20090268415 | Battery Backup Unit (BBU) assembly - The present invention is a Battery Backup Unit (BBU) Assembly. The BBU Assembly may include a Printed Circuit Board (PCB). The BBU Assembly may further include a protection circuit connected to the PCB. The BBU Assembly may further include a battery pack connected to the PCB. The battery pack may include a plurality of Lithium-ion (Li-ion) cells. The battery pack may be configured as a 2-cell series stack, a 3-cell series stack, or a 4-cell series stack. The BBU Assembly is configured for electrically connecting the battery pack to the protection circuit. | 10-29-2009 |
20100194341 | DEVICE AND METHOD FOR IMPROVED BATTERY CONDITION LEARN CYCLE - Embodiments of the invention include a device and method for improved battery learn cycles for battery backup units within data storage devices. The backup unit includes a first battery pack, a corresponding charge capacity gauge, one or more second battery packs, a corresponding charge capacity gauge, and a controller switch configured to select only one battery pack for a learn cycle at any given time. The charge capacity gauges are such that, at the end of the learn cycle discharge phase, the depth of discharge of the learn cycle battery pack is such that the charge capacity of the learn cycle battery pack combined with the full charge capacity of the remaining battery packs is sufficient for the device cached data to be off-loaded to a physical data storage device, and the data storage device does not have to switch from a write-back cache mode to a write-through cache mode. | 08-05-2010 |
20120185626 | METHOD AND APPARATUS FOR DIVIDING A SINGLE SERIAL ENCLOSURE MANAGEMENT BIT STREAM INTO MULTIPLE ENCLOSURE MANAGEMENT BIT STREAMS AND FOR PROVIDING THE RESPECTIVE BIT STREAMS TO RESPECTIVE MIDPLANES - A controller is provided that receives a single enclosure management (EM) serial bit stream from an expander or other device and divides the EM serial bit stream into multiple EM serial bit streams for delivery to multiple respective midplanes or backplanes. In this way, a separate EM serial bit stream is provided to each midplane or backplane without having to increase the number of ports that are available on the expander or other device that interfaces with the backplane or midplane. | 07-19-2012 |
20140087570 | CABLE EXIT METHODS FOR PCIE CARDS - The present disclosure is directed to an apparatus configured for providing a plurality of exit routes to a single type of cable. The apparatus includes a board configured to have a notch. The notch is dimensioned to have a first predetermined distance from a lowest edge of the notch to a pin A1 location on the board and a second predetermined distance from an edge of the board to the pin A1 location. The apparatus also includes a plurality of connectors configured for receiving a cable of the plurality of the single type of cable. Each cable is inserted into a respective connector, and each cable exits the board through the notch. The cable may exit the board through a plurality of routes without requiring changes to the dimension of the board or placement of the connectors. | 03-27-2014 |
