Abstract

A storage device may include a storage medium, a storage device controller coupled to the storage medium, a host interface coupled to the storage device controller, and an attachable module interface configured to connect an attachable compute module to the storage device controller. The attachable module interface may include a data interface, a side-band interface, and/or a power interface. The attachable module interface may include a connector configured to connect the attachable compute module to the storage device controller. The storage device may include an enclosure having an opening configured to enable the attachable compute module to be connected to the attachable module interface through the opening. The storage device controller may be configured to utilize one or more resources of the attachable compute module. The storage device controller may be configured to communicate with the attachable compute module through one or more command extensions of a storage protocol.

First claim

The invention claimed is:
