System and method for performing raid i/o operations in pcie-based storage resources

A method for performing a write operation, comprising:

• overlaying memory address space of storage resources of a destination logical unit for the write operation onto a source address;
• determining whether the destination logical unit is a RAID0 array;
• if the destination logical unit is a RAID0 array, generating a source address for each storage resource of the destination logical unit;
• and
• multicasting a plurality of transaction layer packets, each transaction layer packet associated with a corresponding storage resource of the destination logical unit.

A Peripheral Communication Interconnect Express (PCIe) switch configured to:

• interface between an information handling system and a plurality of storage resources;
• overlay memory address space of a source logical unit for a read operation onto a destination address, the source logical unit including two or more of the plurality of storage resources;
• determine whether the source logical unit is a RAID0 array;
• if the source logical unit is a RAID0 array, generate a source address in a receive buffer for each storage resource of the source logical unit;
• and
• store data received from each storage address of the logical unit at the generated source address of the receive buffer associated with such storage resource.
