摘要： A system migrates data between a source device and a target device in a storage system. A processor is operational within a local domain of the storage system. A redundant array of independent disks (RAID) controller electrically connected to the processor. The RAID controller divides a capacity of the source device into a plurality of sub-regions, locks the sub-regions from storage activity, establishes a mirroring relationship for write data updates between the source device and target device, and assigns the processor to copy data from the source device to the target device. A method of migrating data includes dividing a capacity of a source device into a plurality of sub-regions, locking the sub-regions from storage activity, establishing a mirroring relationship for write data updates between the source device and a target device, and assigning a local processor to copy data from the source device to the target device.

摘要： 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 assign addresses to a plurality of data storage devices, by providing 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) arbitrated loop physical addresses (“AL_PAs”), where (M) is less than (N), and assigns a different one of each of the (M) AL_PAs to a different one of the (N) data storage devices, such that the (N) data storage devices comprise (M) AL_PA-assigned data storage devices and (P) non-address-assigned data storage devices. The method then detects a failure of an (i)th AL_PA-assigned data storage device, and transfers the (i)th AL_PA from the failed address-assigned data storage device to a (j)th data storage device, where that (j)th data storage device comprises one of the (P) previously non-addressed data storage devices.

摘要： A method provides for dynamic data logging in a storage subsystem. The method determines if a plurality of storage devices has been assigned as a plurality of hot spare devices in the storage subsystem. If the plurality of hot spare devices are assigned, the method determines from the plurality of hot spare devices whether a plurality of storage types with a maximum number of spare devices is present. If a plurality of storage types is present, the method selects a hot spare device from a storage type having the smallest capacity to assign as a logging device, otherwise, the method calculates a plurality of ratios of a first number of storage devices of a shared storage type to a second number of storage devices to which the first number of storage devices can act for as hot spare devices, selecting a storage device with the lowest ratio as the logging device.

摘要： A memory system has mechanisms for scavenging capacity of a super capacitor by removing, or reducing, system load from the super capacitor when the super capacitor voltage decays below a low threshold. The mechanisms then restore the system load to the super capacitor when the super capacitor voltage ramps back above a high threshold. A controller may reduce system load by placing a volatile memory system in a standby state and disabling a field effect transistor to remove power from a non-volatile memory system. A controller may adjust the high threshold and/or a low threshold by setting a digitally controlled potentiometer in a threshold detect circuit via an I2C bus.

摘要： A mechanism for in situ verification of capacitive power support is provided. A memory system uses a super capacitor to support a voltage rail when input power is lost or interrupted. The voltage discharge curve is a function of load and capacitance of the component. By stepping the regulated power supply to a lower output within the voltage range and recording voltage and current draw at the super capacitor as it discharges to the new regulator output voltage, the super capacitor holdup capability can be tested.

摘要： A storage system includes a RAID adapter, disk array switches, sub-processors, and hard disk drives. A disk-related operation is initiated in the RAID adapter which 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 upstream enclosures. The adapter is then free to perform other functions. The processor commences the specified operation on one or more selected drives. Upon completion of the operation, the results are transmitted by the processor and received by the adapter. Offloading the task to the distributed sub-processors reduces the burden on the RAID adapter, reduces system bandwidth usage, and enables access to other drives to be maintained.
