21/62

Abstract:

Systems and methods are disclosed for replicating data across data storage devices of a logical volume. A data storage system may create a logical volume by grouping the multiple data storage devices together. The data storage devices may be external standalone data storage devices. The data storage system may also replicate data across the logical volume.

Assignee:

WESTERN DIGITAL TECHNOLOGIES, INC. - Irvine CA

International Classification:

G06F 1/26
G06F 3/06

US Classification:

711114, 713310

Abstract:

A storage device including a communications interface configured to receive data and power, a plurality of disk drives configured to be powered only by the power received by the communications interface, a controller configured to configure the plurality of disk drives as a redundant array of independent disks, a power regulator configured to transmit the received power from the communications interface to the plurality of disk drives, and a peak current reduction circuit configured to reduce peak current usage by the plurality of disk drives.
