Front input/output (i/o) expansion module for a computing device

An input/output (I/O) expansion enclosure, comprising:

• a rackmountable chassis;
• a riser card mounted within the chassis, the riser card comprising one or more I/O expansion card slots each configured to receive a corresponding I/O card;
• and
• a cable configured to communicatively couple the one or more I/O expansion card slots of the riser card to an a Non-Volatile Memory Express (NVME) drive slot on a NVME backplane of a rackmountable computing device.

A system comprising:

• a rack unit comprising one or more rack spaces;
• a computing device installed in a first rack space of the rack unit, the computing device comprising a peripheral component bay accessible from a first side of the computing device, wherein the peripheral component bay comprises a storage device backplane having storage device slots each configured to receive a corresponding storage device;
• a conversion module installed in the peripheral component bay and coupled to at least one of the storage device slots present on the storage device backplane;
• and
• an input/output (I/O) expansion module installed in a second rack space, the I/O expansion module comprising:
• a chassis;
• and
• a riser card mounted within the chassis, the riser card comprising one or more I/O expansion card slots each configured to receive a respective I/O expansion card;
• wherein the one or more I/O expansion card slots of the riser card and the computing device are communicatively coupled to each other via a cable connected between the conversion module and the I/O expansion module.
