Mapping object interface into a powered storage device system

摘要

Apparatus and associated method contemplating: operating a storage server having access to a plurality of storage devices, at least a first storage device of the plurality of storage devices defining a first bank and at least a second storage device of the plurality of storage devices defining a second bank; during a first time interval, energizing the first bank to enable data transfer, and de-energizing the second bank to disable data transfer; during the first time interval, mapping data received from the storage server to the first bank; during a second time interval that begins before a storage capacity of the first bank is full, de-energizing the first bank to disable data transfer, and energizing the second bank to enable data transfer; and during the second time interval, mapping the data received from the storage server to the second bank.

1. A method comprising:
operating a storage controller having data storage access to each of a plurality of storage devices grouped into a first bank of storage devices and a second bank of different storage devices, and the storage controller caching application data from a host pending transfer to at least one of the banks of storage devices; during a first time interval, energizing the first bank of storage devices to enable data transfer; during the first time interval, mapping the cached application data to the first bank of storage devices; during a second time interval that begins before a storage capacity of the first bank of storage devices is full and in response to longevity management logic configured to equalize utilizations of the banks, energizing the second bank of storage devices to enable data transfer; and during the second time interval, mapping the cached data to the second bank of storage devices.
