Abstract

The present disclosure describes aspects for providing Quality of Service (QoS) over a virtual interface for solid-state storage. In some aspects, a storage media switch receives, from a host device, an input/output (I/O) command for data access including an identifier for a virtual interface associated with a namespace through which solid-state storage is accessible. The switch determines an amount of the data that the I/O command will access through the namespace. A determination is made whether the amount of data that the I/O command will access through the namespace exceeds a predefined threshold for data access through that namespace. In response to determining that the amount of data does not exceed the predefined threshold, the I/O command is released to the solid-state storage to enable the data access. By so doing, the switch may provide QoS for the virtually accessed solid-state storage based on an access parameter of the namespace.
