Abstract
In order to ensure that a bandwidth allocated to each tenant of a plurality of tenants of a data storage device is maintained, a controller of the data storage device may split a large read command, received from a host device, into a plurality of chunks, where each chunk corresponds to a distinct portion of the split large read command. Because the allocated bandwidth for a tenant is static, one or more chunks of the plurality of chunks, up to the allocated bandwidth, are executed, such that the bandwidth required to perform the one or more chunks does not exceed the allocated bandwidth for the particular tenant. Split information is added to the plurality of chunks in order to maintain coherency when executing the one or more chunks. Therefore, the agreed-upon allocated bandwidth for each tenant is maintained while performing large read commands requiring more bandwidth than allocated.
