摘要:
A computer determines an intrinsic read speed and an intrinsic write speed associated with a first disk and a second disk. The computer receives a request to read a portion of data, wherein the portion of data is stored redundantly on both the first and second disk. The computer identifies a first latency associated with reading the portion of data from the first disk, where the first latency is based on at least the intrinsic read speed and the intrinsic write speed associated with the first disk. The computer identifies a second latency associated with reading the portion of data from the second disk, wherein the second latency is based on at least the intrinsic read speed and the intrinsic write speed associated with the second disk. The computer determines that the first latency exceeds the second latency. The computer selects the second disk to read the portion of data.
摘要:
Software that performs the following steps: (i) collecting a set of sampling value(s), where each sampling value of the set of sampling value(s) respectively corresponds to an amount of overprovisioning-related data stored in a non-volatile memory device (NVMD) at the time the corresponding sampling value is collected; and (ii) determining an overprovisioning ratio for use with the NVMD based, at least in part, on the set of sampling value(s). The overprovisioning-related data is any data stored in overprovisioning space as a result of overprovisioning-type operations.

摘要:
Embodiments of the present invention provide an apparatus and methods for converting a volatile memory module device to a non-volatile memory module device. In one embodiment, a male contact edge of a memory module device is inserted to a first memory module device socket of a memory module device adaptor, the memory module device adaptor having a first male contact edge. Power is provided to the memory module device in the event of a system failure. Diodes operatively connected to one or more power pins of the first memory module device socket prevent current from flowing to the battery to one or more power pins of the male contact edge of the memory module device adaptor. Applications needing dedicated memory are registered and, in the event of a system failure memory module device data associated with the registered applications can be recovered without the use of flash memory.
