Modifying NVMe Physical Region Page List Pointers and Data Pointers to Facilitate Routing of PCIe Memory Requests

A non-transitory computer-readable medium storing instructions that, when executed by one or more processors, cause the one or more processors to at least:

• receive a first command from a host associated with a storage system which includes two or more hosts, wherein the first command comprises one or more physical request page (PRP) entries associated with the non-volatile memory express (NVMe) standard;
• modify the one or more PRP entries with an indication of the host;
• send a second command with the modified one or more PRP entries to a solid state drive (SSD);
• receive a memory request from the SSD, wherein the memory request comprises the modified one or more PRP entries;
• and
• route the memory request to the host based on the indication of the host in the modified one or more PRP entries.

A non-volatile memory express (NVMe) switch comprising:

• a command processor comprising instructions stored in memory of the NVMe switch that, when executed by one or more processors of the NVMe switch, cause NVMe switch to at least:
• receive, by the command processor, a first command from a host associated with a storage system which includes two or more hosts, wherein the first command comprises one or more physical request page (PRP) entries associated with the non-volatile memory express (NVMe) standard;
• modify, by the command processor, the one or more PRP entries with an indication of the host;
• and
• send, by the command processor, a second command with the modified one or more PRP entries to a solid state drive (SSD);
• and
• a data processor comprising instructions stored in memory of the NVMe switch and that, when executed by one or more processors of the NVMe switch, cause the NVMe switch to at least receive, by the command processor, a memory request from the SSD, wherein the memory request comprises the modified one or more PRP entries;
• and route the memory request to the host based on the indication of the host in the modified one or more PRP entries.
