1. A method implemented by a switch device that is configured to communicate with a plurality of hosts and a solid state drive (SSD), the plurality of hosts including a first host and a second host, the method comprising:

receiving, at the switch device, a first memory access command from the SSD, the first memory access command including an indication of the first host to indicate the first memory access command is intended for the first host;

using, by the switch device, the indication of the first host in the first memory access command to route the first memory access command to the first host; and

removing, by the switch device, the indication of the first host from the first memory access command prior to sending the first memory access command to the first host via a peripheral computer interface express (PCIe) interface of the switch device.
