摘要:
A method is disclosed to set signal compensation settings for a data storage device comprising a first port and a second port, where that first port is interconnected to a first switch via a first communication pathway having a predetermined first length. The method determines first signal compensation settings based upon the first length.

A method is disclosed to set the speed of a network. The method supplies a network interconnected with a system controller and a plurality of switch domains, where each of those plurality of switch domains comprises one or more information storage devices and a switch domain controller, and sets by each of the plurality of switch domains a signaling rate for that switch domain. The method queries in-band by the system controller each of the plurality of switch domains for that switch domain's signaling rate, and provides in-band by each of the plurality of switch domains the signaling rate for that switch domain. The method provides in-band by the system controller to each of the plurality of switch domains a first speed selection command specifying a first network speed, and resets by each of the plurality of switch domains the signaling rate for that switch domain to the first network speed.
摘要:
A method to supply power to one or more battery-backup assemblies, wherein the method supplies a first controller, a second controller, a first battery-backup assembly, and a second battery-backup assembly. The method further supplies a power bus interconnected to the first controller, the second controller, the first battery-backup assembly, and the second battery-backup assembly, and a first power supply and a second power supply interconnected with the power bus. The method provides power to the first controller and to the second controller and to the first battery-backup assembly over a first period of time, and provides power to the first controller and to the second controller and to the second battery-backup assembly over a second period of time, where the first period of time differs from the second period of time.
摘要:
A method is disclosed to selectively provide power to a component disposed in an information storage and retrieval system, where the method supplies a controller comprising a control portion in combination with a plurality of components comprising one or more host adapters, one or more device adapter ports, and a Fibre Channel switch. The method monitors the performance of each of those components. The method discontinues the supply of power to first component while continuing to provide power to the remaining plurality of components. The method then resumes providing power to the first component while continuing the supply of power to the remaining plurality of components.
摘要:
To prevent current inrush from exceeding power limitations of a power supply or a power domain in a multiple disk drive system the drives are powered-on in a controlled sequence. In a multi-drive blade storage subsystem, a subsystem control module inventories the locations of the hard drives in one or more drive enclosure blades and maintains information about the boundaries of one or more power domains. The subsystem control module may direct one of several drive power-on sequences, none of which allow current inrush to exceed the allowable current of each power domain.
摘要:
An apparatus and method are disclosed to configure, format, and test, a data storage subsystem product. The method supplies a data storage subsystem product comprising one or more host computer ports, a processor, one or more data storage device ports, and one or more data storage devices interconnected to the one or more data storage device ports. The method further supplies a configuration appliance comprising a storage configuration. The method connects the configuration appliance to one of the one or more storage device ports, boots up the data storage subsystem product, discovers the configuration appliance by the data storage subsystem product, imports storage configuration data into the data storage subsystem product, formats the one or more data storage device, and tests the input and output data transfer rates for the data storage subsystem product, wherein the formatting and testing are initiated concurrently.
